Metal Halide Lamp casting method is commonly used resin sand casting, followed by special casting methods, such as: metal casting, investment casting, plaster casting. The sand casting sand can be divided into clay, organic binder sand, resin from the hard sand, lost foam, etc.. When the wet type can not meet the requirements and then consider the use of clay, sand is dry sand, dry sand or other sand. Green sand mold castings from a few kilograms of weight can be up to tens of kilograms, while the production of dry clay can weigh hundreds of tons of castings. Aluminum Casting casting and production methods should be suited to volume, low pressure casting, die casting, centrifugal casting and other casting methods, equipment and tooling for the price of expensive, so only suitable for mass production.

An unfinished workpiece requiring cnc machining will need to have some material cut away to create a finished product. A finished product would be a workpiece that meets the specifications set out for that workpiece by engineering drawings or blueprints. For example, a workpiece may be required to have a specific outside diameter. A lathe is a machine tool that can be used to create that diameter by rotating a metal workpiece, so that a cutting tool can cut metal away, creating a smooth, round surface matching the required diameter and surface finish. A drill can be used to remove metal in the shape of a cylindrical hole. Other tools that may be used for various types of metal removal are milling machines, saws, and grinding tools. Many of these same techniques are used in woodworking.
  The three principal cnc machining processes are classified as turning, drilling and milling. Other operations falling into miscellaneous categories include shaping, planing, broaching and sawing. Turning operations are operations that rotate the workpiece as the primary method of moving metal against the cutting tool. Lathes are the principal machine tool used in turning. Milling operations are operations in which the cutting tool rotates to bring cutting edges to bear against the workpiece. Milling cnc machines are the principal machine tool used in milling. Drilling operations are operations in which holes are produced or refined by bringing a rotating cutter with cutting edges at the lower extremity into contact with the workpiece. Drilling operations are done primarily in drill presses but not uncommon on the lathes or mills. Miscellaneous operations are operations that strictly speaking may not be machining operations in that they may not be chip producing operations but these operations are performed at a typical machine tool. Burnishing is an example of a miscellaneous operation. Burnishing produces no chips but can be performed at a lathe, mill, or drill press.
  Machining requires attention to many details for a workpiece to meet the specifications set out in the engineering drawings or blueprints. Beside the obvious problems related to correct dimensions, there is the problem of achieving the correct finish or surface smoothness on the workpiece. The inferior finish found on the machined surface of a workpiece may be caused by incorrect clamping, dull tool, or inappropriate presentation of a tool. Frequently, this poor surface finish, known as chatter, is evident by an undulating or irregular finish, and the appearance of waves on the machined surfaces of the workpiece.
  As a commercial venture, machining is generally performed in a machine shop, which consists of one or more workrooms containing major machine tools. Although a machine shop can be a stand alone operation, many businesses maintain internal machine shops which support specialized needs of the business.

Casting Director Strategy for Actors

Author: kay white
The Actor’s Casting Director Strategy

I have to tell you, hands down, the question I am asked more than any other question from actors is, "How can I get more auditions?" What's interesting to me about this question is that I rarely get asked, "How can I book more jobs?" My question for you is, "Do you really want auditions? Or do you want offers?"

The trick to longevity in an acting career is to stop focusing on auditions and instead start focusing on building relationships, so that you can get offers. Some of the best people to build relationships with are, of course, casting directors. These are the people directly responsible for calling you in on roles that you're right for.

One of my favorite ways to truly become known by casting directors is through workshops, seminars and classes. Now, I know there is a lot of controversy around whether or not actors should invest money in meeting casting directors, but the truth is that in every industry, there are programs build for a business owner to invest a little bit of money in order to build lasting relationships. I myself am a member of two networking organizations where I pay money to attend events. Casting director workshops are truly no different.

I'm going to use the word workshop as an umbrella term to speak about seminars, classes, and intensives. As an actor, if you really want to become known by casting directors, stop trying to see as many of them as you can and instead concentrate on the select few you want to build a relationship with. I recommend coming up with a list of nine or fewer casting directors and attending workshops with them on a consistent basis, so that they can really begin to know your work and remember you when roles come up.

In general, I recommend that you attend workshops once every other month with everyone on your casting director target list until you've seen them seven times. Unfortunately, this is not a magic pill; this is an investment of a little bit of money and consistent workshopping over the course of about twelve to fourteen months. However, if you stick with this strategy, you will find very quickly that casting directors won't just recognize your face; they will remember your name and begin to call you in for jobs that you're right for.

Quality die casting to meet your business goals

Author: solutionFinder

A few months ago, DDK LTD. started to search for a zinc die casting company to replace their wear out water proof circular connector production line and low competition electrical connector price in Japan. Through TAIWAN TOTAI, DDK LTD. reached Accucision Diecast and gave them a pressure die casting challenge.

In Japan, electrical connectors are made with single cavity molds and the three holes are fabricated by staff afterward. In order to decrease costs and increase electrical connector's production capability, DDK LTD. asked for one-time fabrication using a Double Cavity Mold and at the same time adding three holes on the circular connectors. All of the Japanese mold designers thought that was impossible at that time. To meet the request, Accucision Diecast engineers spent days to design a suitable double cavity mould.

In the end, Accucision Diecast engineers added three inner sliding blocks on the mold to meet the hole requirement on the circular connectors. DDK LTD. was thrilled and surprised to see the result of the circular connectors, which met their requirements and the quality, was excellent. After testing and confirming the mould and connector quality, DDK LTD. ordered more than 70,000electrical connectors in four months to make up for the shortage from previous months. Accucision Diecast's precision zinc die casting skill and excellent mould design capability had not only created a mold that saved extra manual work but also increased production speed using a double cavity mould.

There are many challenges in producing efficient die casting designs, and an elite mould design can be cost-saving. Accucision Diecast acts as a consultant to customize your die casting mould so that it suits your production expectations, and only experienced engineers who are talented in problem solving can do the die casting job. Once the mould is on the production line, engineer's precise control of the PLC system is the key for die casting production. Any slight adjustment to the production machine can cause failures, hence, every engineer at Accucision Diecast has more than 6 years of die casting experience. One of the important factors to produce high quality die casting connectors or adapters is the quality of alloy. Accucision Diecast uses 2:1 world standard of alloy material to ensure the hardness and quality of each die casting production.

Sand Castings in China

Author: ironfoundry

Sand castings are also known as sand mold castings, sand mould castings, sand cast or sand molded castings.

Sand casting process uses sand shell and sand core as the molding material, the liquid metal filling in gravity to produce the casting mold casting method. Steel, iron, and most non-ferrous alloy castings are available in sand casting methods. As used in sand casting molding material is cheap, easy to mold manufacturing, casting a single piece on the production, mass production and mass production can meet for a long time, has been casting the basic process.

Casting process is generally divided into three basic parts, mold preparation, casting metal casting the final preparation and processing. Preparation is to mold the liquid into a solid cast metal container, the mold according to the materials used can be divided into ceramic, metal type, sand, clay and so on. According to the number used can be divided into semi-permanent and permanent-type and one-off type. The quality of the mold to prepare the final casting only directly affect the quality of the main factors. Melting and casting metal casting, casting metal (cast alloy) main cast steel, cast iron and cast non-ferrous alloys. Casting surface treatment including the removal of foreign body, casting processing and testing, relief grinding burrs and other projections as well as Phi seam heat treatment, plastic surgery, anti-rust treatment and rough so.

Manufacture of basic raw material is sand casting sand and sand binder. The most commonly used casting sand is silica sand. Silica sand can not meet the requirements of high temperature performance when used zircon sand, chromite sand, sand and other special corundum sand. To make the sand mold and core made of a certain intensity, in the handling, combined type and pouring liquid metal without deformation or damage when, generally by adding sand in the foundry binder, loose sand will bond together to form the sand. Sand casting used in the sand by the sand outside the binder used in different ways and build strength into the wet clay, sand, clay, sand and dry sand three kinds of chemical hardening.

Caste in India

Author: ROY T JAMES

Caste in India - A Quantum View

As Shri Bhimrao Ambedkar says “Subtler minds and abler pens than mine have been brought to the task of unraveling the mysteries of caste; but unfortunately it still remains in the domain of the ‘unexplained’ not to say of the ‘ununderstood’1a”. Never has this observation been more apt than now, when no aspect of social and political life of India is free of its influence. And this influence seems to be on the rise. To unravel some of the mysteries this institution holds within, let us take a journey through its origin and development.
“Caste “”, as defined, for example, by Lundenberg2 “is merely a rigid social class into which members are born and from which they can escape or withdraw with extreme difficulty”. In other words, it is a type of stratification system, which is most rigid in matters of mobility and distinction of status. Much need to be explained about the genesis of this system, though a good deal has been written about its nature, especially the various features of control influencing its members, its origins does not seem to have received enough attention. Some of the theories proposed are, racial theory -that caste system is a gift of Aryans, political theory -that caste system is an invention of Brahmins, occupational theory -that caste system is functional differentiation of occupational differences, traditional theory -that caste system is of divine origin to maintain social harmony, guild theory -that caste system is the product of interaction between guilds, tribes and religion, religious theory -that caste system is the institutionalization of prevailing customs, each caste being the followers of certain deity and evolution theory -that caste system is a result of social evolution moderated by various factors, like prejudices, lack of control mechanisms, geographic isolation of Indian peninsula as well as conquerors’ policies, especially that of the British, to name a few.

1 THEORIES OF CASTE ORIGIN-AN EXAMINATION

1.1 Racial Theory: The fact that caste names Brahmana, Kshtriya, and Visya are frequently mentioned in the RigVeda along with words like ‘dasa’, ‘varna’, gives credence to the theory that caste is an invention of IndoAryans. In ‘cultural history of India’ Al Basham mentions that caste system evolved to accommodate large variety of tribes into Aryan society during expansion of vedic Aryan territories.
However, such delineation does not take into consideration the importance generally was ascribed to ‘the moral worth’ of a man rather than his ‘birth’, which, we can see at many places in puranic literature, ‘mahabharata’ et al. Also, caste differences and demarcation of people on that basis was not considered as seriously as we do these days. In Al Baroonis India, he describes human, according to Indian thought, as “consisting of 25 elements, soul (sattva, tamas, rajas), matter, nature, will” etc, learn all these and one “will achieve salvation whatever religion one may follow”. Similar is the opinion of Sir Vincent Smith, who in ‘Asoka-his History’ says “Though each caste has its own dharma, the conduct is less rigid than it has been since Moslem invasions”. From all these, a conclusion one can reach is that, caste, as we see now, needs some more explanation, than that,” it has been evolved during intermingling of Indo Aryan local tribes.
1.2 Political Theory: In Mahabharata(shantiparva) creation of caste is given thus: “Brahma created the world entirely Brahmanic1b. Later, those Brahmins fond of sensual pleasure became kshtriyas. Those Brahmins who subsisted by agriculture neglecting their duties entered the state of Vaisya and those who were fond of mischief and falsehood sank into the condition of Sudras”. In ‘Hindu Caste System….’3, Dr Sharma explains the formation of caste thus: To meet liturgical needs, the society from among themselves would select, on the basis of skills of elocution, the Brahmins. Similarly, for administrative purposes, those with qualities of leadership would be selected….. Furthermore, visha(clan or tribe) also embodied people known as Shudra(meaning not of tribe, newcomers) representing all new comers to that particular tribe….Thus all responsibilities related to a visha could be grouped into four subcategories”, each having “their duties and skills”.
Though caste can thus be seen as having been a useful tool for maintaining social order, the fierce form it is having now needs much more explanation than what is offered by this theory.
1.3 Occupational theory: According to ‘Theodosian’ code, in early Roman Empire, son was required to follow fathers’ profession, thus maintaining availability of skill while solving the question of continuation of enterprises. That such an arrangement was widely followed can be observed in many of the popular surnames of today, Smith, Miller, Potter, to name a few.
How these occupational guilds and other family groups metamorphosed into castes, in India, while they amalgamated fully into the larger social canvas in rest of the world, is a question, needing finer minds and greater efforts perhaps, to answer.
1.4 Traditional theory, Guild theory and Religious theory: These theories propose divine intervention in human affairs. Such intervention regulates society by bringing harmony in all essential functions for social well being, mankind being left free in search of bliss. Occupational groups, which originate as a result of such harmony, on passage of time, converted themselves into castes by following endogamy. In this phenomenon of caste formation, some groups find themselves becoming endogamous and others find themselves forced into becoming so by society(by closing all avenues of social interaction).
Such a theory may be able to explain the formation of castes as a singularity in social evolution, but fails in providing rationale for the vast expanse of caste in Indian society.
1.5 Evolutionary theory: This theory, in fact, is not a new or different theory. It states, in effect, that over the years, formation of caste is influenced by all factors we have seen earlier, in some form or other.

2 THEORIES OF DEVELOPMENT OF CASTE-A STUDY

1.1 The origin and development of caste therefore narrows down to the peculiarities of Indian social evolution which could transform into castes (as they are now) under the influence of factors like the ones mentioned in these theories. The stratification property of caste, one such peculiarity, in fact, is not a monopoly of India, its mention being found at many places. History by Herodotus, Mande or Osu caste systems of Africa, division of people into four estates in medieval Europe, of feudal barons, clergy, urban merchants and the mass of people as well divisions among old Israel population having ritual ramifications are a few places where one can find a system of differentiating humans to varying levels.
Such a process of division, in fact, has been a subject of study by sociologists, notably, Herbert Spencer, who in his sociological theories have put forth following generalizations:
• The larger the number of people and internal transactions, greater will be the size and degree of internal differentiation of government.
• The greater the actual or potential level of conflict with other societies and within a society, the greater will be the degree of centralization of power in a government.
• The greater the centralization of power, the more visible class divisions will be and the more these divisions create actual or potential conflict.
Like colonies of all living species, powerful leadership and consequently concentration of power did happen in all cultures giving rise to class structures.
1.2 Thus we see, though the tendency to form social class is present in every society, in our case, the stratification became increasingly stable, crystallizing into castes. The main factor which effected this transformation, of a social class into a caste, is another peculiarity of Indian social evolution, endogamy. Says Ambedker “Remember that endogamy is foreign to the people of India…It is no exaggeration to say that with the people of India exogamy is a creed and none dare infringe it…there are more rigorous penalties for violating exogamy than there are for violating endogamy. Castes, as far as India is concerned, means superposition of endogamy on exogamy”. He further elaborates how, sati or enforced widowhood (where widow is not allowed to remarry), imposition of celibacy on widower as well as girl marriage came to be part of Indian “uxorial customs to maintain numerical parity between the two sexes”, making endogamy workable leading to perpetuation of caste system.

1.3 S Charles Hill says 1b”Instead of allowing ourselves to be misled by the outward show of Hinduism we must concentrate our attention on what the Hindu writings tell us … According to the Bhagawat Gita, to be truly wise one must have learnt:

• To control the body in its appetites and desires so that it does not injure itself or impede the free action of soul
• To act for benefit of the community without hope of reward… so long as ones duty as laid down by the requirement of caste is performed
• To resign oneself with absolute patience to pain and suffering and loss and feel no exultation in success
…………………………………………………………………
In other words, to fit oneself for the position of a ruler one must have overcome all human weaknesses and renounce all material rewards…………… It is not necessary to enter upon the requirements of other castes, for the above is sufficient to show that what differentiates them is simply character”. He continues, stressing the fact that more than one observer has commented on the purity, regularity, equity and strictness of the ancient Indian government, “The ideal Hindu kingdom is not an utopian dream, still exists in the hearts of Hindus, that it was based upon a social system which secured the happiness and contentment and loyalty of all classes of the people, and that the later stages of corruption and confusion have been due to foreign intrusion whether from central Asia or from Europe, whilst whatever unrest now prevails in India is caused by the incessant struggles of the Hindu caste ideal against alien influences.” About the caste system existing then, he says, “….. as a matter of fact, though we talk of upper and lower castes, no caste was originally considered superior or inferior…..though in the Sudra the body is predominant, in the Vaisya the reason, in the Kshtriya the heart and in the Brahmin the soul, all castes are equally manifestations of Brahma though of different qualities. The relation between a higher and lower caste is then more like that between an adult and a child than that between a noble and a serf.” He says further, “It provides every member of the community with a position which, though rigidly fixed, is fixed only by his natural limitations, and so allows him every opportunity of using to their full extent whatever abilities he may possess to the general advantage.”
The views expressed by O P Gupta5a also are not dissimilar, “Supporters of casteism oftenly quote two slokas viz. (IV.13) and (XVIII.41) of Shrimad Bhagwat Gita to support four castes by birth. Let us examine. In sloka (IV.13) Lord Krishna says: "Chaturvarnyma mayaa sristam gunkarma vibhagsah" i.e. four orders of society created by Me according to their Guna (qualities/behaviour) and Karma (profession/work/efforts). Lord Krishna does not say guna and karma of previous life. In sloka (XVIII.41) Lord Krishna says "Brahmana Kshatriya visham sudranam cha paramtapa, karmani pravibhaktani svabhavaprabhavaigunaih." It means people have been grouped into four classes according to their present life karma (profession/work) and svabhava (behaviour). `The division of labour into four categories - Brahman, Ksatriya, Vaishya and Sudra - is also based on the Gunas inherent in peoples’ nature`. Had this division been based on birth, Lord Krishna would have naturally used phrase 'Janmani pravibhaktani' in the very shloka (XVIII.41). In sloka (XVIII.42), Lord Krishna prescribes duties (karma) which one must do in order to qualify as a Brahman i.e. among other duties (karma), he must have studied Vedas and must teach Vedas to others. Thus, if a person has neither studied Veda, nor teaches Veda to others, he is not a Brahman. “
During the journeys of Hieun Tsang, he is said to have mentioned5b “…society consists of four caste groups. These four castes form classes for ceremonial purity.”

Such a system, where social life is entirely independent of political government naturally disintegrated when Indian society came into contact with various invading societies, the most potent western invasion being the one beginning with landing of Portugese adventurers at Calicut with VascoDaGama, who utilized the differences in social positions among Indians as a convenience in governance by according political legitimacy to existing differences. These differences, which were of academic interest in life thus far, might have been of great use to the invading group in governing the land.

1.4 Endogamy as a custom might have got instituted in such a social system to safeguard the thus legitimized privileges as close to oneself as possible. Ronald Inden4 in his ‘Imagined India’ argues that caste is almost a creation of western efforts to orientalise their conquered subjects. Moreover, genomic studies pertaining to origins of castes have been able to identify differences in distribution of genetic material among different caste groups. While many of those point to similar inferences, that lineages of caste groups(non tribal population) show relationship with central Asia while lineages of tribal groups are predominantly from original Indian gene pool and that genes of upper caste population have greater affinity to Europeans than to Asians7 compared to genes from lower caste population etc, Partha Majumdar et al(ISI Calcutta)8 reports after a comprehensive statistical analysis of data from ethnically diverse populations of India, that, tribal and caste populations are highly differentiated and genetic histories have been considerably obliterated making it impossible to see any clear congruence of genetic affinities.

1.5 Whatever may be the case, meaning of caste changed much, from, what Charles Hill observed1c “No caste was originally considered superior or inferior, except in sense that its bodily type represented a more or less advanced stage in human habitations which must be, in turn, occupied by the soul” to one dividing people into, groups with different responsibilities, functions and rights, i.e., different societies.

1.6 Endogamy as well as measures instituted by the invading group in governing the land might be able to put forth a rationale for development of caste, however fails in providing a reasonable explanation to the fact that we have myriad of castes, each having discernable difference in ability when compared with another caste.

3 BEGINNINGS OF CASTE EVOLUTION

1.7 Whatever the shape the evolution of caste took, it certainly resulted in a large multitude of castes, each having discernable difference in ability when compared with one another, especially intellectual. As we have seen earlier, all theories of caste formation and development fail in providing a satisfactory explanation to this phenomenon.

1.8 This could have been caused by singularities in Indian social evolution, mainly owing to changes brought in by external stimuli, two of such being:
-Foreign occupation. Conquests by Muslims, Europeans and the British, and lately
-Russian revolution and the influence of communism on Indian thought
As a result of these, caste became entrenched in Indian society, the stratification property offering much convenience in administration, each caste being a form of professional guild with more or less assured income opportunities, offering social stability. Caste being an idea which is of esoteric nature, such stratifications might have caused least consternation in everyday life.

1.9 That many parts of India, such as, parts of Himachal Pradesh, Northeast including Assam and some parts of central India appear to have been having village communes, where all forms of labour were valued equally, probably points to the nonexistence of any form of caste-like discrimination9a. Also, it may be worth noting that, castes like divisions are found in the history of most nations, in American continent, Africa, Europe or elsewhere in Asia, some societies having complex divisions and others’ relatively simple. Samurais and priests of early Japan and feudal lords of Europe are examples, the study of which will indicate existence of social stratification including hereditary progression, in the lines of caste system of India. Over and above this, a few among these could also boast of social inequalities manifested in institutions of slavery, a cruel practice, if not worse.

1.10 Even untouchability, which find no place in Indian history, is mentioned in the history10 of Herodotus, “the pig is regarded among them as an unclean animal….. are forbidden entry to any of the temples…. and no one will give his daughter in marriage to a swineherd or take a wife from among them so that swineherds are forced to intermarry among themselves.”

4 EVOLUTIONOF CASTE IN CHANGING SOCIAL ORDER

1.11 In short, Indian society, which welcomed the first invader, was having certain abstract notions of stratification, encompassing all aspects of life and society. Thus we have categories or different types of, men, women, guests, maidens, other beings like horses, dogs, cows, activities like sleeping, eating, other abstractions like friends, enemies and others with further subdivisions leading to myriad of esoteric classifications, each possessing unique functional properties; caste being one such subject of classification.
Such abstract nature of caste will be much clearer if we are to note that Hindu puranaic texts contain many instances where the moral worth of a person is seen as having been given greater emphasis compared to other attributes, say caste or family. For example, “truthfulness, generosity, restraint, tapas, constant adherence to dharma- these always lead men to fruition (of their goal) and not caste nor family”, or “Truthfulness, generosity, freedom from hatred, humility, kindness and tapas- he is known as Brahmana where all these are seen” and “if these are seen in a Sudra and they do not exist in a Brahmaa, the Sudra would not be a Sudra and the Brahmana would not be a Brahmana”12.

1.12 Before British: Early invasions to India, almost all, resulted in Islamic rule in India which created “a much stronger and much unified elite, which made it difficult for the ordinary masses to resist social changes, particularly in the realm of philosophical choice, religious pluralism and other personal preferences”9b. Notion of sexual prudery and gender separation infected Hindu households as well. “The overall effect of this cultural, military and political intercourse did not seem to have made any other revolutionary impact on Hindu society or alter the equitable social relations drastically”9b. Long before the arrival of Islam, new religious or reform movements within India opposed the caste system. In 6th century BC, Budhism started it. On casteism as a whole, how much of an effect Budhism could produce is not known. In fact the very nature of caste in the early days is not clearly known. For example, John W McGrindle mentions20, “According to Megastanes, race of India is divided into seven castes.
1 Philosophers- Only they are allowed to marry outside caste.
2 Husbandmen- They cultivate land
3 Herdsmen and hunters- They lead a wandering life
4 Tradesmen- They work in trades like weapon making
5 Fighting men
6 Overseers- They conduct general supervision and report to king
7 Assessors and councilors- They conduct justice, public matters etc
Also, in ‘Inscriptions of Nepal’21, castes are mentioned to be resulting from “the intermingling of varnas” and Vincent Smith22 writes “Though each caste has its own dharma, the conduct is less rigid than it has been since Moslem invasions”.

1.13 Effects of British ascendancy: In the beginning the British did no attempt to interfere with the caste system prevailing in India. In his observations on India, Karl Marx writes 14a”The village isolation produced the absence of roads in India and the absence of roads perpetuated the village isolation. On this plan a community existed with a given scale of low conveniences, almost without intercourse with other villages, and without the desires and efforts indispensable to social advance”17. The British, by bringing steam and railways into India initiated regular and rapid communication. Further introduction of roads breaking up the “self sufficient inertia” of Indian villages are some of the effects of British rule, though aimed at confiscating from India wealth in every possible form while “forbidding at the same time propagation of ideas which might not have been favorable for such ends. The modern industry resulting from railway system will dissolve the hereditary divisions of labor, upon which rests the Indian castes”14. But that did not take place, the changes in social atmosphere brought in by modern industry happened to get expropriated to suit the ordering of caste system.
In a paper ‘The Indian caste system and the British ethnographic mapping’15, Kevin Hobson says,” The caste system had been a fascination of the British since their arrival in India. Coming from a society that was divided by class, the British attempted to equate the caste system to the class system. As late as 1937 Professor TC Hodson stated that: ‘Class and caste stand to each other in the relation of family to species. The general classification is by classes, the detailed one by castes. The former represents the external, the latter the internal view of the social organization.’ The difficulty with definitions such as this is that class is based on political and economic factors, caste is not. In fairness to Professor Hodson, by the time of his writing, caste had taken on many of the characteristics that he ascribed to it and that his predecessors had ascribed to it but during the 19th century caste was not what the British believed it to be. It did not constitute a rigid description of the occupation and social level of a given group and it did not bear any real resemblance to the class system. However, this will be dealt with later in this essay. At present, the main concern is that the British saw caste as a way to deal with a huge population by breaking it down into discrete chunks with specific characteristics. Moreover, it appears that the caste system extant in the late 19th and early 20th century has been altered as a result of British actions so that it increasingly took on the characteristics that were ascribed to by the British.
1.14 “What the British failed to realize was that Hindus existed in a different cosmological frame than did the British. The concern of the true Hindu was not his ranking economically within society but rather his ability to regenerate on a higher plane of existence during each successive life”. He goes on to say “A census was undertaken in India, in 1872 for the first time, as one of the main tools used in the British attempt to understand Indian population. The census forced the Indian social system into a written schematic in a way that had never been experienced in the past. While the mughals had issued written decrees on the status of individual castes, there had never been a formal systematic attempt to organize and schedule all of the castes in an official document until the advent of the British census. The data was compiled on the British understanding of India”. Based on the census results, the British formed certain notions about Indian society and “these notions led to classification of intelligence and abilities based on physical attributes and this in turn led to employment opportunities being limited to certain caste groupings that displayed the appropriate attributes. Indians attempted to incorporate themselves into this evolving system by organizing caste ‘sabhas’ with the purpose of attaining improved status within the system. This ran contrary to traditional purpose of caste system and imposed an economic basis. With this, the relevance and importance of the spiritual, non-material rationale for caste was degraded and caste took a far more material meaning. In a sense caste became politicized as decisions regarding caste increasingly fell into political rather than spiritual sphere of influence. With this politicization, caste moved closer to class in connotation… In expropriating the knowledge base of Indian society, the British had forced Indian society and caste system to execute adjustments in order to prosper within the rubric of the British regime”. Thus we can see that caste was appropriated and in many respects reinvented by the British to create what it is now, with Brahman clearly at the head. That such was not the case in earlier times is mentioned, among others, by Dr Subhash Sharma16, who says that “the evolution of the society and customs were mainly due to individual and collective needs and choices. In addition, role and influence of various espoused or suggested proclamations such as, involving ‘varnasrama dharma’, manusmriti, on the development and progress of society at large was rather insignificant.”

5 CASTE- NATIONALIST MOVEMENTS AND BEYOND

1.15 History of India is replete with stories of social moderation efforts or other rearrangements in our multi faceted society. In the early times, if Budhism and Jainism heralded such efforts, we have Sikhism of relatively recent origin, all forerunners of social reformists. Raja Rammohan Roy, who could be called the father of Hindu reformation, gave leadership to Hindu revival in modern times. Dayanand Saraswati and Arya samaj, Annie Besant and Theosophocal society, Ramkrishna, Swami Vivekananda are some of those great ones who tried to cut through the sectarian lines of Indian religious organization, whose life and times certainly had been a source of inspiration for such efforts during freedom movement. However, those not belonging to upper castes, on becoming members realized that these organizations were primarily concerned with resurgence of Hinduism rather than reform as exemplified in the case of Swami Achyuthanand16, one of the important scheduled caste leaders of UP in 1920-30, who was a member of Arya samaj. The untouchables and other low castes resorted to ‘low caste movements’ of various nature, all of which can be broadly classified into two groups, those advocating resilience of hierarchy while adopting the basic notions of caste system or those suggesting adjustments in practice of caste system to include egalitarian precepts, an exception perhaps being found in Mahatmaji’s views on social struggle.

1.16 Mahatmaji’s views, about caste and the many facets of such social ‘ills’, underwent a gradual change, from 1920’s to late 1940’s.
- In 1920, he believed in the inevitability of caste system and that the many fruits that Indian society reaped over centuries were mainly owing to this. As examples, “I believe that caste has saved Hinduism from disintegration18a”, or, “In accepting the fourfold division, I am accepting the laws of nature.18b.”, can be quoted.
-By mid 20’s, he would start downplaying the inevitability of natural division, “In my conception of the law of varna, no one is superior to any other… A scavenger has the same status as a Brahmin18c”.
-As 30’s reached, he started observing that “unequal economic and social status perhaps existed, over the ages, and we have to enrich the inheritance left to us18d” and by 1935, “caste has to go. The sooner the public opinion abolishes it, the better18e”.
-In 1940’s he started expressing the importance of marriages between ‘atishudras’ and caste Hindus. From according “highest importance to marriages between atishudras and caste Hindus18f” and declaring that he will bless a couple “if the girl is from another community only18g”, he reached, by
-1945, understanding inter-caste as well as inter-religious marriage (if necessary, civil marriages), as a welcome reform. And by 1947, he welcomed “inter-religious marriages whenever it took place18h”
Had it not been for his assassination, we would have been witnessing Indian society, more as Gandhiji expressed on numerous occasions, “entire Hindu society converted to my view18i”.

1.17 The path caste took, during birth of free India and her democracy can be summed up thus: “Nevertheless, whether in relation to history of gender, the victimization of dalits, or the rise of anti Brahmin and backward caste politics, caste has worked to compromise the easy applications of national unity and civilized history. Caste has become the focus of progressive movements and of debates about the character of post colonial politics. It has also become the uncomfortable reminder that all claims about community are claims about privilege, participation and exclusion… caste has simultaneously preserved the patriarchy of pre-modern society and worked to sanction the continued oppression and exclusion of women in nationalist re-imaginings of the past. Caste may be the precipitate of the modern, but it is still the specter of the past19”.

6 CASTE – MY SIDE- A History of singularities

While studying the origins of caste system, an error seems to have crept into all the theories mentioned earlier, is that no theory, takes the philosophical plane of existence of caste (referring to caste as ‘varna’, an abstraction), into account. Though some authors23 tend to believe that castes are ‘hardened’ form of social classes (with implications such as ‘the upper caste might have been formed from the existing higher classes in society’), this is only a conjecture. Social classes are not founded upon occupational limitation where as castes certainly are. The class can be thought of as ‘presenting the external view of social organization’, caste, ‘the internal, abstract view’. Also, with further delineations, caste must have originated from varna as a mechanism for enabling selection of marriage partners. A ‘caste’ system on similar lines is followed among Australian aboriginals31, as described by Felix Keesing, where caste groupings play an important role in selecting partners in a way suitable for preventing progression of many problems where heredity plays a part. (For such a property of caste to manifest, it is necessary that caste is not fixed at birth as it is done in India)
An examination of our ‘puranic’ texts reveals that our forefathers spent much effort in ‘classification’ as a primary step in learning or understanding. Thus we have all objects, animate or inanimate, all actions and other abstractions classified into esoteric groups or subgroups, each having identifiable properties. Many methods are mentioned about stratification, say, of men and women into ‘varna’ based on intellectual orientation, of women into different types based on certain social nature (‘Kamasutra of Vatsyayana is a detailed treatise of this), of maidens, liars, thieves and other activities of war and love, to list a few. ‘Arthsastra’ of ‘Chanakya’ contain much dissertation on such topics.24
Nowhere in later writings or in social customs can these romantic delineations be seen as having been practiced widely. Of the myriad of themes our ‘puranic’ texts contain, caste alone became instituted in later social life, and this can be attributed to the ‘singularities’ in social evolution in India.

6.1 The first singularity is our philosophy or the way in which we understood our philosophy. For example, it treats possessions as bringing misery to man, leading therefore to a life, where, lesser the possessions, more desirable the life becomes. We, I think, do not realize that story of progress humans made so far is the story of our efforts, in adding new possessions, retaining a few or in the destruction of some. This did lead, as Marx observed earlier14, to formation of caste as the result of ‘the total lack of social intercourse’ compounded by ‘absence of desires and efforts indispensable to social advance’.

6.2 Next singularity is the attack by various invaders, almost all of them contributing to changes in social appearance of caste system, due to, their inability in appreciating Indian caste system as well as their ability in shaping caste system to suit the needs of governing the vanquished. British, though had to the longest lasting empire in India, did nothing to alter the existing caste equations or for social restructuring. This stands in opposition to their efforts in the direction of welfare of aborigines and their integration in another part of British Empire, Australia, even though “several of the tribes of southern India, who were of the race 'Homo
Dravida' (as he called it), had more in common with Australian aboriginals than their Aryan or high caste neighbours.”30
. For example, “When Dr Cecil Cook was appointed Chief Protector in 1927; he was wholly unsupportive of the missions. This was partly because of the poor conditions. More importantly, Cook had a similar vision of assimilation as West Australian Chief Protector A.O. Neville. Cook supported biological assimilation. Generally by the fifth and invariably by the sixth generation, all native characteristics of the Australian aborigine are eradicated. The problem of our half-castes will quickly be eliminated by the complete disappearance of the black race, and the swift submergence of their progeny in the white29.” The British view is better expressed thus, which perhaps explains why caste is still a problem in India, we are dutifully preserving a British legacy: “As Lord Dufferin put it: 'The diversity of races in India and the presence of a powerful Mohamedan community, are undoubtedly favourable to the maintenance of our rule...”31
6.3 Another singularity is Mahatma Gandhi. His views contained “I believe in ‘varnashrama’ of the Vedas which is based on absolute equality of status, notwithstanding passages to the contrary elsewhere”,…”The most effective, quickest, and the most unobtrusive way to destroy caste is for reformers to begin the practice with themselves…” and “The higher classes will have to descend from their pedestal…”18e. His advice to the lower caste was that they should “endeavor to merge themselves in the ocean of Hindu community” and “trust merit to command attention”18j. On another occasion, he is seen as proclaiming that reserving seats (for positions) is a dangerous principle. ”Protection of neglected classes should not be carried to an extent which will harm them...” and a person after he has secured a seat in an elected body should “depend upon his intrinsic merit and popularity to secure coveted positions”18k. To the castemen, on the other hand, his advice was that they “should prove that they had obliterated caste by their readiness to take up all those occupations which the ‘untouchables’ engaged in. Thus they should be ready to do a scavengers work….. The system of cleaning toilets would then be automatically transformed. In England real Bhangis were famous engineers and sanitarians... who had a perfectly clean way of dealing with human excreta… Needless to say, the Harijans will live in the same streets as others without any segregation…”.
Given that the prestige and influence Gandhiji had at that time, above mentioned changes would have taken place, leading to a social revolution as he would have been hoping for, resulting in a generation having, greater degree of cohesion in society, upper caste much less ‘upper’ and lower caste none ‘lower’ than any other, but for the social and political changes brought in when we introduced draft constitution with certain provisions, like reservation, for dealing with caste problem. Perhaps the very adoption of the idea of reservation without much debate25 by framers of constitution might have been hastened by the ‘preposterous’ suggestions of Gandhiji, the acceptance of which would certainly have resulted in them or their progeny (for sure) to have lost their exclusiveness (which caste status brought).

6.4 Communism presented another singularity. Our idea of caste and the way we found solutions to the problems it posed was altered much under the influences of communism and the revolutions in Russia and China.
(Communism in fact has more than on face. What we commonly see, a group of young (and may be not so young) men and women charged with ideals and the desire to see the ‘plight’ of many changed for the better, is one. A group (this may be a smaller one) of ‘intellectuals’ who manufacture propositions convincing enough to inspire, propel and guide them in their quest, making them move forward with incessant thrust, is another. The former is responsible for all that we welcome in a change, the alacrity, the selfless devotion of protagonists and absence of any motive or consanguineous profit other than for benefit of all. In short, in communism, those who follow the precepts are the best of humanity and the system hence produce good results even though they the philosophy is flawed. Also, as there isn’t any self interest, in communism, every effort yield favorable results, and that might be the reason that no one noticed the contradictions it contained, till communism collapsed.)
During communism in Russia26, the famines of 1921 and 1932-33 resulted in the death of more 5 million people each (Not counting additional deaths of 7-8 million people in the violence involved with ‘dekulakization’ during the period 1930-37)
In China, communists adopted genetic theory ‘lysenkoism’27, a modified form of Lamarckism, one of the main beliefs of which is that, like species help each other whereas unlike species do not, in guiding state farming policy. Accordingly, Mao ordered, organization of agriculture into collectives, introduction of certain farming practices like close planting, deep plowing, non use of chemical fertilizer etc, resulting in massive fall in agricultural output giving rise to a famine on a scale never before seen in China, in the period 1958-61, resulting in the death of a staggering 30 to 40 million Chinese.
In India, ‘lysenkoism’ and the possibility of inheriting environmentally acquired characteristics proposed by that theory perhaps supported the ‘reservationists’, as well as providing them with the necessary scientific foundation to ‘reservation’ as a panacea for all social inequalities. This also might have been the reason that none of the eminent reformers could see anything disadvantageous in it.

6.4 Next singularity, the most potent of all, is reservation or its euphemism, social justice. Wide acceptance of reservation as the panacea for all the ills associated with social stratification is, I think, due to the influence of communism, specifically, of the ‘scientific’ tenets propounded by Lysenkoism. The romantic thought, of lower caste brethren being uplifted enmasse by a small degree of social adjustment on the part of upper caste people must have influenced our constitution makers.
The desirable changes reservation system did bring in, and is doing so have been discussed at length, the general idea emerging from all these is that,
- Reservation system offers many advantages to the downtrodden, marginalized sections,
- The disadvantage of reservation system is that(mainly) opportunities are being denied for upper caste people, that is to say,
- Advantages of ‘reservation’ shall be to lower castes, and
- Disadvantages of ‘reservation’ shall be felt by upper castes
Such an idea is preposterous. Reservation system may be providing certain advantages to marginalized sections, however, some disadvantages also is their share. The most substantial of such disadvantages is that, it reduces or takes away opportunities of competition. As competition is removed from those from lower castes, they also are denied the fruits of competition, which, as is well known, is growth, intellectual et al. This is the most serious effect of reservation, and if we are also to consider the fact that, simultaneously, upper castes, due to greater opportunities of competition(or opportunities for sharper competition) made available to them as a side effect of reservation, are growing further in all faculties at a faster rate, the intellectual(for one) gap between lower and upper caste people will be on the increase, as generations go by, making it difficult to cohabit, at least as equal beings.
Even this could have been introduced in a manner befitting, or as an incentive to, growth. For example, ‘reservations’, if limited to jobs needing higher educational or academic performance shall be forcing lower castes to attain greater standards in learning. As mentioned earlier, the desire in providing an alternative to ‘wild’ suggestions of Gandhiji might have blinded all reformists from seeing any such possibilities.
In a study focusing on the ‘role of education in social mobility within the context of class structure’ by Hiroshi Ishida et al27, class origin (corresponds to respondent’s father’s class) and class destination (current class of respondent) are seen to have been influenced by
- Unequal access to education for different class origins. ‘two forms of educational advantage to sons of professional and managerial class(read upper castes), a better access to higher levels of education and an avoidance of lower levels’.
- Allocation of class positions(of destination) influenced by class origin. ‘Here also, highly qualified people have advantage in access to professional and managerial positions, but they also may be successful in avoiding manual positions. Conversely, poorly qualified are not only excluded from professional and managerial positions, they are more likely to be recruited to manual positions’. (Reserving such jobs for low castes is, adding fuel to fire)
Effect of education on class reproduction and mobility is remarkably uniform across nations with the exception of two socialist nations, namely, Poland and Hungary, of this study, where, more people can be seen as choosing manual and unskilled classes as destination, irrespective of class origin. In this, a major obstacle to equality of educational opportunity probably comes from the resistance of service class origin (e.g. managerial classes) to low qualifications, in addition to having access to high qualifications. While in case of lower classes, even when they were provided with access to high qualifications, as they are now, “the easy availability of low qualifications and the possibility of finding a livelihood effectively prevented them from reaching higher destinations”. Also, the low classes lack the ‘cultural traits’ necessary for entry into higher levels of education. Thus, as the cultural needs and desires, the fulfillment of which is the yearning of all who try to achieve better positions in life, are not fully developed in the case of lower castes, it is all the more important that this possibility of ‘finding a livelihood with low qualifications’ is eliminated, for education to be of use as an expedient.
6.5 Next and probably the last singularity may happen sometime in the future, many (or may be few) generations from today. In his well known essay on “Biological Possibilities for the Human Species in the Next Ten Thousand Years”28, JBS Haldane mentions of the possibility of human species “dividing into two or more branches for development of different human capacities. To me this is a terrible danger, as such species should fail to understand each other… and such misunderstanding can generate quarrels and even war.” This singularity though shall be befalling on all cultures, its effect on the already stratified (intellectually) Indian society shall be momentous, we might be on that ‘branch’ of the ‘species’ we wouldn’t want to be.

7 Caste – a summary
Caste is a relic of dark ages. It did not evolve into a modernized version naturally as we were not the real custodians of our society, having been under foreign rule for many years and those ruled over finding great use in caste, halting any such prospect. Other countries had their share of such customs which are even more shocking, like lynching or burning at stake, various entertainments of Roman Empire, all of which, evolved into something less obnoxious, as time went by. Even in recent times, some countries continued following many questionable practices and one such in the area of eugenics can be cited as example, where, compulsory abortion or other control over reproduction is imposed32.
Only one medicine has been tried so far towards demolition of caste and that is reservation. It is only logical to realize that as the cure did not work, we need to change medication.

17 This could explain how endogamy came to be instituted in Indian society. Absence of roads perpetuating village isolation, the only way to ensure continuation of species might have been adopted, endogamy. That such isolation affected our society, in more ways than one, can be seen, in the interesting fact that even in 19th century kerala, those who cross river ‘Bharatapuzha’ were liable for excommunication, or from observing that one of the significant sources of state’s income(in Kerala ) was tax imposed on lower caste men for sporting a moustache.

Shri Brajeshwar Prasad: “…The problems (the scheduled castes face) are primarily educational and of an economic character. They are of a cultural character. We want to raise the cultural level of these down-trodden and oppressed people. I do not see how their representation in the legislatures will in any way alter the material and the moral level of these people. Representations here and there will provide opportunities for a handful of leaders but it will not in any way materially alter their economic or their educational level. Better lay down in the Constitution that a fixed percentage in the budget, both Central and Provincial, shall be exclusively devoted for their welfare…I am quite clear in my own mind that by giving them a few seats here and there, their economic condition and their education level will in no way be improved”.

The Soviet Famines of 1921 and 1932-3
Ukrainian agronomist, Trofim D. Lysenko, well known for ‘scientific declarations’ regarding the perniciousness of genetics.
In the U.S.S.R. of the 1930s, Trofim D. Lysenko rose to considerable power by claiming that his version of genetics, rather than that of Mendel and Darwin, could assist in the development of socialist ideology. If each successive generation of citizens had to be educated in Marxist ideology, he claimed, the utopia they envisioned would take too long to be realized. Rather, Lysenko rejected Mendelian heredity as bourgeois, and interpreted Marx as stating that man and nature are improvable and perfectable. He claimed, for example, that a winter wheat could be changed to a spring variety simply by altering the temperature at which it was grown, and that, by similar means, he could change wheat into rye in one generation. Darwin’s struggle for existence, too, was dismissed as a bourgeois tool used to justify competition-based capitalist society. His erroneous assertions dominated Soviet biology for 30 years. He was eventually ousted, in 1965, due to rampant crop failures and shortages. Lysenkoism has come to represent the devastating consequences of marrying science to ideology. http://www.galafilm.com/afterdarwin/english/glossary/lysenkoism.html

30 Race, Caste and Tribe in Central India: the early origins of Indian anthropometry - Crispin Bates
http://www.csas.ed.ac.uk/fichiers/BATES_RaceCaste&Tribe.pdf

31 Cultural Anthropology Felix M Keesing,
The aborigines have an intricate classification system that defines kinship relations and regulates marriages, men and women grouped as Banaka, Burung, Karimera and Palyeri. Rules of marriage, descent, and residence determine how these sections interact: Karimera men must marry Palyeri women, and their children are Burung, Banaka men must marry Burung women and their children are Karimera and so on. Sons live in the same hordes as their fathers, so the composition of hordes alternates every generation. The complex system, by requiring each man to marry a woman from only one of the three possible sections, fosters a broad network of social relations and creates familial solidarity within the horde as a whole. Aborigines maintain elaborate systems of totemism (the belief that there is a genealogical relationship between people and species of plants or animals). They see the relationship between totemic plants and animals as a symbolic map of the relations between different people.

Vulnerable people bring out the kindness in every society and also the cruelty. Every so often, they become the object of practices so vile that they will cause people to recoil in horror across the centuries. One such practice is forced abortion, another is forced sterilization. The world has known for well over 15 years now that the Government of China routinely compels women to abort their unauthorized unborn children and that the Chinese men and women are often forcibly sterilized.

This paper argues that the dominant view of eugenics as morally and scientifically illegitimate is not tenable when it comes to the uses of compulsion, political motivation, and scientific acceptability. In spite of a general condemnation of eugenics, health authorities today are trying to prevent individuals with deviant behavior from reproducing or at least from rearing children.

Aluminium alloys casting Problems

Author: Rebecca

Aluminium alloys casting has played significant role in development of aluminium industry since its inception in late 19th century. The first aluminium products were castings such as utensils and decorative parts which exploited the novelty and utilization of new discovery. Those early parts quickly expanded to meet the requirements of a wide range of engineering specifications.

Alloys development and analyzation of physical and mechanical features gave basis for product development through the decades which followed. Casting systems were processed to increase capabilities of foundries in new commercial and technical uses. The system of melted metal processing, solidification, and property development has been advanced to assist foundry man with means of cost effective and trustable production of components which regularly meet specific needs.

Nowadays aluminium alloy castings are manufactured in hundreds of ways by all commercial casting systems including green sand, dry sand, composite mould, plaster mould, investment casting permanent mould, gravity casting, low-pressure casting and pressure die casting.

Material constraints which previously limited the design engineers alloy choice once a casting process was selected are continuously being blurred by advancement in foundry techniques. Similarly process selection is also less restricted these days. Like the many alloys previously thought to be unusable in permanent moulds because of their casting features are in production by that very process.

Melting and metal treatment:

Aluminium alloys may be melted in various ways. Coreless and channel induction furnaces, crucible and open-hearth reverberatory furnaces fired by natural gas or fuel oil and electric resistance and electric radiation furnaces are all in routine use. The nature of furnace charge is as different and important as the choice of metal casting operations. The furnace charge may differ from pre-alloyed ingot of high quality to charge made up of low quality scrap. Even under best melting and melt holding situation melted aluminium is at risk to these types of degradation.

a) With time at temperature, adsorption of hydrogen results in increased hydrogen content.

b) With time at temperature, oxidation of melt occurs.

c) Transient elements featured by low vapor pressure and high reactivity are reduced.

Turbulence or agitation of melt and increased holding temperature, significantly increase the rate of hydrogen solution oxidation and transient element loss. The mechanical properties of aluminium alloys depend on casting soundness which is highly influenced by hydrogen porosity and entrapped non metallic inclusions. Aluminium alloys casting and products manufactured by them are things of the future due to their cost effectiveness and lightweight.

The Importance of Iron Casting in the New Automotive Industry

Author: John Prince

One of the most efficient and economical means of shaping metal into a particular form is called casting- a process in which metal is heated to a molten state can be poured into a mold of choice and left to harden by foundry workers. Malleable iron is made from white cast iron by "cooking" it at temperatures from 1,500 too 1,850 degrees Fahrenheit over several days. This enables the iron carbide to break up, producing rosettes of graphite in the process. This particular iron is known for it's strength, pliability, shock resistance, and it's ability to be machined. This is one of the more popular ways of producing engine blocks, valves and iron ornaments among other items for the automotive and agricultural industries, plus many bits and pieces for the military.

Even on the most blustery winter day with every window open, casting iron is very hot, sweaty work. The temperatures of the raw materials heating up to an average of 2,850 degrees Fahrenheit (or more) can have quite the warming effect within the surrounding atmosphere.

In recent years, both the iron casting and the automotive industries have gone through some significant changes. For starters, the current higher than expected oil prices have created a demand for a smaller, lighter style of passenger vehicle. The result is a rise in car imports, leaving the Sport Utility Vehicle (SUV) market and it's heavy, automotive parts with a less than positive outlook. New fuel economy standards are expected to drive the renovation of iron blocks, suspension castings and carriers to aluminum in light trucks and increase the development of all lightweight metals.

2005 saw only a slight growth in the production of light vehicles, metal casting shipments rose almost 5% from 2004 to 2006 to over 14 million tons. This increase is expected to continue through the next few years to meet demand.

Many manufacturers in the United States are substituting plastics, ceramics, composites, lighter alloys, malleable iron in appliances, aerospace equipment and automotive components to help them compete in a global economy and to meet government regulations. Cast iron usage per passenger car and lightweight truck was approximately 600 pounds in 1980. By 1999, the usage had dropped to 325 pounds and industrial analysts estimated that usage could drop to under 200 pounds per vehicle within the next year.

All combined metal casting sales are estimated at $32.93 billion in 2005, and are forecast to increase to $37.67 billion by 2008, and then rise to $42.6 billion in 2015.
