	Casting - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-21)
		Casting is a process by which a material is introduced into a mold while it is liquid, allowed to solidify in the shape inside the mold, and then removed producing a fabricated object, part, or casing.
		Cuttlefish casting using cuttlebone as a mould is a traditional casting method used by jewellers and silversmiths for small objects, especially in taking a copy from a metal original.
		Casting is a process by which a fluid melt is introduced into a mold, allowed to cool in the shape of the form, and then ejected to make a fabricated part or casing.

	Investment Casting
		Investment casting is also known as the lost wax process.
		Castings can weigh from a few grams to 35 kg (0.1 oz to 80 lb), although the normal size ranges from 200 g to about 8 kg (7 oz to 15 lb).
		Parts made with investment castings often do not require any further machining, because of the close tolerances that can be achieved.

	Investment Casting
		While investment casting are generally more expensive than forged parts or those parts produced by other casting methods, they make up for the higher cost by the reduction of machining which is achieved through the near net shape tight tolerances that can be held.
		Parts designed for the investment cast process may assist in reducing machining, and in many cases result in the casting of intricate shapes that may have otherwise required machining.
		Investment casting requires an individual pattern for each casting to be made.

	Investment Casting Process (Site not responding. Last check: 2007-10-21)
		Every casting produced by the process starts as a disposable wax duplicate (thus the term “lost wax”) that is injection molded in a permanent die built with allowances for the process.
		Since investment shells are cast unsupported, it is also necessary to have a fired strength capable of holding the weight of the metal cast, another consideration for determining the shell thickness.
		Prior to casting the shell is fired primarily to develop the fired strength of the ceramic (green or unfired shells have insufficient strength to contain the metal), and secondarily to remove any traces of the wax.
