The journey of advancement in
investment casting starts from the beginning of the last century and continues to meet the needs of designers and purchasing agents,from a host of industries,which are demanding more complex part configurations,more accurate dimensions,intricate designs,smoother contoured surfaces,and higher mechanical properties.
investment casting process makes use of an expendable pattern in the production of engineering products. It converts molten metal in a single operation to precision-engineered with a minimum wastage of material and energy and subsequent machining. It has a versatility approached by few other metal forming processes. Intricate or re-entrant contours can be incorporated. These features offer great freedom of design with the process. The versatility of the technique extends to materials,since virtually any alloy can be cast. The general situation in the global
investment casting industry is quite good at the moment.
investment casting market is continuously growing for the demand in increasing aerospace and automotive markets as well as spreading to the other general industrial sectors despite of the stiff competition from other manufacturing process. The rapid growth of markets in developing countries coupled with more than one-third global population around 6.5 bilion people continues to improve the future growth. In this century,precision
investment casting with respect to complex geometry as well as precious alloys like Ti,Zr,Co & Ni base alloys have a tremendous role for improving domestic as well as export market.
