The ancient industrial fabrication process of lost-wax casting where beeswax was primarily used, slowly and gradually evolved into investment casting. Investing casting in its most primitive form has been used since millenniums for casting or forming patterns. Presently, superior grades of waxes, specialized alloys like brass, bronze, and carbon steel, and refractory materials are used in aerospace casting and medical investment casting. The benefits of investment casting lie in that the procedure allows for the production of components that are precisely shaped, extremely versatile, have high tolerance threshold, and continue to remain serviceable for years.
Aluminum casting process used by different manufacturing and fabrication units enable the producing of casted forms or parts with enhanced physical attributes ensuring impeccable end-product performance. Aerospacecasting India method or mechanism has to go through a chain of stringent quality control checks throughout the fabrication process. This is to make sure that the casted patterns conform exactly to the original layout or design of the components before the same are shipped. The process of investment casting also finds widespread applications in the pharmaceutical/healthcare industry.
Medical casting procedure is harnessed extensively for manufacturing components of a variety of diagnostic equipment. This process entails x-ray examination, ‘chemical and physical testing’, and ‘fluorescent penetrant investigation’. Aerospace investment casting is chiefly exploited for the fabrication of turbine blades having sophisticated shapes and cooling structures.
Investment casting also finds applications in the firearm and defense industries for the production of firearm triggers, hammers, and receivers, and numerous other parts with a high degree of precision. Dentists, especially orthodontists who were devoted to making perfect dental inlays and crowns popularized investment casting as a fabrication procedure to be heavily used in aerospace, medical, military and automotive industries, although unwittingly.
