History of Lost Wax Investment Casting
The process of manufacturing Lost Wax Investment Castings goes back several thousand years to Mesopotamia and Egypt.
Investment casting is an ancient art, but a young industry. With its roots in ancient Mesopotamia and Egypt, its commercial life began during World War II when military demands were overtaxing the machine tool industry. The shortcut discovered for the many complex parts with smooth surfaces, accurate dimensions and fine detail was borrowed from the techniques used by jewelers and the dental industry to meet the sudden demands of Industrial America at war.
In the 1950's, leaders in the industry saw the need for standardization and for providing information on what a user can expect from an investment casting. The Investment Casting Institute, the Society of Automotive Engineers (SAE), the American Society for Metals (ASM), the American Society for Testing and Materials (ASTM), the American Iron and Steel Institute (AISI), the National Institute for Standards and Technology (NIST), the Association for Non-destructive Testing (ASNT), and the American National Standards Institute (ANSI) have all been instrumental in establishing standards for investment castings and the metals used in them. The military and individual company specifications with which foundries are so familiar are now being replaced by ASTM and AMS specs, simplifying the maze we have faced and making possible buyers enhanced confidence that the part they order is the casting we ship.
