WHY INVESTMENT CASTING? The investment casting process or lost wax process can produce the most intricate shapes in just about any alloy. In order to produce & machine these parts, you need to have in depth knowledge of the alloys and much experience...both of which Thompson Investment Casting possesses. There is no other metal working process that provides the design freedom to easily cast complex intricate shapes and assemblies as the investment casting process. The lost wax method out performs any other casting process when it comes to superior surface finishes especially when compared to sand casted, forged or welded fabrications. Some specific benefits are: Reliability The investment casting process provides reliable process controls and repeat ability that are maintained from casting to casting. Tolerances Tooltech Engineering routinely holds to tolerances of ± .005”. This is not always possible with other types of casting processes. Amortization L...
