More and more applications are being discovered for this advanced processing technology everyday where there is a need to drive out cost out of a metallic product that has historically been machined. It is capable of producing high quality components although has its limitation on tolerances needing to be held, often overcome with some secondary machining. The base material fed into the injection machine, called feedstock, is made by mixing powdered metals with a binding material, typically plastic, and is then ground into granules or pellets to accommodate the injection machine. The metal/plastic pellets are fed into the injection machine, which heats the plastic enough to liquefy it sufficiently that the plastic/metal combination can be pressed into a mold. The result is called a green part. The green parts are then subjected to a heating process that leaches the binding material from the green part. The remaining powdered metal part is then heated until the metal particles adhere through a sintering process, a critical step in holding required dimensions.
