Metal Injection Moulding (MIM) process is an economically attractive method of producing large amounts of small and complex metallic parts.
This is achieved by combining the productivity of injection moulding with the versatility of sintering metal particulates. In MIM, the powdered metal is blended with a binder to obtain a feedstock. The binder imparts flowability to the blend at injection moulding conditions and strength at ambient conditions. After moulding, the binder is removed in a sequence of steps that usually involves solvent extraction and thermal pyrolysis. Once the binder is removed, the metal particles are sintered.
Accordingly, though the binder should not dictate the final composition, it has an influence on the process. Today, new local binder composition and its effectiveness as a binder system to all type of metal powder are the focus of many investigations.
