The MIM Process of Three Steps

MIM process(http://www.zcmim.com/helps/mimprocess.html) requires three steps:

(1) In condition of heating, pressure, injection the mixture of powdered metal and thermoplastics (or other binder) into mold cavity (similar to thermoplastic injection molding).

(2) Removing binder by heating or melting, only the metal powder left.

(3) Sintering the metal powder. Sintering temperature should be lower than the melting point of metal, but enough to make metal powder combined into solid metal (actual solid metal density is more than 96%).
