Metal injection molding (MIM) is a powder metallurgy process used for manufacturing metal parts. Although MIM uses powder metal, it is nothing like conventional powder metal process. The metal powders used in MIM are 10-100 times smaller than in powder metal processes. Also, the end product of MIM is much higher in density (greater than 95% theoretical density). Unlike powder metal, products manufactured by MIM can be case or through hardened, painted, and drilled and tapped.

Metal injection offers the same benefits and features of plastic and rubber molding, but produces a much stronger end product. Metal injection molding can provide a substantial cost savings over conventional metal machining options. Applications for MIM parts include surgical tools, automotive locks and actuators, firearm components, computer hard disk drives, and electrical connectors.
