Metal Injection Moulding, or “MIM”, enables the production of small components in steels, stainless steel, tool steels, Invar & Kovar. Complex shapes, close tolerances, smooth surface finish and fine detail can be achieved with metal injection mouldings.

Metal injection mouldings are ideal for small parts with intricate features where good mechanical properties are required. Metal injection mouldings can be treated like any other metal - MIM parts can be bent, riveted, welded, heat treated etc.
