Raw Materials



MIM combines the advantages of plastic injection and powder metallurgy.

It can produce high-strength metal parts with complex shape. MIM also suitable for automation and can produce huge quantity of small parts with precise dimension and complexshape, reduce complicated forms of traditional matal processing. As these advantages, MIM is competitive and being applied in some industry, such as machinery, electron, automoblie, clock, biotech, weapon and tool.

Metal injection molding (MIM) is a typical interdisciplinary product that integrates two completely different processing processes (plastic injection molding and powder metallurgy).This allows designers to break free from traditional constraints and obtain low-priced, profile-shaped stainless steel, nickel, iron, copper, titanium and other metal parts in a plastic-molded fashion, giving them greater design freedom than many other production processes.
