Features

Our MIM powders have the characteristics of low oxygen content, regular morphology, high tap density, stable particle size distribution and chemical composition. The maximum weight of 5 tons per batch is convenient for customers to use. The advanced MIM evaluation laboratory can fully guarantee the consistency of product quality, and the product access to the customers recognition.

Typical Applications

MIM powder is mainly used as raw material for metal injection molding（MIM） to make various small parts with complex structures，such as mobile phone SIM card slot, smart electronic watch shell and other products.
