What is Metal Injection Molding

Metal injection molding is a new type of powder metallurgy near-net forming technology that has been extended from the plastic injection molding industry.
In order to improve its performance, metal or ceramic powder can be added to the plastic to obtain products with high strength and good wear resistance. In recent years, this idea has evolved to maximize the content of solid particles and to completely remove the binder during the subsequent sintering process and densify the forming blank. This new powder metallurgy forming method is called metal injection molding.

First, the metal powder and the binder are selected according to the MIM requirements, and then the powder and the binder are mixed into a uniform feed at a certain temperature by a suitable method. After granulation, the molded product is subjected to degreasing After sintering the densification into the final product.
MIM products due to the complex shape, sintering shrinkage, most of the sintering is still completed after the sintering treatment, including shaping, heat treatment (carburizing, nitriding, carbon nitriding, etc.), surface treatment (grinding, Chemical plating, shot peening, etc.).
