What is MIM? What does MIM mean?

MIM, also known as metal injection molding (MIM), is a molding method that injects the plasticized mixture of metal powder and its binder into the model.

It is to mix the selected powder with the binder, then granulate the mixture and then inject it into the required shape. The polymer endows the mixture with its viscous flow characteristics, which contributes to the uniformity of forming, cavity filling and powder filling. After forming, the binder is removed, and then the degreased blank is sintered. Some sintered products may also require further densification, heat treatment or machining. Sintered products not only have the same complex shape and high precision as those obtained by plastic injection molding, but also have physical, chemical and mechanical properties close to those of forgings.

This process technology is suitable for mass production of small, precise, three-dimensional complex metal parts with special performance requirements.
