Metal injection Molding (MIM) is the injection of the plasticized mixture of Metal powder and its binder into the model.
It is a mixture of the selected powder and binder, and then the mixture is pelleted and injected into the desired shape.
The polymer contributes to the uniformity of forming, cavity filling and powder loading by characterizing its viscous flow to the mixture.
After forming, the binder is eliminated, and then the degreasing billet is sintered.Some sintered products may also undergo further densification, heat treatment or machining.
The sintered products not only have the same complex shape and high precision as those obtained by injection molding, but also have similar physical, chemical and mechanical properties as forgings.
This technology is suitable for mass production of small, precise, complex three-dimensional shape and metal parts with special performance requirements.
