The basic process of metal injection molding (MIM) is:
First, the solid powder is uniformly mixed with the organic binder, and after granulation, it is injected into the mold cavity with an injection molding machine under heating and plasticizing state (~150℃) to solidify and shape.
Then use chemical or thermal decomposition to remove the binder in the molding.
Finally, the final product is obtained by sintering and densification.
