MIM PROCESS

How Does the MIM Process Work?

01
Feedstock Preparation:
The first step in the MIM process involves preparing the feedstock. Metal powders are combined with a thermoplastic binder to create a homogeneous mixture. This mixture is then pelletized, creating granules that are ready for injection molding.
02
Injection Molding:
In this stage, the feedstock pellets are heated and injected into a mold cavity with the desired shape. The injection molding process gives the flexibility to create intricate geometries with tight tolerances.
03
Debinding:
After the injection molding, the green part contains both the metal powder and the binder. The next step is to remove the binder through a debinding process, leaving behind a porous structure known as a brown part.
04
Sintering:
The final step is sintering, where the brown part is subjected to high temperatures in a controlled atmosphere. During sintering, the metal particles fuse together, resulting in a fully dense and high-strength metal component.
