The MIM process starts with the feedstock which is a powdered material composed of metal and thermoplastic binders that will be extruded in the injection machine
The feedstock is injected into the mold cavities in the injection molding machine
The molded part is called green part
A green part is about 20% bigger than the final product
Runners and gates are recycled minimizing material waste
At this stage the feedstock binder is virtually eliminated.
We use two different binder systems PP wax and Poliacetal/Poliolefina.
After the debinding process ends, the part is described as the “brown part”.
