Powder Injection Moulding (PIM) is a technology of fabrication based on mixing ceramic or metallic powder with a polymer system. The feedstock obtained is injected in a mould, getting a part called «green part», which has a elevated content of polymers (around 50 vol.%).
This parts are processed in a furnace where the polymer system is eliminated, obtaining a very porosity part.
After that, sintering stage developed in a furnace allows the part to be full density, obtaining the final parts.
