Metal Injection Moulding (MIM)
At a glance
The MIM process, also known as Metal Powder Injection Molding or Metal Injection Moulding, combines injection molding with sintering technology.
The starting material is a feedstock of stainless steel powder (1.4404) and a thermoplastic binder. Components are formed from the feedstock through injection molding. The final product made of solid stainless steel is achieved by completely removing the binder through a chemothermal process, followed by the sintering process.
From granulate to finished component – The MIM process
1. Mixing and granulating feedstock:
The feedstock is created by kneading and heating a homogeneous powder mixture of metal powder in the corresponding alloy and thermoplastic plastic as a binder. After granulation, the feedstock becomes viscous and ready for processing.
2. Injection molding:
The feedstock is injected into a closed mold at high pressure and elevated temperature. The resulting green part possesses all the geometric properties of the final component.
3. Debinding:
Removal of the binder from the green part. What remains is a purely metallic but still open-pore component, called the brown part.
4. Sintering:
Sintering the brown part at high temperatures. The result: a precision-molded part with the desired geometric and mechanical properties.
5. Final Inspection:
Testing, examining, and evaluating. Comprehensive quality control in the MIM laboratory.
