Metal Injection Molding (MIM), sometimes referred to as powder injection molding, is a manufacturing process that combines the versatility of plastic injection molding with the material properties of metal. This innovative method is often used to produce complex-shaped metal parts with high precision.
The PM/MIM Sintering capacity of welle manufacturers including process, material, weight and size is listed as follows:
✧ PM/MIM Process: Vacuum Sintering, Mesh Belt type Sintering, Walking Beam Sintering
✧ PM/MIM Material: Low Alloy Steel, Fe2Ni, Fe4Ni, Fe8Ni, SS304, SS316, SS316L, 4605, 17-4PH, SS420,MPIF series Material, Tungsten Alloy, Tool Steel;
✧ Weight: 0.005kg – 0.05kg
✧ Size: 5mm – 200 mm
Manufacturing Process:
- Feedstock Creation: Metal powders are combined with a thermoplastic binder to create a feedstock material.
- Injection Molding: The feedstock is injected into molds using traditional injection molding equipment.
- Debinding: The molded parts are subjected to thermal or solvent-based processes to remove the binder.
- Sintering: The debound parts undergo a high-temperature sintering process, where metal powders fuse, resulting in a dense metal structure.
Materials: Metal Injection Molding supports a wide range of materials, including stainless steel, copper alloys, titanium, and more. Material selection depends on the desired mechanical properties and application requirements.
