MIM (Metal Injection Molding) combines the technologies of thermoplastic injection molding and powder metallurgy to produce complex-shaped, high density, high performance metal parts.
1. Best applied to small parts (typically less than 100 grams)
2. Offers lower cost solution
3. Improved mechanical properties
MIM mainly materials
Material System | Material composition | Typical applications |
Low alloy steel | Fe-2Ni, Fe-8Ni | Automobile, Machinery, ect |
Stainless steel | 316L, 17-4PH, 420, 440C | Medical equipment, Clocks, ect |
Carbide | WC-Co | Various tools, Watches, ect |
Ceramic | Al 2O3, ZrO2, SiO2 | IT electronics, Daily necessities |
Heavy Alloys | W-Ni-Fe, W-Ni-Cu, W-Cu | Arms industry, communications |
Titanium | Ti, Ti-6Al-4V | Medical and military structural parts |
Magnetic Materials | Fe, NdFeB, SmCo5, Fe-Si | Magnetic properties of various components |
Tool steel | CrMo4, M2 | Tools |
How MIM Works
The MIM process combines the design flexibility of plastic injection molding with the strength and integrity of wronght metals to offer cost effective solutions for highly complex part geometries.
The MIM process is typically explained as four unique processing steps (compounding, molding, debinding and sintering) to produce a final part that may or may not need final finishing operations
