Metal Injection Molding (MIM) combines the technologies of thermoplastic injection molding and powder metallurgy to produce complex-shaped, high density, high performance metal parts.
Best applied to small parts (typically less than 100 grams), the MIM process offers lower cost solutions for numerous applications compared to machining or investment casting, and improved mechanical properties compared to plastic injection molding or zinc die casting.
Design Freedom - MIM offers design flexibility similar to plastic injection molding. Geometrically complex parts that cannot be produced using the conventional powder metal processes without secondary machining are possible using the MIM process.
Reduced Assemblies - The MIM process can be used to combine two or more simpler shapes into a single, more complex component to minimize assembly costs.
Reduced Waste/Machining - MIM's capability to provide net shape components eliminates many secondary machining operations.
Improved Properties - MIM parts are typically 95% to 98% dense, approaching wrought material properties. MIM parts achieve greater strength, better corrosion resistance, and improved magnetic properties when compared to conventional powder metallurgy processes.
