What is
Metal Injection Molding?

Metal injection molding uses a pelletized metal feedstock at high pressure and temperatures to form complex shapes that would normally be considered cost prohibitive. MIM is capable of producing features that cannot be achieved by investment casting, such as small holes, thin walls, and fine surface detail. Additionally, MIM parts have better strength, magnetic, and corrosion properties due to high density achieved when compared to conventional powdered metal, plastics and die casting. The process is sometimes referred to as Powdered Injection Molding (PIM).


  • Lower cost compared to CNC
  • Faster production and better feature detail compared to investment casting
  • Provides very accurate parts with tight tolerances
