Advantages of MIM

  • It is process for high volume production in less time and reduced cost.
  • MIM can produce parts where it is difficult, or even impossible, to efficiently manufacture through other means of fabrication. It offers greater design freedom than many other production processes by freeing designers from the traditional constraints associated with trying to shape stainless steel, titanium, high and low carbon steel and tool steel.
  • MIM makes it possible to integrate and consolidate several components into a single molded piece—reducing the need to work with several manufacturers and decreasing processing and assembly costs.
  • Texture, knurling, threads, lettering, and company logos can all be incorporated into the mold which significantly lowers costs.
  • Metal injection molding eliminates inclusion defects which result from unwanted material such as slag or ceramic chips that get into the molten material caused by traditional casting. Also the large pores or gas pockets that often form during traditional casting are eliminated because the material fills the mold entirely.
  • Since the parts are made of metal or alloy powders, purity and corrosion resistance are significantly better than with cast and wrought parts. It eliminates all long and tedious elementary machining operations.
