Surface Finishes

Our metal injection molding process produces components with densities that are generally equal to or greater than 97% of theoretical wrought material densities.

  • The high densities result in as-sintered surface finishes that are typically 32 uin Ra.
  • With the addition of secondary operations such as tumbling, grinding, and polishing, surface finishes better than 16 uin Ra can be achieved.
  • Our MIM materials can be readily plated or surface treated with standard processes used on wrought materials with no need for special surface preparations.
  • Examples of surface treatments offered are: electroless nickel, chrome, electroless nickel Teflon, black oxide, passivation, and PVD treatments.
