  • Our fully automated barrel plating lines were designed and built by the Whitaker Finishing’ technical staff.

  • Whitaker’s barrel lines are precisely controlled via our computer network system including auto-feed chemistry.

  • Stampings—Whitaker’s barrel design allows us to barrel plate stampings which may otherwise need to be rack plated.
