Where we are picky about your finish

Welcome to Patmai


Patmai offers all your metal finishing needs from large production runs to small prototypes. We finish all types of material from softer silver, brass and aluminum to harder tool steel and stainless. We offer a variety of finishes from a coarse satin to a mirror-like finish.


Patmai was established in 1963 by Buddy Mattox with old school buffing and polishing back when buffing was a skilled trade. Bud retired in 1993 leaving the company to family and close friends. In 1993 after the take-over, Patmai changed its platform from polishing one or two types of metals to all types with a variety of finishes.

Through the years, Patmai has continued to grow and improve by keeping up to date with all new materials available, training and retaining skilled workers and producing quality workmanship. It is our goal to be efficient, cost effective and support our customers to the best of our ability.

  • 22 Buffing Stations
  • 10 Polishing Stations
  • 40-50 Employees
  • 2 Automated Buffing Straight Lines

Patmai is ISO 9001-2008 certified and committed to continuous improvement and customer satisfaction.


Many people ask how the name Patmai came to be. The original owners tossed all their daughters and wives names into a hat. The first name picked was Pat and the second, May. The ‘y’ in May was changed to ‘i’ and the company was named Patmai.
