• Business was established in 1985.
  • Our experience on machine doings goes back to the early seventies.
  • Over the years we have design and machine parts for the medical, laser, filtration, wafers, microwaves industries.
  • We can do work from concept to design to prototype into production.
  • When the equipment or tooling is not available we make it!
  • We made the equipment to do pulls for weld preps on 316L for sanitary filtration housings, shown on our home page.
  • We welcome short run productions and close tolerance manual machining.
