  • Superalloys: Haynes 25, Kovar, Invar, Inconel, Hastelloy, Cobalt Steels and Nickel Steels.

Specialties Include:

  • Contract Manufacturing for medical devices and parts
  • Drilling precision holes and small diameter holes
  • Precision Turning with Super Precision Lathes (0.1 micron resolution) for close tolerance parts
  • Machining with CNC ultra precision 5 axis applications
  • Machining Military and Aircraft parts

Critical parts for industry:

  • Complex, high-precision components maintained to tolerances of +/- 0.0001" (0.0025mm). We utilize CNC 4-axis and 5-axis milling as well as 3-axis turning.
  • Materials including but not limited to plastics, rubbers, ceramics, aluminum, steel, stainless steel, superalloys, titanium, and refractory metals.
  • Special operations such as tumbling, glass bead blasting, micro-blasting, polishing, riveting, and assembly.
  • Inspection of each part to ensure that every specification is met. We use a multi-step process, which includes hand gauges, CMM, optical comparators, and Go/No-Go gauges to create Inspection Sample Warrants to ISO and AS requirements.

Expert technical product design support:

  • CAD/CAM - from idea, drawing, Math Data (CAD files)
  • Upon request will recommend design enhancements for optimal-cost manufacturability.
  • Technical product-design support, non-disclosure agreements and confidentiality are standard practices.

A "one-stop shop" for turn-key solutions:

Protomatic usually responds to quotes within 24 hours.

We solve your toughest challenges dealing with innovation, new product development, production and emergency situations.

  • If cast parts are not available or if they are still in transit from an international supplier, we can rush billet parts to meet your pre-production or production needs.
  • We manage secondary operations such as anodizing, grinding, plating, welding, sandblasting, painting, electro-polishing, and dry film lubrication.
  • Program management of your job(s) handled from initiation to completion.
  • We deliver on time and actively seek out cost reductions.
