Teflon™ Machining Capabilities

Teflon Machined Part

Turned and milled Teflon part used in an agriculture pump. Machined from 2” thick plate, tolerances of +/-.002”, finish requirements for sealing surfaces, Tight bores for both press fits and function of moving parts.

Portland Precision is an industry leader in tight tolerance, high precision Teflon™ machining. Teflon™ is one of most common and popular engineering plastics, and we have the machining experience and expertise to produce top quality Teflon™ parts that match our customers’ designs and exceed their expectations.

We have a highly skilled staff and cutting edge CNC machining equipment, which enable us to create precision machined Teflon™ parts and components with tolerances of ±0.0005” or better. With our machining capabilities, even the most complex parts can be produced with perfect accuracy and repeatability from the first piece to the last. For prototype parts, full production runs with quantities in the tens of thousands, or projects that fall somewhere in between, our Teflon™ machining services are the ideal solution.

Machining with Teflon™                              

A modified formulation of PTFE (polytetrafluoroethylene), Teflon™ is famous for its extremely low coefficient of friction, and, thanks to this, has long been used as a nonstick coating for frying pans and other cookware. It also provides high temperature resistance, high chemical resistance, and high weatherabilty; compared to regular PTFE, it exhibits better dielectric properties, greater weldability, and greater load deformation resistance. Common applications for Teflon™ include semiconductor components, bushing, bearings, cable/electrical connectors, high temperature electronics components, gears, capacitors, electrical insulators, and other diverse products.

Beneficial Properties of Teflon™

  • Excellent dielectric properties
  • Chemically inert
  • High heat resistance
  • High chemical resistance
  • Extremely low coefficient of friction
  • Impervious to moisture absorption
  • Excellent machinability
  • Very good weatherability
  • Resists deformation under load

Teflon™ is a trademark of DuPont Co. There are other similar, but not identical, polymers that are also sold under the Teflon™ name. Similarly, there are variations of Teflon™ polymer that are chemically slightly different but offer essentially the same properties, by different companies and sold under different names. Portland Precision has the capabilities to machine all permutations of Teflon™ with equal quality and precision. We also provide high precision machining for various other exotic and engineered polymer materials. Contact us to discuss your project’s specific material requirements.
