Finishes for CNC Machined PTFE (Teflon®) Parts
PTFE resists most coatings due to its non-stick nature. While machining may leave burrs, we remove them to ensure clean, smooth parts. CNC machining allows for various surface finishes based on application needs.
Bead Blasting
Metals or plastics parts surface is left with a smooth, matte appearance, with no thickness removal specified.
As Machined
This finish retains visible tool marks and is suitable for both metals and plastics. There is no specific thickness removed in this finish.
Painting
Available for metals and plastics, this finish can be matte, gloss, or textured, with color matching possible.

What is PTFE (Teflon®)?
Polytetrafluoroethylene (PTFE), widely known by the brand name Teflon®, is a high-performance fluoropolymer valued for its exceptional non-stick and low-friction properties. Ideal for CNC machining, PTFE is commonly used in parts like bearings, bushings, and seals. It offers outstanding chemical resistance, operates in extreme temperatures from -200°C to +260°C, and provides excellent electrical insulation—making it a top choice for demanding industrial, chemical, and electrical applications.
