PTFE is one of the most chemically inert and friction-resistant plastics available.
Our CNC ABS Machining Capabilities
Processes
- CNC turning (ideal for rings, seals, bushings)
- CNC milling (complex blocks, manifolds, insulators)
- Threading, boring, pocketing
- Ultrasonic cleaning
- Assembly machining with inserts or bonded components
Tolerance Standards
- PTFE is soft and compressible, so tolerances differ from hard plastics:
- Standard: ±0.10 mm
- Precision: ±0.05 mm (depends on geometry and wall thickness)
- Surface finish: Ra 1.6–3.2 μm
Application
PTFE is widely used in industries requiring chemical resistance, electrical insulation, and low friction:
