CNC Machining of PTFE (Teflon) Parts
We provide precision CNC machining for PTFE (Teflon), producing custom parts for prototypes and low-volume runs. Our team has hands-on experience making PTFE components with tight tolerances and smooth surfaces, even for complex shapes.
PTFE is soft and expands easily with heat, which can cause deformation and tool smearing. We handle these challenges using the right tools, precise cutting settings, effective chip removal, and proper cooling. The result is high-quality, reliable PTFE parts that meet your specifications.

PTFE Machining Properties
PTFE (polytetrafluoroethylene), widely known as Teflon, is a high-performance fluoropolymer composed entirely of carbon and fluorine atoms. It offers outstanding thermal stability up to 260°C, exceptional chemical resistance, a very low friction coefficient, and excellent electrical insulation. These properties make PTFE ideal for extreme environments where durability and reliability are essential.
CNC machining PTFE takes full advantage of these material qualities to create custom components for chemical processing, electrical insulation, medical devices, and low-friction mechanical parts. Its combination of chemical inertness, thermal endurance, and wear resistance ensures long service life, even in highly demanding applications.
| Tensile Strength, Yield (MPa) | Elongation at Break | Hardness | Impact Strength | Heat Deflection | Heat Deflection Temperature | Melting Point |
|---|---|---|---|---|---|---|
| 9–30 MPa | 200–400% | R55–R65 | 100–160 J/m | 100–120°C | 80–100°C | 327°C |
- The above parameters represent the baseline performance of the materials. Actual application should be dynamically optimized based on specific working conditions.
