CNC Machining in PTFE Material
We specialize in PTFE precision machining services and PTFE CNC machining parts, delivering high-quality custom PTFE parts and Teflon CNC machined components for prototypes and low-volume production. Our advanced equipment and optimized processes ensure machined PTFE parts meet tight tolerances with excellent surface finishes, including complex shapes and fine details.
Due to PTFE’s softness, high thermal expansion, and low thermal conductivity, machining PTFE presents unique challenges such as deformation and tool gumming/smearing. At Jiangzhi, we overcome these challenges through our expertise in CNC machining services. Utilizing specialized tools, precise cutting parameters, effective chip removal, and advanced cooling techniques, our PTFE CNC machining service consistently delivers reliable, high-quality custom Teflon parts and machined PTFE parts that meet stringent quality standards.

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 |
