CNC Machining
PTFE (Teflon) is an engineering thermoplastic with outstanding chemical and thermal resistance and the lowest coefficient of friction of any known solid. We supply Teflon PTFE CNC parts across the UK, from single prototypes to production runs.
Although its mechanical properties are modest compared with other engineering plastics, its chemical resistance and high melting point make it extremely versatile. As a result it is often specified for chemical engineering, general machinery and electrical applications. Its quoted tensile strength of around 31 MPa gives a useful guide when sizing parts.
Parts are CNC milled or turned and available in white or black. Send us a STEP file and we will quote your Teflon PTFE CNC parts promptly, with UK-wide delivery. Finish options (as machined) can be confirmed when you order. Every order is checked against your drawing before dispatch.

Values shown are typical supplier figures for Teflon PTFE and may vary with stock condition. Please confirm critical properties before production.
PTFE machines easily but is soft and has low mechanical strength, so it can deform under clamping and cutting forces. It also expands considerably with heat.
PTFE is soft and expands considerably with heat, so very tight tolerances and thin walls are difficult to hold. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
PTFE is usually supplied as machined, deburred or bead blasted.
Typical uses include chemical engineering parts, general machinery, electrical applications and food industry parts.
PTFE has near-universal chemical resistance and very low friction, but it is soft. PEEK is much stronger and stiffer at high temperatures. Choose PTFE for seals, liners and low-friction parts, and PEEK for loaded parts.
The typical lead time shown for PTFE (Teflon) is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
