PTFE is nearly inert to everything and nearly frictionless — and nearly impossible to hold tight if you machine it like a metal. It is soft, it creeps under load and it moves with temperature, so precision PTFE is a measurement-and-fixture problem before it is a cutting problem.
Sharp tools, minimal clamping stress and heat control — PTFE deforms if you treat it roughly, at any temperature.
We quote achievable tolerances honestly: PTFE moves with temperature and load, and pretending otherwise produces scrap.
Chemical, insulating and low-friction components for aggressive process environments.
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Material | PTFE (virgin and filled grades) |
| Typical tolerance | Material-dependent — quoted per geometry; filled grades hold tighter |
| Temperature capability | Continuous service ~260 °C |
| Character | Ultra-low friction · chemically near-inert |
| Processes | CNC milling, turning, Swiss-type |
| Filled grades | Glass, carbon or bronze fill for stability |
| Prototype lead time | Typically 5–10 working days |
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
