Finishing for PTFE Parts
We ensure your PTFE parts are delivered with a flawless finish. Our team manually removes any burrs during the finishing process, leaving your components clean, smooth, and ready for immediate use.
Bead Blasting
Metals or plastics parts surface is left with a smooth, matte appearance, with no thickness removal specified.
As Machined
This finish retains visible tool marks and is suitable for both plastics. There is no specific thickness removed in this finish.
About PTFE Machining FAQs
PTFE (Teflon) is a highly durable, chemically resistant material with low friction, excellent thermal stability, and non-stick properties. It’s perfect for parts exposed to harsh chemicals, high temperatures, and wear conditions, such as seals, gaskets, bearings, and electrical insulators.
We can machine virgin PTFE, glass-filled PTFE, carbon-filled PTFE, bronze-filled PTFE, and other specialized formulations depending on your requirements for strength, wear resistance, or conductivity.
PTFE is highly durable with excellent resistance to chemicals, high temperatures, and abrasion. It can withstand temperatures from -200°C to 260°C and is ideal for harsh environments like aerospace, automotive, and chemical processing.
Yes! We can machine both internal and external threads in PTFE, as well as complex features such as grooves, slots, and precision holes, to meet your unique needs. Check out our thread standards
Prototype parts can be delivered in as little as 3 weeks, while larger production runs may take longer. We work closely with you to ensure fast and on-time delivery.
