PEEK & Plastic Machining.
PEEK, Ultem, Delrin, PTFE, and nylon held to print across thousands of pieces.
Machined plastics move, flex, and heat up differently than metal. Holding tolerance across a production run takes the right fixturing, tooling, and stress control. We've delivered runs of 6,000 machined plastic parts to print, documented like our metal work.
What to expect.
- Tolerances
- ±.001" typical · tighter on stable features
- Volumes
- Prototype through 6,000+ piece runs
- Documentation
- Material certs, FAI, inspection records
- Grades
- PEEK (incl. medical grades), Ultem (PEI), Delrin / Acetal, PTFE (Teflon), Nylon, Polycarbonate, UHMW
Getting peek & engineered plastics right.
Stress and movement
Stress-relieved stock and staged roughing and finishing keep parts from moving after they're cut.
Fixturing
Soft, part-specific fixtures that hold plastics without distorting them.
Clean edges
Sharp tooling and controlled feeds for burr-free edges without melting.
- Medical device housings and components
- Insulators
- Wear pads and bushings
- Fluid manifolds
PEEK & Engineered Plastics questions.
Can PEEK hold tight tolerances?
Yes, with the right process. PEEK is relatively stable among plastics; we stress-relieve, rough, and finish in stages to hold tight tolerances.
Do you machine medical-grade PEEK?
Yes, with material certification and traceability through our FDA-registered quality system.
What's your largest plastic production run?
One of our largest single orders was 6,000 machined plastic components, all delivered to print.
