Polymers move differently under the tool
Engineering plastics bring chemical resistance, low friction, and electrical insulation — but they flex, melt, and stress-relieve in ways metal doesn't. We manage heat, stress, and work-holding so polymer parts hold tolerance and stay flat.
Polymers we machine
PEEK for high-performance medical and semiconductor work, Delrin/acetal for precise low-friction parts, UHMW and nylon for wear components, plus PTFE, polycarbonate, and others.
- PEEK, Delrin (acetal), UHMW, nylon, PTFE, polycarbonate
- Medical, semiconductor, and industrial components
- Stress- and heat-managed machining for flatness
- Tight tolerances with clean finishes
Built for semiconductor work
Fab and semiconductor-equipment parts put polymers in environments most plastics can't survive: aggressive wet chemistry, plasma, vacuum, heat, and processes where particles and outgassing are failure modes. We machine the full family of semiconductor-grade polymers — wafer-handling components, CMP retaining rings, test sockets and handler fixtures, wet-bench and chemical-delivery hardware, chamber components, and robot end effectors — with the stress- and heat-managed machining that keeps them flat, dimensionally stable, and clean.
- PEEK — wafer handling, CMP rings, test sockets; strength at temperature
- Vespel® (polyimide) — plasma and vacuum chambers; high temperature, low particulation
- Torlon® (PAI) — high-strength fixtures and wear components
- Ultem® (PEI) — low-outgassing fixtures and electrical insulation
- PPS (Techtron®) — chemical and plasma resistance in process environments
- PTFE (Teflon®) — wet-process and chemical-handling components
- PFA — ultra-high-purity wet-bench and chemical-delivery hardware
- PVDF (Kynar®) — ultrapure-water and chemical-distribution systems
- PCTFE (Kel-F®) — near-zero outgassing and moisture absorption; dimensional stability
- Polypropylene & polycarbonate — wet benches, tanks, guards, and viewports
- Static-dissipative / ESD-safe grades (Semitron®-type acetal, PEI, and PEEK) — test handlers, end effectors, and anywhere static is a defect
