Engineering plastics combine light weight, electrical insulation, low friction and chemical resistance. We CNC machine high-performance polymers — PEEK, PEI (Ultem), POM (Delrin/acetal), nylon, HDPE, UHMWPE, PSU, PAI (Torlon), polyimide and acrylic — for demanding technical applications.
PEEK offers high temperature and chemical resistance with excellent mechanical strength for medical, aerospace and industrial parts. PEI (Ultem) is a cost-effective alternative with strong insulation and flame resistance.
POM (Delrin) provides low friction, dimensional stability and easy machining for gears, guides and precision parts. Nylon is tough and wear-resistant for bushings, rollers and functional components.
Plastics expand more than metal and can absorb moisture, so we control temperatures, use sharp tooling and allow for thermal expansion and internal stress to keep parts stable.

Choose PEEK for high temperature/strength, PEI for insulation and value, POM for low-friction precision parts, and nylon for tough wear components. We can recommend a grade.
We account for each material’s expansion and moisture behaviour in fixturing and tolerances, and stress-relieve stock where needed.
Precision polymer parts can hold tight tolerances depending on the material and geometry; we define realistic, part-specific tolerances during DFM.
