What We Machine for Wear and Friction Applications
Materials for Wear-Resistant Plastic CNC Machining
Selecting the right polymer and grade is critical to wear life, PV limits, temperature resistance, chemical exposure, moisture behavior, and dimensional stability. We machine a wide range of wear-optimized plastics and can advise based on your application and budget.
UHMW-PE (Ultra-High-Molecular-Weight PE)
Very low friction, outstanding sliding wear and abrasion resistance. Common in conveyors, packaging, food-contact wear strips and guides. Excellent impact resistance; moderate temperature capability.
POM/Acetal (POM-C/POM-H)
Low friction, good dimensional stability and machinability. Ideal for bushings, gears, and precision wear components. Low moisture uptake compared with Nylon; consistent tolerances.
Nylon (PA6, PA66, Cast PA6G; oil-filled, MoS₂-filled grades)
Good wear and strength; self-lubricating options available. Widely used for gears, rollers, and wear pads. Note moisture absorption; design for dimensional changes if unfilled.
PET (PET-P)
Hard, wear-resistant, and dimensionally stable. Excellent for precision wear parts, cams, and low-moisture environments.
PEEK (unfilled and bearing grades with CF/graphite/PTFE)
High temperature and chemical resistance with excellent wear. Bearing-grade PEEK offers very low friction and high PV capability. Used in pumps, valves, semiconductor, aerospace, and high-load applications.
PAI (Polyamide-imide, e.g., Torlon-type grades)
Exceptional high-temp wear, stiffness, and dimensional stability. Suited for extreme PV, tight tolerances, and high-speed applications.
PPS (bearing/filled grades)
Low moisture absorption, chemical resistance, and good wear. Stable at elevated temperatures for electrical and pump components.
PTFE (filled grades: glass, carbon, graphite)
Ultra-low friction and dry-running capability. Ideal for seals, valve seats, and sliding interfaces; lower load capacity unless filled.
Additional Options
HDPE, PVC, ABS, PC, PMMA, PPSU, PSU, PEI, PVDF, PBT, and reinforced/antistatic/conductive/flame-retardant grades as required. FDA/food-contact and ESD-safe options available.

Design Tips for Wear-Resistant Plastic CNC Parts
- 💡Choose materials with the right PV capability; consider filled grades for higher load/speed.
- 💡Use generous radii and avoid sharp corners at load transitions to reduce stress and wear.
- 💡Allow for thermal expansion and (for some plastics) moisture uptake in fits and clearances.
- 💡Specify datum schemes and realistic tolerances for the operating environment.
- 💡For dry-running interfaces, consider polished or finely machined surfaces and rounded edges.
- 💡Avoid unnecessary thin walls; stiffness helps maintain alignment and contact geometry.
- 💡Where possible, design replaceable wear inserts to simplify maintenance.
Frequently Asked Questions
Which material is best for my application?
It depends on load, speed, temperature, lubrication, chemicals, and life target. We commonly recommend UHMW-PE for low-friction guides, POM or PET for precision wear parts, Nylon (filled) for gears and rollers, and bearing-grade PEEK/PAI/PPS for high PV or high temperature.
Can you replace metal wear parts with plastic?
Often yes—plastics can lower friction, reduce noise, and resist corrosion. We evaluate loads, temperatures, and expected deflection to ensure a viable substitution and may recommend filled grades for improved stiffness and wear.
How do you control deformation and dimensional stability?
We factor in material behavior, machining strategy, and inspection at controlled conditions. For moisture-sensitive materials, we consider conditioning and application environment in tolerance advice.
Do you provide prototypes before production?
Yes. We support single-piece prototypes and low-volume builds prior to repeat production.
What inspection and documentation can you provide?
Dimensional inspection reports per your drawing and sampling plan; material certifications and compliance statements are available when supported by the resin/stock supplier.
What industries do you serve internationally?
Industrial equipment, automation, semiconductor, medical/lab devices, automotive, aerospace-related equipment, pumps/valves, food processing, and robotics/fixtures.
