Materials We Machine for High-Temperature Applications
We work with a wide range of heat-resistant and high-performance plastics. Common options include:
PEEK
Polyetheretherketone: High strength and dimensional stability; excellent chemical and wear resistance; suitable for elevated continuous service temperatures. Often chosen for aerospace, semiconductor, and high-load components.
PAI
Polyamide-imide: Exceptional mechanical strength and creep resistance at high temperatures; excellent for tight-tolerance parts under load.
PEI
Polyetherimide: High heat deflection temperature and electrical insulation; good for structural and electrical components.
PPS
Polyphenylene sulfide: Strong, dimensionally stable, and chemically resistant; suitable for precision parts in aggressive environments.
PPSU / PSU
Polysulfone family: Hydrolysis-resistant, stable at elevated temperatures; used in medical, fluid-handling, and thermal insulation parts.
PTFE
Polytetrafluoroethylene: Very low friction and excellent chemical resistance; useful for seals, bearings, and insulation operating at high temperatures.
PVDF
Polyvinylidene fluoride: Chemical resistance and good thermal stability; common in chemical-processing and fluid-handling components.
Notes: Grades, fillers (glass, carbon, PTFE), and brands impact machinability, stability, and performance. Continuous-use temperature varies by grade; we recommend sharing operating temperature, load, and environment details for precise material guidance.
If you require antistatic, conductive, wear-resistant, or flame-retardant grades, our team can propose suitable formulations and machining strategies.

Industries We Serve
Machining Capabilities and Tolerances
Core Operations
- CNC milling and turning
- Drilling, tapping, threading (metric/imperial)
- Counterbores, countersinks, slots, pockets, and complex features
- Deburring, edge breaking, surface finish optimization for plastics
Tolerances and Finish
We support tight tolerances on heat-resistant plastics, with achievable limits depending on material, geometry, and size.
- Stable materials (PEEK, PAI, PEI, PPS): Tight tolerances possible on well-supported features.
- Softer materials (PTFE): Tolerances adjusted to suit material behavior.
Surface finishes and feature integrity are managed with tooling, cutting parameters, and appropriate coolant/air strategies tailored to plastics. Share your drawing tolerances and critical-to-function dimensions—we will confirm achievable tolerances and propose refinements if needed.
