PEEK Machining Profiles
PEEK (Polyetheretherketone) is a high-performance thermoplastic prized for its exceptional strength, chemical resistance, and dimensional stability under heat and mechanical stress. Its unique machinability makes it an ideal material for mission-critical applications in industries such as semiconductor manufacturing, aerospace, medical devices, and high-performance industrial equipment. At Canyon Components, we support both ends of the manufacturing spectrum: we supply PEEK profiles—including tubes, rods, sheets, and blocks—for customers who do their own in-house machining, and we offer full-service CNC machining of custom PEEK parts built to exacting specifications.

PEEK Profiles for Machining
We supply high-quality PEEK profiles including rods, tubes, sheets, and blocks in a variety of grades such as unfilled, glass-filled, carbon-filled, bearing-grade, and medical-grade PEEK. These profiles are ideal for customers seeking to machine their own precision parts. Contact us for pricing and availability across different dimensions, tolerances, and specialty formulations. Our profiles are stress-relieved for dimensional stability and offered in options suitable for both high-temperature and cleanroom applications.
PEEK Profiles for Machining
Canyon Components offers a wide range of PEEK stock shapes ready for precision machining:
- PEEK Rods: Available in multiple diameters and grades, ideal for turned or milled components.
- PEEK Tubes: Suited for hollow parts, insulators, and lightweight structural components.
- PEEK Sheets: Useful for creating flat stock parts, gaskets, and custom panels.
- PEEK Blocks: Excellent for parts requiring deep milling or multi-axis machining.
All profiles are available in virgin and filled grades such as glass-filled, carbon-filled, and bearing-grade materials. We offer stress-relieved stock to minimize distortion during machining, and select profiles are cleanroom-compatible, making them suitable for semiconductor and medical applications.
Please consult a Canyon Components Engineer about your specific application and we will use our decades of experience to formulate a solution that fits your need.

Design Considerations
Machining PEEK requires attention to several key factors:
- Stress Relief: Always use stress-relieved stock to avoid warping
- Anisotropy: Consider grain orientation in extruded or molded profiles
- Thermal Expansion: Account for thermal growth in high-temperature environments
- Post-Machining Tolerance: Leave allowances for final conditioning, especially in tight-tolerance fits
- Our engineers are available to assist with design-for-manufacturing and material optimization.
Common Applications for Machined PEEK
PEEK's combination of thermal, mechanical, and chemical resistance makes it ideal for a variety of demanding applications:
- Semiconductor: Wafer guides, insulators, chemical-resistant components
- Aerospace: Thermal brackets, lightweight bushings, and sensor enclosures
- Medical Devices: Reusable surgical tools, housings, and sterilizable assemblies
- Industrial: Seals, wear plates, high-load structural components
