CNC machining peek applications

PEEK has a wide range of applications in a number of fields due to its excellent resistance to high temperatures, mechanical properties, chemical resistance and other characteristics. CNC machining technology can realize high precision and repeatable processing of PEEK materials, to meet the requirements of complex geometries and tolerance limits.


Structural parts of aircraft and satellites, such as fuselage, tail, hub, gears and drive shafts, etc. The high heat resistance, mechanical properties and flame retardant properties of PEEK materials can maintain stable performance in extreme and harsh environments, ensuring the safety and reliability of aircraft.

Automotive Industry

Manufacturing of various automotive parts, such as engine components, sensors, seals, etc.. For example, PEEK seals and thrust washers are used for automotive transmission and clutch seals, PEEK worm gears are used for automotive seat adjusters, and PEEK vacuum pump rotors are used for automotive power brakes.

Medical Devices

PEEK’s good biocompatibility and mechanical properties, PEEK materials in the field of medical equipment manufacturing artificial joints, orthopedic implants, dental equipment and surgical tools, etc. PEEK’s X-ray transparency also makes it in the image detection and medical imaging equipment applications.


The high insulation and abrasion resistance of PEEK materials play an important role in the manufacture of electronic components, such as electrical contacts, insulated parts, sockets, cable insulators and so on.
