MachMaster provides high-precision CNC machining services for PEEK components, delivering exceptional strength, thermal stability, and chemical resistance. PEEK is the material of choice for demanding aerospace, medical, and industrial applications.
Material Description
PEEK (Polyether Ether Ketone) is a high-performance engineering thermoplastic renowned for its outstanding mechanical properties, chemical resistance, and ability to perform at elevated temperatures. It offers a unique balance of strength, stiffness, and dimensional stability.
Advantages of PEEK
- Excellent strength-to-weight ratio
- High thermal stability (up to 260°C continuous use)
- Outstanding chemical and wear resistance
- Good machinability for complex, tight-tolerance parts
- Low moisture absorption and dimensional stability
Wide Application of PEEK
PEEK is widely used in environments requiring extreme mechanical and chemical performance. Common applications include:
Aerospace components and turbine parts
Medical implants and surgical tools
Semiconductor manufacturing parts
Automotive engine components and seals
Industrial valves, pumps, and insulating parts
