Machined PEEK


PEEK is a durable and stable polymer with excellent mechanical strength, low friction coefficient, and wear, chemicals, and radiation resistance. Its high melting point enables it to operate at temperatures up to 550°F (288°C). It is widely used in the aerospace, automotive, medical, and semiconductor industries due to its high-performance capabilities. PEEK can be easily machined into various shapes and sizes using milling, turning, drilling, and sawing techniques, making it ideal for applications that require tight tolerances and accuracy. It is a versatile material with exceptional mechanical and thermal properties suitable for various applications.

Why should you choose machined PEEK for your project?

PEEK is a high-performance thermoplastic with excellent mechanical, thermal, and chemical properties. It’s ideal for demanding aerospace, medical, and automotive applications due to its resistance to heat, chemicals, and wear. PEEK also has excellent dimensional stability, biocompatibility, and a high strength-to-weight ratio. It is quickly done to high tolerances, ensuring a precise fit for any application. PEEK is a durable and reliable material for projects requiring exceptional performance.

Finishes for machined PEEK

PEEK is a well-known material for its outstanding performance and versatility in strength, stiffness, chemical/thermal resistance, and overall durability. However, it is essential to consider that the finish of PEEK can significantly impact its overall performance, which is why choosing the right finish for your application is highly recommended. Several different finishes can be applied to it, including as-machined, polished, bead-blasted, or anodized, each with its unique properties and advantages. For instance, the as-machined finish can provide excellent accuracy and dimension stability. In contrast, the polished finish can offer a smooth and aesthetically pleasing surface for applications where visual appeal is essential. Ultimately, selecting an appropriate finish should be carefully considered based on the specific application and desired physical properties.
