CNC Machining with PEEK and Other HighPerformance Plastics

In the demanding world of precision manufacturing, material selection is often the defining factor between component success and failure. While metals have traditionally dominated, highperformance plastics like PEEK, Ultem (PEI), PPS, and PSU are revolutionizing industries by offering a unique combination of properties that are unattainable with metals alone. For businesses seeking reliable, hightolerance components, CNC machining these advanced polymers provides an unparalleled solution.

PEEK (Polyetheretherketone) stands as a flagship material in this category. Its exceptional performance profile includes outstanding thermal stability, continuously operating up to 250°C (480°F), and remarkable chemical resistance, even against harsh solvents. Crucially, PEEK boasts high strengthtoweight ratios and is inherently biocompatible (PEEKOPTIMA), making it a premier choice for aerospace, automotive, and critical medical implants. Similarly, Ultem (PEI) offers high strength and rigidity at elevated temperatures, along with inherent flame resistance, making it ideal for aerospace interiors and sterilizable medical devices.

The precision of CNC machining is perfectly suited to unlock the potential of these sophisticated materials. Our stateoftheart CNC facilities specialize in handling the specific challenges of highperformance plastics. We understand that these materials require precise tooling geometries, optimized feed rates, and dedicated cooling strategies to prevent melting, internal stresses, and delamination. This expertise ensures the production of components with impeccable surface finishes, tight tolerances, and preserved material integrity.

The benefits for your projects are substantial. Components machined from PEEK and its counterparts are significantly lighter than metals, contributing to fuel efficiency in automotive and aerospace applications. Their selflubricating properties reduce friction and wear in bearings and seals, while their excellent electrical insulation ensures reliability in electronics. Furthermore, their corrosion resistance eliminates the need for additional coatings or treatments, reducing longterm maintenance costs.
