HPP plastic machining: a DEMGY solution for your high-performance plastics

In industrial sectors where performance cannot be compromised - such as aeronautics, space, defense, electronics, medical and automotive - high-performance plastics (HPP) have established themselves as a reliable, long-lasting alternative to metals, thanks to their excellent mechanical, thermal and chemical resistance. Thanks to their excellent mechanical, thermal and chemical resistance, these plastics are indispensable.
DEMGY's expertise in plastic machining enables us to transform these advanced materials into complex, high value-added technical parts.

Why call on DEMGY to machine your machined plastics?

As a trusted industrial partner, DEMGY offers a complete solution, from the supply of materials to the finished part. Our machining centers are equipped with the latest CNC controls, enabling us to produce high-precision parts that respect the mechanical properties of each polymer.

1. Recognized technical expertise

Machining HPP engineering plastics requires perfect mastery of the material's specific characteristics. DEMGY processes PI (Vespel), PEEK, PAI, PCTFE, PTFE, PVDF or FEP with the utmost rigor, ensuring parts that meet the most stringent industrial requirements. Thanks to perfect dimensional stability, even over a wide temperature range, our parts guarantee optimum reliability in extreme environments.

2. Reduced production times and costs

Subcontracting machining directly to DEMGY enables you to reduce cycle times, optimize your purchasing and simplify the supply chain. We deliver machined plastics ready for integration, whether in prototype, small, medium or large production runs.

3. Quality control and traceability

Our processes include rigorous dimensional control at every stage. All materials and machining operations are traced, ensuring a high level of conformity and repeatability.

4. Industrial flexibility

DEMGY adapts to your custom projects, however complex, by offering you the most comprehensive range of HPP plastics on the market. Our in-house capabilities cover all sectors, from aeronautics and medical devices to high-temperature industries and corrosive environments (chemical resistance).
