Mastery of Plastic Materials

Our expertise enables us to work with a wide range of technical plastic materials, each with unique properties suited to specific applications:

• TEFLON (PTFE - Polytetrafluoroethylene)

This material is renowned for its extremely low coefficient of friction and resistance to extreme temperatures (up to 260 °C), it also has very good electrical and dielectric properties. It is chemically non-reactive, making it ideal for applications in the medical and chemical fields, as well as for components requiring minimal lubrication. This is currently the material we use most often.

Applications :

Electronics: Cable insulators and electrical component insulation.
Aerospace: Connector insulators and protective materials for high-stress environments.
Aeronautics: Anti-friction components such as bushings or seals.

• POM, (polyoxymethylene)

also known as Acetal or Delrin (trademark): A high-performance thermoplastic with excellent mechanical strength and a low coefficient of friction. It offers outstanding dimensional stability, even in demanding environments, and resists many solvents and fuels. Usage temperatures range from -50 °C to +100 °C.

Quality Control and Durability

ISO 9001 certified, we place particular importance on quality through rigorous processes:

Use of statistical methods (machine capabilities: cm, cmk; process capabilities: cp, cpk).
Thorough unit inspection and sorting, performed manually and under binocular microscopes by experienced technicians to ensure maximum quality.
Adherence to tight tolerances, especially in aerospace applications (minimum of 3 hundredths; PEEK 2 hundredths).
Hot and cold washing of parts to ensure their stability.

Zero PPM is the goal we have set, and with 100% inspection guaranteed by a metrology department equipped with the best tools—Keyence devices, roughness meters, contour graphs, measurement columns, etc.—we are able to ensure full compliance of the produced parts, regardless of their technical requirements or specific tolerances.

Thanks to these state-of-the-art tools combined with the expertise of our skilled technicians, we identify and correct any potential deviations or variations in real-time. This rigor enables us to maintain a high standard of quality for our plastic parts, meeting the strictest standards of demanding sectors and fully satisfying our clients' expectations.

Furthermore, our processes include:

Deburring and manual polishing, ensuring the perfect finish of our parts.
Manual sorting of chips for recycling, maximizing their reuse.
