Injection molding of high-performance polymers: DEMGY Normandie's expertise

In high-tech sectors such as aeronautics, electronics, medical technology and the automotive industry, material performance is a strategic priority. Injection molding of high-performance plastics (HPP) offers a reliable industrial solution for the production of complex, durable and precise parts. DEMGY Normandie has established itself as an industry leader thanks to its expertise in technical polymers and their specific processing requirements.

Why choose DEMGY to mold your HPP parts?

As an expert in the shaping of high-performance polymers, DEMGY offers a complete industrial solution: from the choice of material through to the ready-to-use injected part. Our fleet of injection presses, dedicated to technical polymers, enables us to produce high value-added parts, for use in even the most extreme conditions.

1. Expertise in the most demanding HPP polymers

Our teams work with materials such as PEEK, PPS, LCP and PPA, all recognized for their dimensional stability, thermal and chemical resistance, and excellent mechanical behavior. Thanks to high-precision tooling and the control of molding parameters, we guarantee injection-molded parts that meet the strictest tolerances.

2. Reduced time-to-market

By integrating all stages - design, tooling, injection and finishing - at our Normandy site, DEMGY enables you to be more responsive. Rapid prototyping, pre-production or mass production: we adapt our production to your industrial production rates.

3. Quality, traceability and reproducibility

Our quality approach guarantees complete material traceability (material, batch certificates), systematic dimensional control and process repeatability. This enables us to deliver compliant injection-molded parts, ready to integrate your critical sub-assemblies.
