SERMATEC innovates with DeepTech Plasma Electrolytic Polishing (PEP) technology

Surface finishing is often a bottleneck in production: long cycle times, unpredictable reproducibility, pre- and post-treatment, complex geometries that are difficult to process, not to mention CSR constraints related to acid baths.

Our technology meets the industry’s critical needs in terms of finish quality, environmental responsibility, and automation, while handling complex geometries that are inaccessible to conventional processes.

We are industrializing this disruptive technology that turns your challenges into opportunities: Electrolytic Plasma Polishing (EPP).

In concrete terms, how is it different?

<✅ Mirror finish (Ra < 0.05 µm) in 30 seconds to 3 minutes depending on the material.

✅ Processing of complex geometries: internal channels, parts produced using additive manufacturing.

✅ No toxic products: neutral aqueous electrolytes, Green & Safe ♻️.

✅ All-in-one process: cleaning, degreasing, polishing, and deburring in a single step.

✅ Guaranteed repeatability: no recalibration, a single tool for all part shapes.
