The diversity of our application sectors and our position as leader in several high-tech markets enable us to offer a wide range of activities for machining and assembly operations and all the skills required for the design and production engineering of our products. Our complementary trades and our expertise and know-how combine in a team effort aimed at excellence.

Our production activities

Our flash-butt welding and rolling process and extensive expertise allow us to control the transformation process of our raw materials into precision parts for the most demanding applications.

  • At each stage of manufacture, we ensure the conformity of our parts, both in terms of dimensions and the validation of the structure of the materials by qualified personnel for the performance of non-destructive testing (magnetic particle inspection, ultrasound, dye penetrant testing, etc.). Our test laboratory also validates all mechanical properties (hardness, etc.). 
  • We ensure the conformity of the tracking file of each part in order to ensure the traceability of the product.
  • All our ISO, EN, IATF, NADCAP and customer qualifications enable us to guarantee the outstanding quality of our products and processes.
