Cold forming of metals
From prototyping to industrialization
Our engineers specializing in materials science, mechanical design and process engineering support you in the development of all parts, from simple components to complex assemblies. They rely on our additive manufacturing and 3D printing prototyping processes to ensure rapid validation of designs and accelerated industrialization.
This co-engineering process allows us to anticipate the transformation technologies best suited to your part type and production volumes. Our portfolio of varied and complementary processes guarantees you an optimized mass production. Our components are intended for the automotive, aeronautics, electrical engineering and medical industries.

Complementary processes
Cold forming, machining, cutting, assembly and injection
We are specialists in cold forming and polymer overmolding of metal parts and electrical contacts based on copper alloys. Cold forming is a metal deformation process that enables obtaining parts in tube and wire, rolled parts, as well as all types of springs. Stamping is another of CGR's key skills, employed in all of our 20 plants in 8 countries. This press-cutting process, in combination with plastic overmolding, allows us to obtain parts such as connectors without welding. We also manufacture our own stamping tools.
The individual components we design and produce are then sent to our automated assembly lines to form complete subassemblies.
