Cold forming and overmolding

Springs, mechanical and mechatronic components


CGR specialises in the manufacture of springs, mechanical and mechatronic components, and complete sub-assemblies. With factories on four continents, we provide a local presence with global reach. CGR's teams and centres of excellence bring together a wide range of skills and technologies in cold forming and metal overmolding. Our customers around the world rely on our co-engineering expertise and our ability to produce a wide range of components.

Aerospace, automotive and beyond

From prototyping to mass production


For more than 50 years, CGR has been a recognised partner in the manufacture of custom springs, cold forming of metal components, mechatronic parts and metal-plastic sub-assemblies for the industry in general and for automotive and aerospace markets in particular. Our ability to meet both automotive production rates as well as the strict standards of the aerospace industry makes us the partner of choice for all manufacturing projects, whatever the sector.

 

From co-engineering to industrialisation

Expertise in metallurgy and production methods


Drawing on a vast pool of skills, qualifications and expertise, our engineers and operators respond to the most complex manufacturing projects. Our teams are organised into autonomous, agile production units, supported by centres of excellence. They share their knowledge of production methods, process engineering, materials science and quality control at every level of our international organisation. We produce our own production tools and assembly lines, ensuring total control of the production process.

 

Cold forming


Forming, coiling, cutting, punching, laminating, welding and assembly of a broad spectrum of parts made of tubes, wires, cables and sheet metal.

Cutting - Stamping


Production of functional parts including pressfit connectors by bending, punching and cutting metal and non-ferrous strips, including overmolding and assembly.

Metal spinning


Production of axially symmetrical parts without welding by centrifugal forming of steel, stainless steel, aluminum, titanium and alloys.

Overmolding


Production of connectors and housings by overmolding of die-cut contact parts using vertical and horizontal injection molding machines.

3D printing


Additive manufacturing of parts for aeronautical and industrial applications, with a wide choice of plastic materials.

Electro-erosion


Machining of tools, prototypes and small series by wire electro-erosion (EDM), by sink erosion and by fast hole drilling EDM.

Tooling


Making of precision stamping progressive die tools by our in-house teams, experts in materials science and process engineering.
