Cold forming of wires, tubes and cables

Industrialisation of springs and metal components


Our engineers specialising in the cold forming of tubes, wires and cable support the industrialisation of all your parts, from flat or wire springs to overmolding and the automated assembly of complex mechatronic sub-assemblies. They use our rapid prototyping processes to speed time-to-market. Co-engineering enables you to choose the processing technologies best suited to the type of parts you need and your production volumes. Our wide range of complementary processes guarantees you optimised mass production.

 

Cutting, stamping, overmolding and assembly

Contacts and fittings


We are specialists in cold forming and polymer overmolding. Cold forming is a metal deformation process used to manufacture parts in tube or wire, laminated parts and all types of springs.
Cutting and stamping are core competencies of CGR, mastered in all our plants around the world. Copper-based metal parts and electrical contacts can undergo plastic overmolding to create components such as solderless connectors.
The various components are then sent to our automated assembly lines to form complete sub-assemblies.

Wire springs


Custom manufacture of wire springs (compression springs, torsion springs, tension springs and push-pull springs), production of micro-springs for precision mechanics.

Flat springs


Manufacture of flat springs, coiled springs and clips in steel, stainless steel and copper alloys from cut metal strips. Manufacture of rewinder springs in cassette.

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.

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.
