Cold forming

Sheet metal, tubes, wires and cables

Cold forming is CGR's core business. We form, stamp, cut, roll, crimp, weld and assemble a wide range of parts to our customers' specifications. We use the latest technology to transform tubes, wires, cables and sheet metal made from steel, stainless steel and a wide variety of non-ferrous alloys. Depending on your specific requirements in terms of industrial processes, we apply heat treatments, shot blasting, grinding, cleaning and other surface treatments.


Automated assembly

Cold forming, welding, crimping and overmolding

Our customers rely on our ability to automate production lines and create special production processes. Our industrial expertise covers the manufacturing and robotic assembly of wire springs, flat springs, welded brackets and hooks, crimped seatbelt cables, busbars, pressure tubes, windscreen wiper arms and many other parts. Working closely with our customers, we design and industrialise complex parts and sub-assemblies to facilitate their integration into customer modules.

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.

Wire springs

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

Cable crimping

Crimping of cables and metal ropes, including automotive safety cables, with 100% inspection for zero-defect production.

Tube bending

Cold forming of tubes and wires by press bending, rotary draw bending or roll bending. Assembly and robotic welding of complex parts with in-line optical control.
