CGR co-engineers and manufactures mechanical and mechatronic components as well as sub-assemblies for automotive, aerospace and other industries. With production units on 4 continents, we support clients locally while offering a global footprint. Our international teams share a broad spectrum of skills and technologies, centered on cold transformation and overmolding of metal. Clients the world over count on our expertise for co-engineering and serial production of a wide variety of parts.

Aerospace, automotive and beyond

Serving the world’s most demanding industries

Producing springs and sub-assemblies for over 50 years, our parts and products today can be found across major commercial airplane and automotive brands. We also design and make components for electrical engineering and many other industries. CGR’s capacity to continuously fulfil the high-volume requirements of car production and stringent quality standards of aerospace provides a sound base for any manufacturing project, whatever the market to be served. Just ask us how.


Cold forming, metal transformation and overmolding

An inclusive approach to manufacturing

Drawing from a deep pool of competencies, skills and expertise, our mechanical engineers and manufacturing operators enable us to solve even your most complex manufacturing issues. In local, autonomous, and agile production units, our people share knowledge and methods in process engineering, material science and quality control across our international organization. We produce our own tools and assembly lines, for control over the entire process, driving costs down, and quality up.


Cold forming

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

Metal 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.


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

Automated assembly

Complete automation of production and assembly lines for complex parts (plastic, contacts, springs, etc.) using our own robotic technology.

3D printing

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


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


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