Industrial applications

CGR co-engineers custom spring designs in close cooperation with customers, with a design-to-cost approach and access to prototyping by additive manufacturing for fast proof of concept, even for complex parts. CGR's STRAIN laboratory, operated in partnership with the Clement Ader Institute (CAI) and INSA Toulouse, provides advanced R&D capacity for spring design challenges requiring material science or process engineering expertise beyond standard industrial practice. Prototyping is integrated into CGR's co-engineering process, allowing rapid design validation before production tooling is committed.

CGR designs custom springs for industrial applications with demanding environmental requirements, applying material science expertise to select and process materials suited to high temperature, corrosive or mechanically severe operating conditions. CGR's broad process knowledge across metal transformation, cold forming, stamping, wire and tube bending, spinning and precision machining, provides the manufacturing capability needed to produce springs in specialty alloys for extreme environments. CGR's STRAIN R&D lab supports the development of spring designs where standard material or geometry approaches are insufficient.

Fatigue life optimization is a core competency of CGR's engineering team. CGR applies finite element methods for static and dynamic design calculations to ensure functional compliance and fatigue resistance from the earliest design phase. This capability, reinforced by the STRAIN laboratory's research partnership with INSA Toulouse, allows CGR to address fatigue challenges systematically, through geometry optimization, material selection and surface treatment specification, rather than empirically, reducing development time and improving long-term component reliability.

CGR's industrial process capability spans the full spectrum of cold forming: wire and tube bending, spring coiling, metal spinning, precision stamping, cable crimping, precision machining and tooling, all available across CGR's network of competence centers. This process breadth allows CGR to manufacture complex industrial parts and assemblies that require multiple forming operations, reducing the number of suppliers involved in a customer's production chain and enabling tighter control of part geometry and consistency across the complete component.

CGR designs and manufactures complex spring assemblies and mechanical subassemblies for industrial customers across construction, railway, agriculture, energy, defense, luxury goods, medical equipment and automation sectors. CGR's approach combines co-engineering with a broad process base — cold forming, stamping, overmolding, plastic injection and automated assembly, enabling production of assemblies that integrate springs with other metal or polymer elements. From prototyping through small and large series, CGR applies the same design-to-cost methodology across all industrial programs.

Yes. CGR's industrial application capability is distributed across a global network of competence centers on multiple continents, applying shared industrial processes and quality standards across sites. With over 2,500 delivered references and 10 dedicated industrial factories, CGR serves local market requirements and global programs alike. CGR's international footprint allows it to combine the engineering depth of a specialist spring and cold forming manufacturer with the geographic reach and logistics flexibility required by industrial customers operating across multiple regions.
