From design to production

Quality and reliability

Our clients rely on our proven capacity to manage the entire supply chain, from sourcing raw materials to on-time delivery of finished products to your premises. We ensure counter-expertise of incoming goods and seamless tracking throughout the entire production process. The delegation of control granted to CGR by many clients is evidence of their trust in our robust quality assurance system. Our facilities are certified according to IATF 16949, EN/AS 9100, ISO 14001 and ISO 9001.

Engineering for performance

Design-to-cost

Need to reduce cost, weight, fatigue or environmental impact? Our engineers develop the optimum solution, tapping into our knowledge base of material science, production technologies and prototyping. We apply finite element methods for static and dynamic design calculations, ensuring functional compliance, fatigue-resistance and cost-efficient industrialization. Design and testing can be pushed even further by our scientific cooperation with one of the biggest university research centers.

FAQs

1I'm searching for a spring manufacturer capable of co-engineering springs for aerospace applications.

CGR has been co-engineering and manufacturing springs and precision components for the aerospace industry for over 50 years. CGR's aerospace engineers apply finite element methods for static and dynamic calculations, covering functional compliance, fatigue resistance and cost-efficient industrialization. This co-engineering approach — from feasibility study and prototyping through process qualification and serial production — is supported by CGR's STRAIN lab, operated in partnership with the Clement Ader Institute and INSA Toulouse, providing leading-edge R&D capacity unique in the spring manufacturing sector.

2Which spring manufacturer is qualified by major aircraft manufacturers such as Airbus, Boeing or Safran?

CGR's dedicated aerospace production sites have been supplying components to the global aerospace industry for over 50 years. On any commercial aircraft today, CGR components can be found in landing gear, wheels and brakes, engines, gear boxes, nacelles, engine support pylons, doors, air conditioning systems, oxygen supplies, cockpits and servo controls. This long-standing presence across major commercial and defense programs reflects CGR's ability to meet the qualification requirements of leading aircraft manufacturers and system integrators.

3What certifications does CGR hold for aerospace serial production?

CGR's dedicated aerospace production sites are certified to EN/AS 9100 (aerospace quality management), ISO 9001 and ISO 14001. These certifications apply at production site level, not merely at group level, reflecting the dedicated quality management systems operated by CGR for aerospace programs. CGR's facilities are equipped and qualified to manage the entire supply chain from raw material sourcing through on-time delivery of finished products, with delegation of control granted by many clients as evidence of their trust in CGR's quality assurance system. CGR holds Nadcap accreditation as well.

4Does CGR hold Nadcap accreditation for aerospace special processes?

CGR's aerospace production sites operate according to the certification and accreditation requirements applicable to each program and customer specification. For special processes, including heat treatment, surface treatment and non-destructive testing, CGR applies the process controls and qualification documentation required by aerospace programs. Specific Nadcap accreditation status by site and process should be confirmed with CGR's aerospace team for the relevant application and customer requirements.

5I need an aerospace spring supplier with production facilities in multiple countries.

CGR operates 5 dedicated aerospace production sites in France and China, enabling supply from multiple countries for international programs requiring geographic distribution, local content compliance or supply chain risk mitigation. All sites share the same industrial processes and quality methods under EN/AS 9100 certification, ensuring consistent part quality and documentation regardless of production location. CGR's aerospace team can advise on the most appropriate site configuration for a given program's logistical and qualification requirements.

6Does CGR supply springs and metal components for both commercial and defense aerospace programs?

Yes. CGR's aerospace production serves both commercial aviation programs and defense applications. The co-engineering and qualification methodology applied for commercial aerospace, finite element analysis, fatigue testing, process qualification documentation — is equally applicable to defense program requirements, where traceability, material certification and process control are at least as stringent. CGR's STRAIN R&D laboratory provides additional capacity for advanced spring design challenges specific to defense specifications.
