What CGR does

CGR International SAS is a French-headquartered, privately held industrial manufacturer specializing in custom springs, cold-formed metal components, and mechatronic sub-assemblies for the aerospace, automotive, medical, electrical engineering, and broader industrial markets. The company operates two main technology pillars: a springs platform (under the Springtelligence brand) covering compression, tension, torsion, variable pitch, spiral, constant-force, power, flat, and micro-springs with wire diameters approaching 0.05 mm; and a mechatronics platform combining overmolding, plastic injection, cutting-stamping, and automated assembly. These are complemented by cold forming capabilities including cable crimping, tube and wire bending, metal spinning, precision machining (achieving 3 micrometer accuracy), and in-house tooling. Differentiated technologies include the patented ELOPIN PressFit connector system, biomimetic cable crimping, and the STRAIN R&D laboratory operated in collaboration with INSA Toulouse and Institut Clément Ader.

The company runs a sales-led, co-engineering go-to-market model: CGR partners with customers from feasibility study and design through prototyping, tooling, industrialization, and mass production, with pricing on a quote-based, multi-year contract basis and self-service online configurators for tension and compression springs. With approximately 1,500 employees across 24 autonomous production sites in 11 countries on four continents, located near major customer factories, CGR provides local responsiveness with global reach and just-in-time delivery for demanding aerospace and automotive supply chains. Certifications include ISO 9001, IATF 16949, EN/AS 9100, and ISO 14001 (95% of factories, 100% targeted by 2026); CGR also holds a 2025 EcoVadis Bronze Medal (62/100, top 35%) and operates under a sustainability program targeting 50% Scope 1+2 carbon reduction by end-2025 and carbon neutrality by 2030.

Founded in 1963 and led by Director General Alexis Martel, CGR operates as an independent private company under French SAS structure with no disclosed parent, external investor, or M&A activity in the source data, though an Acquisitions page on its corporate site suggests tuck-in M&A is a possible strategic lever. Aerospace and automotive are the two primary revenue verticals, with medical, electrical engineering, and general industrial applications as secondary segments.

Products and services

• Compression Springs Custom-manufactured helical compression springs that resist axial loading, produced from wire diameter typically down to 0.05 mm for precision applications across aerospace, automotive, medical and industrial customers.
• Tension Springs Custom-manufactured helical tension springs that oppose axial elongation, featuring loops or hooks for attachment and available with German or English loop configurations.
• Torsion Springs Custom-manufactured helical torsion springs that store and release angular energy when twisted, available in single, double, and spiral configurations.
• Variable Pitch Springs Helical springs with varying spacing between coils that provide progressive, non-linear force response and help attenuate oscillations in high-frequency applications.
• Spiral Springs Springs wound from strip or flattened round wire that absorb and release torque, providing stable quasi-linear torque in tight tolerances for long-term energy storage.
• Constant-Force Springs Spiral springs with uniform coil diameter that deliver nearly constant force throughout their working range, suitable for push-pull and rotary movements.
• Power Springs Prestressed strip springs that store energy when coiled and release it during unwinding, serving as economical alternatives to motorized drives for energy storage applications.
