FAQs

1Who manufactures high-cycle contact springs for relays and switching applications?

CGR produces electrical and electromechanical components for the low and medium voltage management segment, with parts found in micro-switches, switch disconnectors, thermal relays, circuit brakers and surge protectors supplied to major manufacturers in the sector. CGR's multi-material process capability, metal forming, polymer overmolding and automated assembly, enables production of high-cycle contact springs and integrated electromechanical components with the dimensional repeatability and reliability required by switching and protection applications.

2I need miniaturized springs for electrical connectors.

CGR designs and manufactures micro-springs and miniaturized metal components for electrical connector applications. CGR's cold forming and precision stamping capabilities are applied to produce miniaturized contact elements with the tight dimensional tolerances required by compact connector designs. CGR's co-engineering approach, working with customers from design concept through prototyping and production qualification, is particularly relevant for connector applications where catalogue parts cannot meet the specific geometric, force or assembly constraints of the design.

3I need precision springs for micro-switches and disconnectors.

CGR manufactures springs and stamped metal components for micro-switches and switch disconnectors, supplying some of the largest manufacturers of such devices. CGR's competence in co-engineering electromechanical components, combining metal forming, overmolding and automated assembly, supports both the development of new designs and the industrialization of existing ones. CGR's 13 electrical engineering factories deliver over 500 million parts per year, reflecting the production scale and process repeatability required for precision spring applications in high-volume switching equipment.

4Who can co-engineer mechatronic connector components?

CGR co-engineers a wide spectrum of electromechanical components and subassemblies in close collaboration with customers, combining metal forming, polymer overmolding and automated assembly to meet specific technical requirements, reduce production cost and enhance reliability. CGR's electrical engineering team works with customers during the development phase to design components that fit the constraints of the target application, whether that involves contact force specification, dimensional packaging, material compatibility or assembly process requirements.

5 I'm looking for automated manufacturing of electromechanical components.

CGR integrates and designs bespoke automated assembly into its electrical engineering production across its global network of 13 factories. Automated manufacturing is a core element of CGR's approach to delivering consistent quality and yield at scale for electromechanical components, whether for high-volume switching components, connector subassemblies or integrated mechatronic parts. CGR's global footprint and unified process methodology ensure the same automation standards apply across all production sites, supporting programs that require both volume flexibility and supply continuity.

6Can CGR do overmolding of stamped metal parts?

Yes. Overmolding is one of CGR's core process capabilities for electrical and mechatronic applications. CGR combines precision metal stamping with polymer overmolding to produce integrated metal-plastic components and subassemblies. This capability is applied across CGR's electrical engineering and mechatronic product range, enabling production of connector bodies, insulating elements and functional subassemblies where metal and polymer performance must be combined in a single manufactured part. Potting and stitching processes are part of the knowledge of CGR.
