Our Cable Assembly Capabilities

Flexible Materials and Component Options: We work with a broad range of conductors including bare copper, copper alloys, tinned and silver-plated wire. Insulation materials include PVC, PE, PP, Teflon and silicone rubber. We source high-quality heat-shrink from suppliers such as 3M, TE and Alpha Wire, and support an extensive range of connectors including Amphenol, TE, Molex, JST, Hirose, LEMO and Deutsch, as well as customer-specified alternatives.
Overmoulding and Encapsulation: We provide custom injection-moulded overmoulds for improved durability, strain relief and environmental sealing. Potting services are also available to protect internal components from moisture, vibration and chemical exposure where required.
Prototyping and Low-Volume Support: Our rapid prototyping service allows customers to validate designs before committing to full-scale production. We also support low-volume and mid-volume builds for design verification, pre-production trials and ongoing small-batch requirements.
High-Volume Production Scalability: Through our controlled supply chain and certified partner network, we can support high-volume production with no strict upper limit. Operations are scaled to align with scheduling requirements while maintaining consistent quality and reliable delivery.
Testing and Quality Assurance: Quality control is embedded into every stage of manufacture. Every cable assembly undergoes 100% electrical testing including continuity, Hi-Pot and functional testing. Dimensional inspections verify connector pinouts, wire lengths and assembly layout. Pull-testing confirms mechanical integrity, and visual inspections ensure workmanship meets required standards.
Standards and Compliance: Cable assemblies are produced to IPC/WHMA-A-620 workmanship standards. Our facility and partner network operate under ISO9001, ISO14001, ISO45001, ISO13485 and IATF16949 certified management systems.

Our Production Process

Design Review: Our engineering team reviews schematics, specifications and application requirements. We provide design-for-manufacturability guidance to optimise functionality, cost and long-term reliability.
Prototype Development: Approved designs progress quickly to functional prototypes, enabling customer testing, validation and refinement.
Manufacturing: Production is completed through certified processes and a controlled supply chain. Work instructions and in-process inspections ensure repeatability and consistency across all volumes.
Testing and Quality: Assurance Every cable assembly undergoes electrical, mechanical and visual inspections. Full documentation, testing records and certificates of compliance are supplied as required.
Packaging and Delivery: Assemblies are packaged to protect against static, moisture and transit damage. We can also pack completed assemblies in a manner which increases efficiency at the receiving end, especially if used in a production environment. We coordinate all logistics to ensure reliable, on-time delivery.
