Specialists serving critical, high-reliability sectors including Defence, Medical, and Aerospace. Our processes follow strict TYCO System 25 standards.
ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018, all UKAS accredited and certified by ISOQAR. We run the three as a single integrated management system, audited twice a year at our Southampton site.
We utilise Lean Manufacturing and DFM (Design for Manufacture) principles, ensuring competitive costing and rapid turnaround times for every custom cable assembly.

Every assembly we build is made, inspected and tested at one site in Southampton. Batch sizes run from a single prototype to over 100,000 units, scheduled through our Priority ERP system and built on automated Komax cut, strip, crimp and test machinery. Nothing is subcontracted offshore. One site means one quality system, one set of records, and a factory you can visit before you place the order.

Quality has been the focus here for over 40 years. Every unit we build is electrically tested before dispatch, not a sample from the batch, whether it is a two-wire assembly or a thousand-circuit loom, with hi-pot testing to 1500V where the application calls for it. That is what lets customers book our work straight into production rather than through incoming inspection.
