Products & Services

From a single prototype to full series production

Consultation, engineering design and manufacturing under one roof — with the flexibility to scale as your programme grows.

High Mix, Low Volume

Start small. Scale when you are ready.

Many manufacturers will not quote low volumes, and many that will cannot scale afterwards. Our High Mix, Low Volume capability is built for customers testing a market or validating a design — without locking you out of mass production later.

  • Many product variants in small quantities
  • Ideal for prototyping and market testing
  • Same quality system as our mass production lines
  • A clear path to scale with the same supplier
Wiring Harness Products

Wiring harnesses and cable assemblies

Custom wiring harnesses engineered to your specification and application — for combustion and electric vehicle platforms, machinery, appliances and specialist equipment.

Engineering Services

End-to-end engineering support

Our engineers are involved from the first conversation — so problems get solved on the drawing, not on the production line.

01

Consultation

We review your requirement, application and volumes before anything is quoted.

02

Engineering Design

Specialist engineers develop and refine the harness design with you.

03

Prototyping

Low-volume builds to validate fit, function and manufacturability.

04

Validation

Testing and quality checks against IATF 16949 disciplines.

05

Delivery

Series production and delivery, with traceability throughout.

Engineering Services

Support at every stage

You can bring us a finished drawing, or a problem and a rough idea. We work from either.

Consultation & Feasibility

We review the application, volumes and target cost before quoting.

Harness Design & Routing

Design support and routing optimisation with our engineering team.

Prototyping

Low-volume builds to prove fit, function and manufacturability.

Jigs & Tooling

In-house build boards and fixtures matched to your harness.

Testing & Validation

Electrical and mechanical verification before release.

Production & Delivery

Series production with traceability and scheduled delivery.

Quality Assurance & ESG

Quality you can audit

Our processes are certified to IATF 16949 and ISO 9001, with end-to-end traceability from incoming material to delivered assembly. Procurement and quality teams get the documentation they need to sign us off.

  • IATF 16949 and ISO 9001 certified processes
  • End-to-end traceability across the production flow
  • Transparent, auditable quality reporting
  • Japanese OEM production disciplines

Continuity Testing

Every harness checked for circuit continuity before it leaves the line.

Crimp Verification

Crimp height and pull-off checks to catch termination defects early.

Full Traceability

Material and process records traceable from incoming goods to shipment.

Documentation

Quality documentation prepared for your approval and audit process.
