Our Custom wire harness manufacturing services

Engineering & technical support

Our engineering team reviews your drawings and specifications before production. We verify cross‑sections, terminal types, lengths and tolerances to ensure each harness meets your requirements.

Digitised planning & real‑time tracking

Every order is managed through our internal digital platform. Operators record each step via tablets, providing complete traceability from order launch to delivery.

Prototyping & small runs

We build functional prototypes to validate connections and dimensions, and we accept small series with no minimum order.

Reliable logistics

We arrange deliveries across Spain and internationally using trusted logistics partners to meet agreed deadlines and deliver your harnesses in perfect condition.

Direct communication

You deal directly with the team that builds your wire harnesses. We respond quickly to technical queries, drawing adjustments or incidents—no intermediaries.

Ready‑to‑integrate sub‑assemblies

We supply complete wire harnesses and sub‑assemblies ready to integrate into your production line: connectors fitted, sleeves applied and labelling included.

Certified materials & compliance

We source UL, CE and RoHS‑certified cables and components from selected suppliers and adapt each material to your technical and regulatory requirements.

Our methodology

Wire harness manufacturing process

1. Requirement & specification review

Send us your drawings or requirements. We analyse cable cross‑sections, terminal types, quantities and lead times, and ask clarifying questions to prepare your quote.

2. Detailed quote within 24 hours

Our technical team prepares a tailored quote covering materials, quantities, lead times and options. You receive a clear, competitive proposal within one business day.

3. Order confirmation & scheduling

Once you approve, we schedule production in our digital system, assign a unique tracking number and allocate the relevant operators.

4. Technical validation

Before production begins, we review all documentation, drawings and standards. If we identify inconsistencies or potential improvements, we contact you before proceeding.

5. Precision cutting & stripping

Our automated Komax and Schleuniger machines cut cables to exact lengths, ensuring millimetre precision and consistent stripping.

6. Crimping & terminal assembly

We maintain over 200 terminal references and operate various presses and applicators to crimp terminals exactly as specified.

7. Lead‑free soldering & tinning

We perform solder‑pot or iron soldering according to project requirements, with lead‑free options for RoHS compliance.

8. Connector & housing assembly

Our teams assemble connectors, housings, protective sleeves and mechanical components exactly as drawn—no unvalidated changes.

9. Sorting & labelling

Once assembled, harnesses are sorted by project, reference and client, labelled and prepared for final verification.

10. Double quality check

Every harness undergoes visual inspection and electrical testing for continuity, polarity and tolerance compliance before it leaves our workshop.

11. Shipping & delivery

We prepare each shipment with appropriate packaging, labelling, technical documentation and delivery tracking, and ship across Spain and internationally through our own resources or trusted partners.
