Our wiring harness manufacturing process

Our wiring harness manufacturing process

1. Design and Prototyping

Custom designs are created to customer specifications, followed by prototyping to validate performance and ensure a proper fit.

2. Wire Processing and Pre-Assembly

Raw wires are cut and stripped, then prepared for assembly through threading silicone tubing and inserting connectors.

3. Crimping and Riveting

Terminals are crimped to wires using mechanical devices, and in some instances, rivets are used to ensure a secure connection.

4. Assembly and Final Assembly

Wires are assembled into their final form according to the drawings, including board layout, wiring, and packaging, and installing sizable corrugated tubing on the main line.

5. Quality Control and Electrical Testing

Finished products are inspected for dimensions and aesthetics to ensure compliance with specified standards. Subsequently, circuit continuity is verified using electronic testing instruments.
