Custom Wire Harnesses

Wire Harnesses

A wire harness, also known as a cable harness, is an organized assembly of electrical wires, cables, terminals, and connectors used to transmit power or signals inside a machine, device, or system. By combining multiple wires into one routed unit, a wire harness simplifies installation, reduces wiring errors, and helps protect conductors from vibration, abrasion, moisture, and mechanical stress.

A typical wire harness includes wires or cables, connectors, terminals, and protective or fastening components such as sheathing, braided sleeving, heat shrink tubing, insulation tape, cable ties, and other accessories.

Process Features

Wire harness manufacturing is highly customized, as most assemblies are built according to the customer’s product structure, wiring layout, installation space, and electrical requirements.

  • Custom design: Harness layout, wire length, branch routing, connector type, and protective materials can be configured for specific equipment, such as automotive systems, industrial equipment, household appliances, medical devices, and other applications.
  • Precision cutting, stripping, and crimping: Wire lengths are controlled according to drawings to avoid assembly issues caused by cables that are too long or too short. Terminal crimping is managed to support reliable conductivity and pull-force performance.
  • Bundling and assembly: Multiple wires are routed and secured with tape, cable ties, sleeves, or other accessories to keep the harness organized and easy to install.
  • Protective finishing: Sleeving, corrugated tubing, heat shrink tubing, insulation tape, and overmolding can be used to improve abrasion resistance, moisture protection, and mechanical durability.
  • Electrical testing: Continuity testing and other inspections can be applied to verify correct wiring and connection performance before shipment.
