Cable Loom Assembly
Custom cable looms built with controlled routing, protection sleeves, clips, labels, strain relief, connectorized ends, and production-ready test documentation.
- Cable loom assembly turns loose wires into routed, protected, installation-ready harness sets.
- OurPCB controls branch geometry, clips, sleeves, labels, strain relief, and electrical testing.
- Best-fit RFQs include drawings, pinouts, clip locations, installation constraints, and annual volume.
- Prototype and pilot builds can start without a forced MOQ before repeat production release.
Build the Loom Around the Installation Path
Cable loom assembly is a manufacturing service that turns a wire list, pinout, and routing requirement into an installation-ready harness. The work is not only cutting and crimping. It includes branch geometry, protection material, connector orientation, clip position, label placement, and packout control.
A wiring loom is a protected wire bundle that keeps conductors routed, identified, and mechanically supported inside equipment or vehicles. A loom drawing should show where the harness bends, where it mounts, where abrasion risk exists, and where service teams need access.
OurPCB combines wire cutting and stripping, crimping, connector assembly, heat shrink processing, and electrical testinginto one controlled release route for prototype, pilot, and repeat production.
Standards references often include IPC workmanship expectations, ISO 9000 quality management principles, and IATF 16949 controls when the loom is for automotive production.
Cable Loom Manufacturing Controls
A reliable loom supplier controls the physical route as carefully as the electrical pinout.
Route-Controlled Loom Builds
Harness branches are built against form boards, routing notes, and customer drawings so clip points, breakouts, and service loops stay repeatable.
Sleeving and Protection Choices
Corrugated tube, braided sleeve, textile wrap, heat shrink, spiral wrap, and abrasion guards are selected around bend radius, noise, heat, and service access.
Connectorized Ends
Terminals, housings, seals, TPA locks, CPA locks, backshells, and branch labels are assembled with revision-controlled work instructions.
Clip and Retention Control
Mounting clips, tie points, edge guards, and grommet positions are checked before shipment so installation teams do not have to force the loom into place.
Electrical Test Planning
Continuity, pinout, hipot, insulation resistance, and optional pull-force checks are matched to the drawing and risk level.
Production Release Package
Approved looms move into repeat supply with BOM control, visual standards, labels, packout rules, and change review for alternate materials.

Fixture Control Prevents Installation Rework
On our loom benches, the operator is not judging branch length by eye. Route boards, printed work instructions, clip maps, and sample photos define where the branch exits, where the sleeve stops, and how the connector should face at packout. This matters most when a loom has many mounting points and little slack inside the final equipment.
- 30 AWG to 4/0 AWG wire processing range listed across OurPCB capabilities
- 100% continuity and pinout test options before shipment
- 48-hour prototype path available for simpler loom builds
- No forced MOQ for prototype and pilot cable loom programs
- China and Philippines routing options for cost and tariff planning
Protection Method Tradeoffs
The right loom protection depends on routing space, flex, abrasion, sound, heat, service access, and production volume.
Release Process
The release path keeps prototype lessons from disappearing during the next production lot.
RFQ Route Review
We review the drawing, pinout, clip map, branch lengths, bend radius, protection method, and installation constraints before quoting the loom.
Material and Connector Plan
Wire, terminals, housings, seals, conduit, braid, tape, heat shrink, labels, clips, and alternates are checked against the required environment.
Fixture or Board Setup
Form boards, nail boards, printed route sheets, or reference fixtures define branch geometry and operator inspection points.
Prototype or First Article Build
A controlled first build verifies length, clip fit, branch exits, label positions, connector orientation, and installation-ready packout.
Electrical and Visual Checks
Continuity, pinout, optional hipot, terminal seating, sleeve coverage, clip position, label accuracy, and packout condition are checked before shipment.
Repeat Production Release
Approved builds move into scheduled production with work instructions, revision control, inspection records, and change review for material substitutions.
Documentation for Buyers Who Need Repeatable Looms
OurPCB has served OEM cable and harness buyers since 2005 with China and Philippines manufacturing routes. Cable loom programs can be released with inspection records, test reports, material traceability, first article notes, and change control for approved alternates.
A cable loom supplier is a contract manufacturer that controls the routing, protection, and connectorized build of the loom. For regulated programs, we align the production file with ISO 9001, IPC/WHMA-A-620, IATF 16949, or ISO 13485expectations as required by the application.
A good RFQ should also separate material lead time from assembly lead time. Long-lead connectors, custom clips, specified conduit, and imported labels can control the schedule more than loom labor. Early DFM review helps identify alternates before a line-down shortage appears.
RFQ Inputs
Send route drawings, wire lists, connector numbers, sleeve callouts, clip maps, labels, test limits, and installation photos when available.
Engineering Tradeoff
Use conduit for abrasion, braid for flexible appearance, tape for compact routing, and heat shrink for controlled breakouts and labels.
Production Control
Lock the released build with fixture references, work instructions, inspection checkpoints, electrical tests, and packout rules.
Cable Loom Assembly FAQ
A cable loom is a routed group of wires or cables protected with sleeves, conduit, tape, clips, labels, and terminations so it can be installed as one controlled assembly.
Cable loom assembly is the manufacturing process that cuts wires, terminates contacts, loads connectors, routes branches, applies protection, installs clips or labels, and verifies the finished loom against the drawing.
A wire harness is the broader electrical assembly. A cable loom often emphasizes the routed and protected bundle used for installation. In buyer RFQs, the terms overlap, so we quote from the drawing, BOM, route, and test requirement rather than the wording alone.
Yes. We build automotive cable looms for OEM and Tier supplier programs with IATF 16949 support, PPAP documentation when required, connector sourcing, clip control, branch routing, and 100% electrical test options.
Send the drawing, wire list, BOM, connector part numbers, pinout, branch lengths, clip or grommet locations, protection method, label rules, test limits, quantity, and target ship date. Photos of the installation path are useful when the route is tight.
Yes. Prototype and pilot cable loom builds can start without a forced MOQ. We use pilot feedback to confirm routing, clips, sleeve coverage, labels, and packout before repeat production.
