Wire Harness & Cable Assembly
End-to-end wire harness and cable assembly manufacturing from prototype to mass production — IATF 16949 and IPC/WHMA-A-620 Class 2/3 workmanship, Molex / JST / TE / Deutsch connector sourcing, IP65/IP67/IP68 waterproof options and 100% electrical test.
Application Context
End-to-end manufacturing solutions from prototype to mass production. For pilot and service batches, our low-volume wire harness manufacturing workflow keeps BOM review, material sourcing and test records controlled before full release. built for OEM programs across automotive, medical, industrial and robotics.
Broad wire harness and cable assembly RFQs usually need the same core answers: prototype and low-volume builds, IATF 16949 and IPC-620 quality evidence, Molex / M12 / Deutsch connector sourcing, waterproof options, MOQ, sample timing and production capacity. This page lays out each of these so your sourcing team can scope a quote quickly.
Applications
From automotive and EV to medical, industrial automation and robotics — sealed, tested, custom assemblies for demanding OEM programs.
Sealed engine, body, chassis and EV high-voltage harnesses built for heat, vibration and fluid exposure with automotive-grade wire and connectors.
Control-panel, machine and sensor cable assemblies with shielding and rugged connectors for factory-automation equipment.
Medical-grade cable assemblies with full material traceability and clean workmanship for diagnostic and equipment programs.
High-flex cable assemblies engineered to survive millions of bend cycles on robot arms and moving axes, with reinforced strain relief.
Engineering Challenges
Approved-brand review across Molex, JST, TE, Amphenol, Hirose, Phoenix and Wago, with cost and lead-time alternatives evaluated before release.
Gauge (18–32 AWG), insulation (PVC, Teflon, silicone, TPE, TPU) and temperature class (-40°C to +125°C) matched to the operating application.
Waterproof class (IP65 / IP67 / IP68), overmolding, shielding and strain relief planned for the environment the harness will live in.
Continuity, hi-pot, insulation-resistance and pull-force testing with FAI / COC records planned to the right quality level for the program.

* Client names confidential due to NDA. References available upon request.
EV Automotive OEM · North America
Challenge: The customer needed 50 prototype harnesses delivered within 15 days of PO issuance, including procurement of authorized Amphenol connectors on the same deadline.
Solution: Fast-tracked the production schedule, secured authorized Amphenol connector sourcing and coordinated expedited logistics to hold the 15-day window.
Marine OEM · North America
Challenge: The buyer ran 6 separate RFQs and a 64-email technical deep-dive over two months, and questioned whether an overseas supplier could match the incumbents’ weekly deliveries.
Solution: Held 1–2 day response times through the whole qualification, proposed advance ordering with buffer stock to support the weekly cadence, and documented the test plan.
Industrial Equipment Integrator · Africa
Challenge: The customer required a mid-production design change (V2.0 to V2.1) on a running harness while mandating UL-certified build and custom label and end-treatment specifications.
Solution: Transitioned the line to the V2.1 specification without lead-time penalty, holding the UL requirement and the customer’s labeling spec through the change.
