Custom Automotive Wire Harness & Cable Assembly Solutions
From CAD design and rapid prototyping to turnkey mass production. We deliver high-reliability automotive wiring looms, EV high-voltage cables, and custom overmolded assemblies with 100% electrical continuity testing.
Manufacturing Capabilities
6 Core Manufacturing & Engineering Capabilities
A fully integrated in-house chain — from automatic wire processing and crimp-force-monitored termination to custom tooling, overmolding and 100% electrical validation.
Precision Automated Cutting & Stripping
Komax automated processing lines deliver repeatable cut length, strip length and seal application accuracy for every wire in the harness.
FLRY-B / TXL / AVSS · 0.35mm² ~ 25mm²
Automated Terminal Crimping with CFM
Servo crimp presses with real-time Crimp Force Monitoring on every cycle, validated by periodic cross-section analysis and pull-force testing.
100% Crimp Force Monitoring
Ultrasonic Wire Splicing & Overmolding
Ultrasonically welded splices and custom overmolded junctions deliver the low-resistance, high-current joint reliability required by EV and battery harnesses.
EV & Battery Harness Joints
100% Automated Electrical Testing
Computerized continuity test boards verify every circuit and connector cavity — zero open-circuit and zero short-circuit guarantee before shipment.
Zero Open / Short Circuit
Custom Plastic Tooling & Injection Molds
In-house mold design and injection molding for custom connector housings, grommets and backshells with rapid tooling turnaround.
25-Day Rapid Mold Delivery
Protective Looming & Waterproof Sealing
Full protective finishing options: corrugated conduits, braided fiberglass sleeves and adhesive heat-shrink for abrasion, heat and moisture resistance.
Conduit / Braid / Heat-Shrink
