Waterproof Wire Harness
Waterproof Wire Harness Manufacturing
Dongguan Songyuan Technology Co., Ltd. manufactures and sells electronic wires, new energy storage wires, shielded power cables, ribbon cables, color ribbon cables, and wire harnesses — including waterproof wire harnesses built for moisture-exposed and harsh-environment applications. Since 2017, we have operated our own 2,000 sqm factory in Houjie Town, Dongguan City, with a 60-person team and a reported average annual sales growth of 20%.
Built for Moisture and Harsh Environments
A waterproof wire harness protects electrical connections where moisture, spray, or water exposure would otherwise compromise performance. Our waterproof assemblies serve application areas within our stated scope, including:
- New energy and energy storage systems — sealed wiring for battery and power management environments
- Industrial control and industrial equipment — ruggedized harnesses for factory and server installations
- Automotive and new energy vehicle wiring — protected circuits for vehicle platforms
- Medical wire harnesses — sealed connections for medical equipment
Whether your project calls for overmolded seals, sealed connectors, or jacketed cable constructions, our engineering team reviews your requirements before production begins. Talk to an Engineer about your specification.
Factory Capabilities and Quality Control
Our facility is organized into four operational areas: a wire harness production workshop, a wire drawing and extrusion workshop, a quality inspection area, and a warehouse and shipping area. This in-house structure supports consistent control from raw cable through finished assembly. Certificates available upon request.
Prototyping and Order Quantities
- Prototyping: 48 hours for standard specifications
- Order quantities: Flexible order quantities — prototype runs from 100 pcs, volume production from 1,000 pcs
- Mass production: Mass production typically ships in 15–25 days
