Product System

Copper Division

We independently develop and produce T1 premium copper materials, tinned copper wires, precision stranded conductors and bare copper stranded wires. Our products feature low resistance, high ductility and fatigue resistance. We support complete internal industrial chain integration and can directly supply conductor raw materials to cable manufacturers.

Plastics Division

We independently develop wire plastic compounds with customizable eco-friendly formulas for oil resistance, low temperature resistance, high abrasion resistance and flame retardancy. The materials support internal cable production and are sold externally as insulation & sheath raw materials for cables.

Cable Division

We mass-produce high-flex drag chain cables, industrial robot cables, new energy cables, medical air tube cables, sensor cables, flat trailing cables and industrial bus cables. Customization of all specifications of high-end special cables is available.

Electronics Division

One-stop processing for industrial control wiring harnesses, M-series connector harnesses, circular connector harnesses, new energy connector harnesses, robot cable management packages and prefabricated bus harnesses. We provide complete wiring solutions based on equipment working conditions.

R&D Strength

  • We have formed three specialized R&D teams dedicated to material science, cable structure design and electronic wire harness development. A team of material engineers and electrical engineers work full-time in our laboratories.
  • Our lab is fully equipped with a complete set of R&D and testing instruments, including swing testers, thermal cycling test chambers, flame retardant test cabinets, resistance measuring instruments, drag chain flex testers and salt spray test machines.
  • We keep developing proprietary formulations independently. Based on customers’ actual operating environments, we deliver customized special cable solutions featuring oil resistance, weather resistance, corrosion resistance and superior flexibility.
  • We hold multiple utility model patents covering cable structures and innovative sheath materials. We continuously upgrade our products to meet the increasingly stringent requirements of the new energy and industrial automation sectors.
  • We support joint R&D with customers and rapid prototype manufacturing. Custom cable test samples can be delivered in as fast as 72 hours, effectively shortening customers’ project development cycles.

Quality Control

Raw Material Incoming Inspection

100% inspection for copper materials, plastic compounds and connector accessories. Unqualified raw materials are rejected entirely.

In-Process Patrol Inspection

Regular patrol inspection for all processes including copper wire, plastic compound, cable and wiring harness production, with real-time recording of process parameters.

Full Item Finished Product Testing

Comprehensive performance tests including continuity, insulation, voltage resistance, bending, abrasion, high-low temperature, flame retardancy and salt spray as per cable performance requirements.

Final Delivery Inspection & Traceability

Each batch of products is archived with unique serial numbers, enabling full production chain traceability to prevent defective goods delivery.

The company strictly implements the ISO9001 quality management system. All products comply with international environmental standards including CE, RoHS and REACH. Standardized quality control procedures are established to guarantee long-term stable cable operation from the source.
