Four manufacturing bases · 4,000+ braiding machines · 87 patents · 200 million meters/year. Turning material capability into protection solutions customers can actually deploy — that has been the mission since 2002.
WCW (WAHCHANGWEI) is among China's larger manufacturers in high-temperature composite materials, delivering protection solutions for high voltage, high temperature, mechanical friction, harness routing and fastening scenarios.
Products are used across smart home appliances, power electronics, clean energy, rail transit, aerospace, automotive harnesses, transformers, power modules and industrial equipment — sold throughout China and exported to Europe, the Americas and Southeast Asia, reaching 60+ countries.
The newest base — commissioned in 2025, located in the Heyuan National High-Tech Development Zone. 50,000 m² modern manufacturing center, 5,000 m² R&D center, total investment $500,000. Designed for scale, automation, and the addition of silicone wire, heat shrinkable tubes, corrugated tubes and self-wrap sleeving lines.
R&D, production and business support coordinated across four sites. The Shenzhen and Ningbo bases pre-date Heyuan — each retains its role.
