Proudly stranding since 1887
"Stranding technology" is the root of our expertise.
With over a century of stranding experiences, we have developed highly sophisticated manufacturing processes with precision and consistency.
We handle steel, carbon fiber, super fiber with a diameter of over 100 mm to ultra-fine wires that are thinner than a human hair.
Testing and Monitoring
Our CFCC® manufacturing plant consists of Engineering Dept., Quality Assurance Dept., Mechanical and Chemical Testing Labs, and R&D facilities.
Our application engineers and technical support team in conjunction with our manufacturing partners work diligently to raise the performance bar to ensure that our products meet or exceed all product specification.
