National standards are the bottom line, our standards are the benchmark: Our high-frequency welding rolls win the market with quality exceeding national standards.

In the field of high-frequency welding roll manufacturing, national standards are the industry's entry threshold, not our company's quality ceiling. For many years, we have consistently practiced a set of internal standards that far exceed national standards.

This standard stems from a deep understanding of our customers' high-end needs and long-term technological accumulation, and has been continuously optimized and improved through production practice. Its requirements for precision control, performance stability, and durability are significantly stricter than national standards. This is the core reason why our products can stand out with superior quality and continuously provide outstanding value to our customers' production lines.
