Zhejiang Yonghui Corrugated Roller Company, established in 2004, has been dedicated to the design, manufacture, and retrofit of high-performance corrugator rolls and corrugated board machinery. With over two decades of industry experience, we provide reliable solutions that meet the demands of high-speed production, reduce material consumption, and ensure consistent board quality. To strengthen our capabilities, we’ve invested over 80 million RMB in advanced equipment and built a specialized in-house R&D team, along with a comprehensive service network to support our global clients. We are committed to delivering innovative corrugating roll solutions that combine efficient production performance, exceptional wear resistance, and long service life supporting corrugated board manufacturers worldwide with consistent reliability and technical precision.
Yonghui has established its core competitiveness through a number of industry-first advancements. We were among the first in the industry to adopt the JP8000 supersonic thermal spraying system from the U.S., a breakthrough that dramatically elevated the wear resistance of our tungsten carbide coatings. Precision is built into every step of our process, our fully automated CNC grinding machines ensure roundness tolerances within 10μm, aligning with world-class manufacturing standards.
Our independently developed flute profile designs are optimized to fully meet the demands of modern corrugated board production lines, ensuring high-speed operation, efficient output, and enhanced board strength across various applications.
Our manufacturing process integrates multiple proprietary innovations to deliver performance beyond conventional standards. Our combined heat treatment process is developed in-house that seamlessly integrates nitriding, medium frequency quenching, cryogenic treatment, and tempering. This advanced approach significantly enhances the hardness, wear resistance, and structural stability of the roll body, extending product lifespan by over 30% compared to traditional methods.
Another standout achievement is our peripheral heating corrugating roll technology, which has earned high recognition in both domestic and international markets. Rigorously tested and certified by leading global equipment manufacturers such as BHS and Fosber, this technology now holds a 40% market share in China, underscoring our strength in transforming technical innovation into real-world manufacturing value.
