Shenhua Printing Materials Knife Plate Spring Pad: Leading the upgrade of die-cutting accessories with technological innovation
Shenhua Printing Materials has always adhered to technological innovation-driven development, focusing on the performance optimization and environmental protection upgrade of the knife plate and spring pad. It has formed a professional R&D team and has accumulated multiple industry technology patents. With core technologies, it leads the upgrading of the die-cutting accessories industry and emempowerment of post-press processing techniques.
One of the core innovative technologies is the "Dynamic rebound adjustment Technology". The R&D team of Shenhua Printing Materials has developed a elastic pad product that can dynamically adapt the rebound force according to the die-cutting speed and pressure by adjusting the rubber formula and vulcanization parameters. The traditional spring pad has a fixed rebound force and cannot adapt to different die-cutting scenarios. It is prone to problems such as excessive indentation during low-speed die-cutting and lagging rebound during high-speed die-cutting. The Shenhua Printing material knife plate spring pad equipped with this technology can automatically adapt to die-cutting speeds of 300 to 1,200 times per minute, dynamically adjust the rebound force, ensure consistent die-cutting accuracy in different scenarios, and eliminate the need for manual adjustment, significantly enhancing production convenience.
In terms of environmental innovation, Shenhua Printing Materials has developed a "halogen-free, environmentally friendly and wear-resistant formula", eliminating the halogen-containing plasticizers and harmful additives in traditional elastic pads, and creating an environmentally friendly elastic pad that meets the EU REACH certification and the US FDA food contact standards. This formula not only enhances environmental friendliness but also increases wear resistance by 30%, addressing the industry pain point of traditional eco-friendly spring pads being "environmentally friendly but not wear-resistant". It is suitable for high-end environmental protection demand scenarios such as food packaging and infant product packaging, filling the gap of high-end eco-friendly spring pads in the industry.
In terms of production technology innovation, Shenhua Printing Materials has introduced a "digital intelligent manufacturing production line", achieving full digital control over raw material ratios, vulcanization parameters, and cutting accuracy. The production efficiency has increased by 50%, and the product consistency qualification rate has reached over 99.9%. Meanwhile, the R&D team innovatively adopted the "surface nano-coating technology", covering the surface of the elastic pad with an ultra-thin nano-wear-resistant coating. This reduces the friction coefficient by 40%, further extends the service life, and effectively avoids the problems of scratches and adhesion that occur during die-cutting. It is suitable for die-cutting requirements of easily damaged materials such as special paper and laminated paper.
By breaking through industry bottlenecks through technological innovation, Shenhua Printing Materials' knife plate spring pads have not only achieved iterative upgrades in their own performance but also driven the entire die-cutting accessories industry towards high efficiency, environmental friendliness, and precision, demonstrating the technological strength and sense of responsibility of a leading enterprise in the industry.
