Shenhua Printing Plate Knife Pad: Upgrade in Surface Treatment Technology and Optimization for Scenario Adaptation

The surface characteristics of the knife plate spring pad directly affect core issues such as material adhesion, paper accumulation, and bonding stability during die-cutting. The requirements for surface performance vary significantly in different die-cutting scenarios. Deephua Printing Materials has introduced multiple types of surface treatment solutions through laminated surface processing technology, precisely adapting to different die-cutting materials and conditions, thereby further enhancing the smoothness of die-cutting operations.

For die-cutting scenarios involving adhesive labels and films that are prone to adhesion, Deephua Printing Materials adopts a special fluorocarbon coating surface treatment process. This coating has extremely low surface tension, effectively reducing the adhesion between the spring pad and the adhesive materials, fundamentally solving the problem of material adhesion to the spring pad after die-cutting. At the same time, the coating has excellent wear resistance and will not fall off due to frequent friction, suitable for high-speed die-cutting operations. After being applied by a certain adhesive label enterprise, the material adhesion rate decreased from 12% to below 0.5%, and the downtime for cleaning was reduced by 60%.

For materials such as corrugated paper and thick cardstock that are prone to paper debris, Deephua Printing Materials adopts an anti-static dust collection surface treatment technology. By forming an anti-static adsorption layer on the surface of the spring pad, it can not only adsorb the tiny paper debris generated during die-cutting, preventing the paper debris from entering the gap of the knife plate and affecting die-cutting accuracy, but also prevent the paper debris from flying due to static electricity and polluting the production environment. At the same time, it does not affect the rebound performance and adhesion of the spring pad, suitable for clean production requirements.

For high-precision die-cutting scenarios that require stable bonding, Deephua Printing Materials has optimized the anti-slip texture surface treatment process. Using laser engraving technology to create fine and uniform anti-slip patterns on the surface of the spring pad, with the pattern depth controlled at 0.1-0.2mm, it can not only enhance the bonding friction between the spring pad and the knife plate, preventing the spring pad from shifting during die-cutting, but also avoid paper accumulation due to excessive pattern depth, combined with high-viscosity back adhesive, providing dual guarantees for bonding stability, suitable for fine-pattern die-cutting.
