Shenhua Printing Plate Knife Pad: An Advanced Coordinated Solution with Die-cutting Base Adhesive and Buffer Pad

During die-cutting operations, the knife plate spring pad, die-cutting base glue, and buffer pad form the core auxiliary consumable combination. Each single consumable has excellent performance but lacks synergy, which still leads to fluctuations in die-cutting accuracy and increased consumable wear. Deephua Printing Materials, based on the mechanical transmission mechanism of the three components, has launched an advanced collaborative solution. By precisely matching materials and parameters, it achieves the maximum integrated efficiency of "spring pad - base glue - buffer pad".

In the collaboration between the spring pad and the die-cutting base glue, the core issue is "adhesion conflict and uneven adhesion". According to the type of base glue (hot melt glue, acrylic glue, rubber-based base glue), the spring pad back adhesive is matched: hot melt glue base glue is suitable for high-temperature-resistant back adhesive spring pads to avoid failure of the spring pad back adhesive at high temperatures; acrylic glue base glue is suitable for low adhesion conflict spring pads to prevent adhesive reaction-induced detachment and residue; rubber-based base glue is suitable for compatible spring pads of the same material to enhance the bonding strength. At the same time, customers are guided to control the thickness of the base glue (0.1-0.2mm) to avoid base glue overflow affecting the spring pad's rebound.

In the collaboration between the spring pad and the buffer pad, a "hardness gradient matching system" is constructed. When the buffer pad is soft (Shore A 30-40), a medium-hard spring pad (Shore A 50-55) is paired to balance the buffer performance and pressure transmission, avoiding pressure dispersion that leads to incomplete die-cutting; when the buffer pad is hard (Shore A 60-70), a low-hardness high-rebound spring pad is paired to buffer the die-cutting impact force and protect the knife plate and equipment. For thick material die-cutting, a "thick spring pad + thin buffer pad" combination is adopted; for thin material high-precision die-cutting, a "thin spring pad + thick buffer pad" combination is used to optimize the pressure transmission path.

After applying this advanced collaborative solution in a certain color box factory, the die-cutting accuracy error decreased from ±0.1mm to ±0.04mm, the loss rate of base glue and buffer pad decreased by 25%, the service life of the spring pad was extended by 30%, and the efficiency upgrade and cost optimization of the entire auxiliary consumable combination were achieved.
