Shenhua Printing Material Knife Plate Spring Pad: A Dual-Optimized Solution for Reducing Noise, Improving Durability and Achieving High-Speed Continuous Die Cutting

In the scenario of high-speed continuous die-cutting (line speed above 350 meters/minute), not only is it necessary to control the die-cutting noise, but also to ensure the wear resistance and long-term stability of the cushion pads. Conventional noise-reducing cushion pads have insufficient wear resistance, while noise-reducing cushion pads have excessive noise. It is difficult to meet the dual requirements of "noise reduction + wear resistance", resulting in enterprises facing the double burdens of environmental noise pressure and frequent replacement of consumables. Shenhua Printing Materials integrates noise reduction and wear resistance technologies to create dedicated dual-優 cushion pads for high-speed continuous die-cutting， balancing environmental protection and production efficiency.

In terms of material optimization， a damping noise reduction + high wear-resistant composite modified material is adopted. The inner layer adds damping noise reduction components， which can absorb the impact energy of die-cutting， reducing noise by 18-28 decibels， controlling the workshop noise below 80 decibels， which complies with environmental noise standards； the outer layer adds silicon carbide wear-resistant particles and anti-fatigue components， with the surface hardness increased to Shore A 65-70， the wear resistance is improved by 60% compared to conventional noise-reducing cushion pads， the anti-compression fatigue times exceed 950，000 times， and the long-term elastic attenuation rate is controlled within 3% or less， avoiding frequent replacement of cushion pads.

In terms of structural design， the surface of the cushion pad adopts a "noise reduction groove + wear-resistant pattern" dual design. The grooves disperse the impact stress， reducing impact noise， and the wear-resistant pattern reduces friction loss， while guiding waste materials to be quickly discharged； the edges are treated with thickened wear-resistant sealing processing to avoid edge damage and shedding caused by frequent friction； the all-area equal-density molding process is adopted， with thickness error controlled within ±0.02mm， ensuring uniform pressure transmission during high-speed die-cutting and avoiding accuracy deviations. After applying this solution in a large label printing factory， the die-cutting noise decreased from 102 decibels to 76 decibels， the replacement cycle of the cushion pad was extended from 5 days to 28 days， the defective rate of high-speed die-cutting decreased from 4.5% to 0.3%， achieving the dual goals of environmental protection and efficiency improvement.
