Shenhua Printing Plate Knife Pad: The Ultimate Precision and Damage Prevention Solution for Ultra-Thin Die-cutting Scenarios

With the development of the electronics and micro-packaging industries, scenarios of ultra-thin die-cutting (such as electronic protective films with a thickness of less than 0.03mm, micro-labels, and precision instrument packaging) are increasing. These scenarios have extremely high requirements for the precision, flexibility, and anti-breakage ability of the die-cutting tooling pads - conventional pads are difficult to fit, and those with excessive elasticity are prone to causing material stretching, while those with insufficient elasticity fail to achieve thorough die-cutting. This has become the core bottleneck of ultra-thin die-cutting. Deephua Ink Materials focuses on this niche field and has developed ultra-thin die-cutting-specific die-cutting tooling pad materials, achieving a breakthrough in both extreme precision and anti-damage capabilities.

In terms of material and thickness optimization, Deephua Ink Materials innovatively adopts nano-level ultra-thin elastic materials, breaking through the thickness limit of traditional rubber materials. The minimum thickness of the pad can be customized to 0.2mm, and through molecular chain densification treatment, it can still maintain a high rebound rate of 97% or more at ultra-thin thickness, with a compression permanent deformation rate of ≤3%, avoiding elastic attenuation due to excessive thickness. At the same time, the flexibility of the material is optimized, with the elongation at break increased to over 500%, which can adapt to the die-cutting pressure of extremely thin materials, avoiding material stretching and damage. In terms of precision control, a seven-axis precision cutting equipment is used, with the pad thickness error controlled within ±0.01mm, and the edge cutting has no burrs or warping, ensuring precise adhesion with the ultra-thin die-cutting tooling, and eliminating the problems of missed cutting and multiple cuts.

To address the problems of anti-sticking and waste disposal in ultra-thin die-cutting, the surface of the pad is coated with a special nano anti-sticking coating, with the friction coefficient reduced to below 0.08, effectively preventing the extremely thin materials from sticking to the pad, and optimizing the surface micro-ridges to facilitate the rapid removal of small waste. After applying this solution to a micro electronic label enterprise, the defective rate of ultra-thin label die-cutting decreased from 9% to 0.2%, the material loss rate dropped by 85%, the die-cutting speed increased by 25%, fully meeting the strict requirements of precise ultra-thin die-cutting. In addition, Deephua Ink Materials also provides exclusive adhesive guidance for ultra-thin pad materials, using a dedicated ultra-thin adhesive to ensure a secure and residue-free removal, further guaranteeing the die-cutting precision.
