In die-cutting processes, the issue of white edges is a common challenge encountered by many manufacturing enterprises in actual operations. It not only affects the appearance of the products but also relates to material utilization and production efficiency. Shenhua Printing Materials has 25 years of experience in the manufacturing of knife plate spring pads. Its SPEED knife plate spring pad, relying on the accumulation of material research and development and production technology, provides a feasible solution to the problem of white edges.
When dealing with the white edge issue, the SPEED ejection rubber focuses on the material presentation and structural design. Shenhua Printing Materials uses its self-developed foaming process to reasonably control the density and hardness of the foam, ensuring that the SPEED knife plate spring pad has a stable rebound performance, with a rebound rate maintained above 45%. In die-cutting operations, good resilience helps provide uniform support when the die is pressed down, facilitating the blade to smoothly cut into the material. When the die is lifted, the spring pad can promptly return to its original position, effectively separating the material from the die, thereby reducing the occurrence of white edges caused by pulling or squeezing. This processing method that starts from the material itself is the fundamental reason why the SPEED knife plate spring pad works.
In addition to material properties, the SPEED knife plate spring pad also combines multiple structural designs to provide more support for controlling white edges. Shenhua Printing Materials has developed products with different structures, such as single-sided wavy knife plate spring pads and granular groove spring pads, based on various die-cutting scenarios. These products are designed to adapt to different knife model states and cutting angles, assisting in improving the force state of the material during cutting and making the cut surface flatter. Whether paired with laser die-cutting dies or etched die-cutting dies, the SPEED die-cutting plate spring pad can maintain stable performance, which helps to improve the overall quality level of die-cutting products.
Shenhua Printing Materials pays close attention to every aspect of the product manufacturing process, from raw material selection to foaming molding and then to slitting processing, all of which are systematically managed to ensure that the SPEED knife plate spring pad remains stable in terms of density design (up to 1000g/㎡) and service life (capable of supporting over 300,000 stamping cycles). Based on the emphasis on product consistency, the SPEED knife plate spring pad has been applied in the production processes of many enterprises such as Yutong Group and Lijia Group. In the die-cutting operations of packaging and electronic film products, it provides support for improving the white edge problem.
