Shenhua Printing Plate Knife Pad: Specialized for irregular die-cutting, solving complex process problems
Due to the irregular contours and uneven force distribution, special-shaped die cutting has become a technical challenge in post-print processing. Ordinary die plate spring pads are prone to problems such as loose adhesion, rough die cutting edges, and ineffective rebound. Shenghua Printing Materials focuses on the pain points of special-shaped die cutting scenarios and specially develops die plate spring pads that are compatible with various special-shaped structures. With customized design and precise craftsmanship, they overcome the complex problems of special-shaped die cutting and help enterprises improve the quality and efficiency of special-shaped product production.
In the design of adapting to special-shaped structures, Shenghua Printing Materials adopts a "outline replication + segmented adaptation" dual scheme. For special-shaped die plates such as arcs, waves, and irregular geometric shapes, the technical team precisely replicates the outline of the die plate through digital scanning, and customizes differentiated hardness spring pads for different parts according to the force characteristics of each part, ensuring that the spring pad is tightly adhered to every contour of the die plate and avoiding defects caused by excessive or insufficient force in certain areas. For example, in circular special-shaped die cutting, a high-hardness spring pad is adapted at the center to ensure support force, and a medium-hardness spring pad is adapted at the edge to improve adhesion, achieving a smooth and error-free die cutting edge for the circular contour.
In terms of process adaptation, Shenhua Printing Materials has introduced special CNC cutting technology, combined with meticulous manual polishing, to ensure that the edge of the elastic pad perfectly matches the special-shaped die plate. The cutting error is controlled within ±0.03mm, avoiding misalignment in die cutting due to the deviation of the elastic pad size. At the same time, for the local parts that undergo frequent friction during the special-shaped die cutting process, a surface strengthening treatment process is adopted to increase the wear resistance by more than 30% in this area, extending the overall service life of the elastic pad and avoiding the need for overall replacement due to excessive local wear, thereby reducing the cost of enterprise spare parts.
In addition, Shenhua Printing Materials also provides exclusive technical support for customers of special-shaped die-cutting. The technicians go to the site to assist in adjusting the installation position of the spring pads and the die-cutting pressure parameters, optimizing the die-cutting process, and ensuring that the qualified rate of special-shaped product die-cutting remains above 99.5%. Currently, this specialized matching spring pad has been widely applied in scenarios such as special-shaped gift boxes, special-shaped labels, and irregular packaging, helping many enterprises break through the technical bottlenecks of special-shaped die-cutting and enhance their product market competitiveness.
