How to solve the problem of product deformation during die cutting processing?

During the processing of die cut products, deformation occurs. Once the product deforms, it cannot meet the customer's requirements for product quality. This is also one of the problems that many technicians encounter, so what is the reason for the deformation of die-cut products in general?
Firstly, it is important to consider what kind of product is being stamped. Thicker materials may have indentations on the edges, which can lead to deformation; The use of knife molds can also have an impact, as excessive stamping and poor knife interface can lead to material deformation.

Die cutting processing
Summarize the following analysis points:
Mold: It is used frequently, generates too much pressure, and the knife interface is not good, which can cause material deformation.
Knife mold pad: Knife mold pads have height, thickness, hardness, and elasticity, which can also cause product deformation, thickness, and height during production; Punching for too long will cause the knife mold to swell; During the cutting process, if the cushion is too soft or too low, the material will shrink into the cutting die, causing deformation of the product. So choose a suitable knife mold pad.
Tension: For some materials, such as protective films, if the tension is too high, the pressed product may shrink, and the final die-cut product may also deform.
Material thickness: For thicker materials such as PVC and EVA, there may be indentations on the edges during punching, which can also cause deformation of the die cut product.
Small edge products or some irregular products: During the punching process, it can also cause product deformation. For products that are difficult to achieve in one molding, two or more sets of punching can be designed to meet product requirements. Small holes or small margins cannot be directly filled with ordinary cotton pads. Glass glue or silicone can be used to cut them into the desired shape and size, and manually inserted into the mold. If the laser blade mold cannot achieve the desired effect, it is necessary to consider using precision molds (such as corrosion molds, carving molds, etc.). For some difficult products that are difficult to achieve in one molding, two or more sets of punching molds can be designed to meet the product requirements.
