What do you think caused the deformation of die-cutting products?

What should die-cutting products do if they are deformed during processing? This is one of the problems that many technicians will encounter. At this time, the first thing technicians need to do is not to find out whose fault it is, but to find out the problem in time and then find out the corresponding solution. So let's discuss with Suzhou Kedou Precision today. What causes the deformation of die-cutting products?

First of all, it depends on what kind of products are stamped; Thicker materials will have indentations on the edges, which will lead to deformation; The use of the die will also have an impact. More stamping times and poor interface of the die will lead to material deformation.

The following analysis is summarized:

1. Mould: The frequency of being used is high, resulting in too much pressure and poor tool interface, which will lead to material deformation.

2. Die pad: The height, thickness, hardness and elasticity of the die pad will also cause the product to be deformed, too thick and too high during production; If it is washed for a long time, it will swell the knife die; When the cushion is too soft and too low, the material will shrink into the die, resulting in product deformation. Therefore, it is necessary to choose a suitable die pad.

3. Tension: There are some materials, such as some protective films. If the tension is too large, the extruded products will shrink, and the die-cutting products finally manufactured may also be deformed.

4. Thick materials, such as PVC and EVA, may have indentation on the edge during die cutting, which will also lead to the deformation of die-cutting products.

5. Small edge products or some irregular products will also lead to product deformation during the punching process. For those products that are difficult to make, it is difficult to achieve one-time molding, so we can design two-time molding or more sets of punching molding to meet the product requirements. Ordinary pad cotton can't be directly used for small holes or small margins, but glass glue or silica gel can be cut into the required shape and size and manually stuffed into the mold. If the laser knife die can't achieve the effect, it is necessary to consider using precision dies (etching dies, engraving dies, etc.). For some products that are difficult to make, it is difficult to achieve one-time molding, so it is possible to design two times of molding or more times of punching molding to meet the product requirements.

6, the angle of the knife, although this problem rarely occurs, generally as long as the specific size of the knife is controlled, there is no problem, but if the technology is not enough, there will still be accidents.
