What should be done if die-cut products deform during the processing? This is one of the problems that many technicians encounter. At this time, the first thing that technicians need to do is not to investigate whose fault it is, but to promptly identify the problem and then find the corresponding solution. So today, let's explore together with Suzhou Kedou Precision what exactly causes the deformation of die-cut products?
   First, it is necessary to see what kind of product is being stamped; Thicker materials will have indentations at the edges, which will lead to deformation. The use of the die also has an impact. If the stamping times are too many and the die interface is not good, it will cause the material to deform.
The following are several points of analysis summarized:
1. Mold: If it is used frequently and generates excessive pressure, and the interface of the knife is not good, it will cause the material to deform.
2. Die-cutting pad: Die-cutting pads have height='auto' rea, thickness, hardness and elasticity. During production, they can also cause product deformation, being too thick or too tall. If you rush for too long, the die-cutting mold will expand. If the pad is too soft or too low during the punching process, the material will shrink into the die, causing the product to deform. So it is necessary to choose a suitable die-cutting pad.
3. Tension: For some materials, such as protective films, if the tension is too high, the pressed products will shrink, and the final die-cut products may also deform.
4. Thicker materials, such as pvc and eva, may have indentations on the edges during punching, which can also lead to deformation of die-cut products.
5. Small-edge products or some irregular products may also deform during the punching process. For these difficult-to-make products that are hard to achieve in one go, a two-time or more nested punching design can be adopted to meet the product requirements. For small holes or small margins, ordinary cotton pads cannot be used directly. Instead, glass glue or silicone can be cut into the required shape and size and manually inserted into the mold. If the laser die-cutting fails to achieve the desired effect, it is necessary to consider using precise molds (such as etching molds, engraving molds, etc.). For some difficult-to-make products that are hard to achieve in one go, a two-time forming or more sleeve punching forming can be designed to meet the product requirements.

6. The Angle of the knife. Although this issue rarely occurs and is generally fine as long as the specific dimensions of the knife are well controlled, accidents can still happen if the skills are not up to par.
