Hello everyone, my name is chinasynergygroup. Today this article will tell you about the matters needing attention when punching aluminum materials. The aluminum material is soft and easy to break, and some aluminum alloy parts are often crushed, scratched, deformed, etc. during subsequent processing, which also causes the aluminum material to be expensive. In order to avoid wasting materials and save costs, we need to pay attention to two major aspects: 📷 Mold manufacturing: 1.Aluminum raw material should be coated with PE film to prevent aluminum scraps caused by bending of aluminum material, which will cause point injury and indentation. 2. For products with a large number of punches, even if there is one more engineering number, punching will be performed from back to back. 3. During the reverse folding, the aluminum material is particularly easy to crack. Make the crimping line wider or not even crimp the line. 4. Cut the edge of the aluminum piece with a slow wire. This can prevent burrs and blanking. Easy to high temperature, so the hardness of the punch should be above 60 ° as far as possible. Use SKD11 or more material, and do not work with poor quality punches such as D2. In stamping production: 📷

  1. In order to do a good job of stamping aluminum parts and reduce the defect rate, 5S must be done first, especially for cleaning the mold, punching table, etc., the mold must be clean and tidy to ensure no debris
  2. If the product has a large burr, it must be sent to the mold repair in time and follow up with the result.
  3. The die pushing block will produce aluminum shavings with the flattening. If it is not processed in time, the punch will bring these aluminum shavings into the stripping plate during punching, causing the punch to wear. Dispose of all aluminum shavings under the push block
  4. Aluminum parts are easy to pile up and become hot and hard. We can apply some pressure on the material when punching and cutting, so that it can play the role of heat dissipation and dredging, and then press.
