What to pay attention to when processing aluminum stamping parts

Stamping parts are a kind of metal products that are widely used. The application industries include automotive, medical, 3C electronics and so on. Aluminum stamping parts are stamping parts made of aluminum materials, which are also very common in life. When stamping processing plants produce aluminum stampings, they need to be familiar with the characteristics of aluminum materials and how to ensure that they avoid undesirable phenomena during the stamping process. Now, Precision has summarized some matters needing attention in the production of aluminum stamping parts through summing up its years of customized processing experience. 1. The aluminum material is soft and easy to stick to the mold, so when designing the mold, leave enough gaps, leaving the gap to 10% of the thickness of the side material (straight edge of the blade), and the taper is 0.8-1 degrees; 2. As aluminum material is brittle and easy to break, especially in the case of reverse folding, please try not to press the line. Even if you want to do this, you should make the crimping line wider and shallower; 3. When processing aluminum stampings, you need to cut the cutting edge with a slow-speed steel wire to prevent burrs and blanking. Aluminum stamping parts are prone to high temperatures, so the hardness of the die used needs to be higher than 60 degrees, and it should be SKD11 material or higher; 4. If the stamping parts processing plant wants to deal with aluminum stampings well and reduce the defect rate, then It needs to be cleaned first, including molds, punches, assembly lines and packaging materials, to ensure that there is no dirt and sharp debris.
