Before producing and processing aluminum stamping parts, stamping factories need to be familiar with the characteristics of aluminum materials and how to ensure the prevention of adverse phenomena during the stamping process

1. Aluminum material is relatively soft and the mold is easy to block, so when designing the mold to place gaps, it is advisable to place gaps with edge material thickness of 10%. A straight depth of 2mm is more suitable for the cutting edge, and a taper of 0.8-1 degrees is suitable;

2. Due to the brittleness and easy cracking of aluminum materials, especially in the case of reverse folding, it is advisable not to do wire pressing. Even if it is necessary, the wire pressing should be made wider and shallower; 3. When processing aluminum stamping parts, stamping factories require slow wire cutting for the cutting edge to prevent burrs and uneven material dropping. Aluminum parts easily generate high temperatures, so the hardness of the mold punch used should be above 60 degrees, and at least SKD11 material should be used;

4. In order for stamping factories to process aluminum stamping parts well and reduce the defect rate, the first step is to clean them, including molds, punch tables, assembly lines, and packaging materials. It is necessary to ensure that there are no sharp objects or dirt.
