Problems that should be paid attention to in the process of metal stamping:

2. Cracking at the bottom of the part: The main reason for the cracking at the bottom of the part is poor plasticity of the material or excessive pressing of the die holder. The preventive measures are to replace the material with better plasticity or relax the holder.
3. Wrinkles on the side wall of the part: The main reason for the wrinkle on the side wall of the part is that the thickness of the material is insufficient (thinner than the minimum allowable thickness) or the upper and lower molds are eccentrically installed, resulting in a large gap on one side and a small gap on the other side , The preventive measures are immediate replacement of materials and readjustment of molds.
