What are the obvious defects on precision stamped parts

Although the precision stamping parts market in China is currently very complete and there are many varieties of precision stamping parts on the market, the supply of precision stamping parts in China exceeds demand, and the competition in the market is fierce. In addition, there are still some quality problems with China's hardware stamping parts.

1. Scratches on Metal Stamping parts

The main reasons for scratches on parts are: sharp scratches on the mold or metal dust falling into the mold. The preventive measures include grinding the scars on the mold and removing metal dust.

2. Cracking at the bottom of the component

The main reasons for cracking at the bottom of the parts are poor plasticity of the material or excessive compression of the mold edge ring. The prevention method is to replace the material with better plasticity or loosen the edge ring slightly.

3. There are wrinkles on the side wall of the component

The main reasons for wrinkles on the side walls of parts are: the thickness of the material cannot be reduced (even thinner than the minimum allowable thickness) or there is eccentricity during the installation of the upper and lower molds, resulting in a large open space on one side and a small open space on the other side. The preventive measures include immediate replacement of materials and readjustment of molds.

4. The height of the parts is not allowed
