Although China's Stamping Parts market is very perfect at present, there are many types of stamping parts on the market, but the supply of stamping parts in China is oversupply, the competition in the market is fierce, and there are still some quality problems in metal stamping parts in China.

1. Scratches on metal stampings

The main causes of scratches on the part are: sharp scratches on the mold or metal dust falling into the mold. Avoid the problem of scratching the mold and removing metal dust.

2, the bottom of the part is cracked

The main reason for cracking at the bottom of the part is that the material is poorly plasticized or the die bead is too tight. Avoid the problem of replacing plastically good materials or relaxing the crimping ring.

3, the side of the Metal Stamping Parts has wrinkles

The main causes of wrinkles on the side wall of the part are: the thickness of the material is not (thicker than the minimum allowable thickness) or the eccentricity of the upper and lower molds is installed, and the gap is large on one side and small on the other side. Avoid the problem of replacing the data and re-adjusting the mold.
