The man-machine material ring is the five elements of stamping processing. Today we will introduce the material, that is, the raw material. When the quality of metal raw materials is not up to standard, what problems will there be when producing rectangular parts? Stamping manufacturers must pay attention to prevention.

1. The thickness of the raw material is not up to standard, which can lead to poor inner diameter and mold contusion;

2. The surface of the raw material is corrugated, which can cause the metal stamping and drawing parts to wrinkle;

3. The surface of the raw material is rusted, and the stamping produced is also rusted;

4. The surface of the raw material has pits and bumps, and the stamping and drawing parts produced by the application have poor appearance.

What technical standards must the metal stamping raw materials meet for production in the factory, what are the performance parameters of the stamping raw materials, control the cost of metal drawing aluminum parts from the raw material level, etc.
