1. Stamping parts have high dimensional accuracy, uniform dimensions of the same mold parts, and good interchangeability. No further machining is required to meet general assembly and use requirements.
2. Cold stamping parts generally do not undergo cutting processing, or only require a small amount of cutting processing. The accuracy and surface state of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting processing is small.
3. During the stamping process, the surface of the stamping parts is not damaged, so they have good surface quality and smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.
4. Stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity. After the sheet material undergoes plastic deformation, the internal structure of the metal is improved, which improves the strength of the stamping parts.
