Features of Sheet Metal Stamping Parts

According to the process classification, sheet metal stamping can be divided into two categories: separation process and forming process. The separation process is also called punching, and its purpose is to separate the stamping parts from the sheet material along a certain contour line, while ensuring the quality requirements of the separation section. The surface and internal properties of the sheet metal stamping sheet have a great influence on the quality of the stamped finished product, requiring accurate and uniform thickness of the stamping material. The surface is smooth, without spots, scars, abrasions, surface cracks, etc. The yield strength is uniform, without obvious directionality, and the uniform elongation rate is high. The yield ratio and the work hardenability is low.


Advantages of sheet metal stamping

The stamping parts are mainly stamping the metal or non-metallic sheet material through the stamping die by the pressure of the press. It has the following characteristics:

1. Stamping parts are manufactured by stamping under the premise of low material consumption. The parts have light weight and good rigidity, and after the sheet metal is plastically deformed, the internal structure of the metal is ameliorated, so that the strength of the stamping part improved.

2. The stamping parts have high dimensional accuracy, are uniform with the size of the mold parts, and have good interchangeability. Without further mechanical processing, it can meet general assembly and use requirements.

3. During the stamping process, since the surface of the material of the stamping part is not damaged, it has better surface quality, smooth and beautiful appearance. This provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.
