The basic principle of metal stamping processing is to use pressure to plastic deform the metal material, obtaining the desired shape and size. This process usually includes the following steps.

Firstly, choose the appropriate metal material. The material of metal stamping parts needs to have good plasticity and ductility, so that plastic deformation can easily occur during the processing. Common metal materials include steel, aluminum, and copper etc.

Secondly, design and manufacture molds. Mold is an indispensable tool in the processing of metal stamping parts. It is designed and manufactured based on the shape and size of the required product. Molds are usually made of high-strength alloy steel to ensure their durability and stability.

Then, place the metal material into the mold. This step can be completed through manual operation or automated equipment. Before being placed in the mold, the metal material needs to undergo pre-treatment, such as removing oxide layers and oil stains, to increase the material's adhesion and fluidity.

Next, apply pressure to cause plastic deformation of the metal material. This step is accomplished by using a stamping machine. Stamping machine is a specialized equipment for metal stamping processing, which can provide sufficient force to compress metal materials into the desired shape and size.

Take out the processed metal stamping parts. After stamping is completed, open the mold and take out the formed metal stamping part. At this point, there may still be some internal stress in the metal stamping parts, so subsequent treatments such as annealing or quenching are needed to eliminate internal stress and improve its mechanical properties.

In summary, the basic principle of metal stamping processing is to use pressure to plastic deform the metal material, thereby obtaining the desired shape and size. By selecting materials reasonably, designing and manufacturing molds, applying pressure, and carrying out subsequent treatments, metal stamping parts that meet the requirements can be produced.
