Sheet metal stamping is a common processing technology, which is mainly used to produce various shapes of metal parts. Sheet metal stamping process includes the following contents:

1. Cutting: Cut the metal plate into the required shape with a shearing machine.

2. Punching: Punching holes arranged in patterns on the metal plate with a punching machine to facilitate the assembly and fixing of parts.

3. Bending: Bending the metal plate into the required shape along a certain bending line with a bending machine.

4. Deep drawing: Drawing the metal plate into the required shape with a deep drawing machine.

5. Die-casting: put the metal plate into a die-casting mold and extrude it into the required shape through high pressure.

6. Welding: Metal parts with different shapes are connected by welding process to form a complete product.

7. Surface treatment: carry out surface treatment on sheet metal products, such as spraying and coating, to protect the surface of the products and improve the aesthetics of the products.

These processes usually require the use of professional sheet metal stamping equipment and tools to ensure machining accuracy and production efficiency.
