1. Cut the material
According to the drawing requirements and customer requirements to determine the size and thickness of the sheet; Cut the sheet to the desired size; When cutting, pay attention to controlling the flatness and verticality of the edge of the plate (if it is necessary to splice, the joint gap should be considered).

2. Open the material
According to the requirements of the design drawings, the corresponding holes on the plate are cut out and marked; Fine cutting of the open holes (such as drilling), its accuracy meets the requirements of the design drawings. At the same time, attention should be paid to avoid affecting the aesthetics of the box assembly due to the opening error.

3. Bend
The cut steel plate is bent and formed according to the Angle designed on the drawing, and attention should be paid to the uniformity of the thickness of the steel plate and the flatness of the plate; For curved or conical edges and corners, special tools should be used to manually trim and smooth, and then arc welding can be firmly welded. When bending, pay attention to protect the mold from damage and maintain a good operating environment to avoid unnecessary losses.

4. Stamping
The blank of the stamped box is put into the press to press it to get the desired shape and size; After the molding is completed, it should be taken out in time to check whether deformation occurs and corrected in time to achieve the quality pass rate of the product. In the process of molding, special attention should be paid to prevent scratching the surface of the workpiece and the occurrence of splashing and scalding accidents.

5. Welding

Argon arc welding equipment is used to spot weld the main parts of the box (generally 4); Then carbon dioxide gas shielded welding equipment is used to fully weld between it and the shell to achieve a better sealing effect; Finally, after grinding and polishing process, the production process of a finished box can be completed.

6. Spray oil
Before spraying, it is first necessary to remove the oil and other impurities on the surface of the workpiece before spraying paint, otherwise it will cause the phenomenon of paint film falling off, and pay attention to the selection of appropriate paint varieties to ensure the use of the effect. When spraying, the construction should be carried out in strict accordance with the operating procedures to avoid unnecessary waste and pollution of the environment.

According to the drawing requirements and customer requirements to determine the size and thickness of the sheet; Cut the sheet to the desired size; When cutting, pay attention to controlling the flatness and verticality of the edge of the plate (if it is necessary to splice, the joint gap should be considered).
