Stainless steel sheet metal processing actually refers to the production and processing of cutting, folding, and grooving of stainless steel and other metal plates. Compared with forging, stainless steel castings and stainless steel sheet metal machined parts have the advantages of light weight, saving metal materials, simple processing technology, reducing production costs, and saving production costs. However, if we want to achieve good quality of stainless steel metal sheet processing parts, it is inseparable from its processing process. So do you know what the processing process of stainless steel metal plates is?

Stainless steel sheet metal processing technology:

1. Blanking:

After selecting the cutting material, proceed to the next process and proceed to the corresponding process according to the requirements of stainless steel sheet metal processing.

2. Spray treatment:

After bending stainless steel sheet metal parts, riveting and other processes are completed, surface treatment should be carried out. The surface treatment methods for different plates are different. After cold plate processing, the surface is generally electroplated, and there is no need for spraying after electroplating. Others are usually treated with vulcanization and sprayed after phosphating. Electroplated plates require surface cleaning, degreasing, and then spraying.

3. Bending:

When processing and bending stainless steel metal plates, the tools and grooves used in the bending process should be determined based on the dimensions and material thickness on the drawing. The key to selecting the upper mold is to avoid deformation caused by collision between the product and the cutting tool, and the selection of the lower mold should be determined based on the thickness of the sheet metal. In order to weld firmly, the protrusions and protrusions on the workpiece that need to be welded should be in uniform contact with the flat plate before welding to ensure consistency in heating at each point.

4. Assembly:

After bending and spraying, the assembly process should be carried out. Before assembly, the protective stickers used in the original spraying should be removed to ensure that the threaded holes in the parts are not coated with paint or powder. Throughout the process, wear gloves to avoid dust from your hands adhering to the workpiece. If there are debris or dust on the workpiece, it needs to be blown clean before entering the packaging process.

5. Surface treatment:

Surface treatment generally includes phosphating film, electroplating of colorful zinc, chromate, baking paint, oxidation, etc., Phosphate coating is generally used for cold rolled and electrolytic plates, and its main function is to coat the material surface with a protective film to prevent oxidation. Then, it can enhance the adhesion of its paint, and electroplating colored zinc generally uses cold rolled sheet surface treatment; The surface treatment of chromate, aluminum plate and aluminum profile generally adopts oxidation; Select specific surface treatment methods according to customer requirements.

6. Assembly:

Assembly is the final step in material completion. If the material cannot be used due to scratches, rework is required, which will waste a lot of processing time and increase material costs. Therefore, special attention should be paid to the protection of materials and parts.

In summary, it is a stainless steel sheet metal processing process. It is worth noting that the surface treatment methods for stainless steel sheet metal machined parts during production processes such as edge folding and riveting vary depending on the material used. Usually, the surface electroplating process should be carried out after cold plate production and processing, and there is no need for coating processing after the electroplating process.
