The manufacturing process of supermarket shelves involves several steps, the following is the detailed manufacturing process:

1:Design stage: First of all, it is necessary to determine the height, width, depth and load-bearing parameters of the shelf according to customer needs and practical application scenarios, and develop detailed drawings and technological processes.

2:Materials procurement: According to the design requirements to purchase the appropriate materials, commonly used materials are mainly cold-rolled steel, galvanized steel pipe, etc., and ensure that the specifications, quantities and other information of the material meet the standards.

3:Cutting and stamping: The purchased materials are cut according to the requirements of the design drawings, and then the sheet is stamped out of the required shape, such as the shelf bottom plate, side plate, etc., to ensure the accuracy of the size and the consistency of the shape.

4:Welding and assembly: After cutting and stamping the parts, they are welded by welding machines to connect the plates into a complete shelf frame. The welding process needs to ensure the solidity and stability of the welding points. After the welding is completed, the parts of the shelf are assembled through screws, nuts and other connectors to form a finished shelf.

5:Surface treatment: The surface treatment of the shelf generally includes rust removal treatment, and then spray or galvanized treatment. Spray the shelf anti-corrosion and beautification treatment, you can choose different colors of paint for painting; Galvanizing is to improve the anti-rust performance of the shelf by plating a layer of zinc on the surface of the shelf.

6:Spraying process: The spraying process includes degreasing (removing oil), washing (removing residual alkalinity), physical derusting, washing, acid-base synthesis, washing, phosphating (forming phosphating film), washing, passivation (removing residual impurities), washing, drying, electrostatic powder spraying, supplementary spraying, 180 degree high temperature curing for 20 minutes, air drying, inspection, packaging storage and other steps.

7:Quality inspection and packaging: Quality inspection personnel will inspect the finished product shelf to ensure that the quality meets the standards and requirements. Packaging workers will assemble and pack the shelves, adding protective materials, such as foam, cardboard, etc., to ensure that the shelves are not damaged during transportation. At the same time, it will also be labeled and labeled to facilitate purchase and user search.

The above steps make up the main manufacturing process for supermarket shelves, and each step has an important impact on the performance and quality of the final product.
