The production process of metal shelves mainly includes the following steps:
1. Raw material preparation: choose suitable material types and specifications, and common materials include cold-rolled steel, etc.
2. Open cutting: according to the design requirements, raw materials are cut and equal to get the required shape and size.
3. punching: Use punch and other equipment to flush the required hole position on the material for subsequent assembly and connection.
4. Cold rolling forming: forming the material by cold rolling mill and other equipment to achieve the required shape and size.
5. Rule and flat head: adjust the size and head of the shelves after forming to ensure the dimensional accuracy and flatness.
6. Welding: Use the welding machine and other equipment to weld and connect each part to form a complete shelf structure.
7. Correction: correct the welded shelf to ensure the dimensional accuracy and stability of the shelf.
8. Surface spraying: surface spraying treatment on the shelves to increase their corrosion resistance and aesthetics. In the process of spraying, degreasing, washing, phosphorization and other pretreatment, and then electrostatic powder spraying, constant temperature curing and other steps.
9. Packaging: The finished shelves are packaged to protect the surface from damage and to facilitate transportation and storage.
10. Inspection of finished products: inspect the packaged finished product shelves to ensure that their quality meets the design requirements. Through the above steps, the metal shelves can be produced. In the production process, the quality and accuracy of each step need to be strictly controlled to ensure the quality and stability of the final product.
