Many consumers want to know the specific manufacturing process of the file cabinet when purchasing a file cabinet. However, if they want to see it with their own eyes, they have to go to the file cabinet manufacturing factory. Therefore, for many consumers, the metal file cabinet manufacturing process process, do not know. So today, I will share with you the specific process of the steel file cabinet manufacturing process, so that everyone can have a deeper understanding of the file steel cupboard.
Before introducing the manufacturing process flow, let me tell you about the tools required for manufacturing. The manufacture of iron file cabinets mainly relies on tools such as shearing machines, folding machines, punching machines, acid-base pools, welding machines, electrostatic sprayers, etc. With the help of these tools, the file cabinets are made more high-quality. In addition to the tools required for manufacturing, the raw materials required for the manufacture of iron filing cabinets are cold-rolled sheets and electrostatic spraying powder. In addition, the building of the cabinet also needs the support of accessories, such as locks, door handles, door activity pages and so on.
In addition to a brief introduction to the tools, raw materials and accessories for file cabinet manufacturing, the following is the specific manufacturing process:
1. Design. Many people always ignore this step when introducing the manufacturing process of file cabinets. In fact, after the customer inquiries and requests, the file cabinet manufacturer must design according to the customer's requirements, and the design content includes size, space and color. , appearance, etc. This is the first step before manufacturing.
2. Open the material. Use the shearing machine to reduce the required size of the cold-rolled steel sheet. Different customers, different requirements, different styles, etc., the size of the cut steel sheet is different.
3. Stamping. This item has relatively high technical requirements. The cut steel plate is punched out of the corner edge and handle position with a punching machine. In fact, different positions on the file cabinet have different styles of chamfering. For example, the door panels and side panels of the file cabinet, the top and bottom panels are different. Generally, for large file cabinet manufacturers, corner removal is an assembly line operation.
4. Bend. Use the folding machine to fold the inner and outer folds. Similarly, the bending is different in different positions of the file cabinet.
5. Spot welding. When all the bending is done, spot welding with an electric welding machine. Large manufacturers use a non-marking spot welding machine. The surface of the pointed file cabinet is flat and does not need to be polished again. At this point, the cabinet as a whole is ready.
6. Pickling and phosphating. Spot-welded file cabinets are subject to acid-base bath for pickling and phosphating treatment, which can remove grease and rust spots on the surface of the plate and prepare for spraying.
7. Spray. The pickling and phosphating file cabinets are placed in the spraying workshop to complete the spraying process. This process uses electrostatic powder spraying, which is not only smooth and clean, but also environmentally friendly. Generally, the painted file cabinet is heated at high temperature.
8. Assemble and form. When the spraying is completed, the file cabinet can be transported to the assembly workshop for assembly. After the partitions, slides, drawers, door panels, locks, etc. are assembled, the quality inspector will test and the finished products can be packaged after passing the test.
