The steel filing cabinet, also called the metal filing cabinet, is a cabinet made of cold-rolled steel sheets through a complete and precise production process, mainly for the placement of documents, materials and various archives. Generally applicable to companies, schools, factories, and various training institutions. The manufacturing process of this item is not very complicated. Let us introduce the manufacturing process.

 

1, cutting material

 

The required size of the pre-treated steel sheet (cold-rolled steel sheet) is cut out by a shearing machine, and the back panel, the side panel, the top panel, the door panel, the body, the laminate, and the like of the filing cabinet need to be opened. The so-called cutting is the initial shape required to cut the file cabinet first.

 

2, bending

 

Using the bending machine to make the inner and outer folds of the cabinet, these are the connecting parts of the subsequent process, and also the key step in the manufacture of the file cabinet. If the bending is not done well, the steel file cabinet will easily weld the quality. Up to standard, directly affects the quality and service life of the cabinet, and in serious cases, the joint will fall off.

 

3, welding

 

Electromechanical welding with electric welding, the purpose of the process is to strengthen, improve the quality of the file cabinet, and the place where the bending is not easy to fall off.

 

4, polishing

 

After the file cabinet is welded, there will be burrs caused by welding 2. The polishing is to smooth the burrs. The purpose of this process is to make the file cabinet beautiful and easy to scratch when used.

 

5, phosphating

 

The rust removal treatment is carried out after pickling.

 

6, spray paint

 

The semi-finished product enters the painting booth for electrostatic painting.

 

7, assembly and inspection

 

After assembly, it can be used after passing the inspection.
