Who knows the production process of tin file cabinets

1, shear plate: shear plate as the name implies is the manufacturer to buy back the steel plate in the shearing machine according to the size of the tin cabinet for cutting, regular cabinet cutting faster, customized special size of the cabinet will need to adjust the machine and then cut the plate.

2, bending: bending means that the cut sheet according to the shape of the cabinet for bending, need to be bent on the bending, do not need to go directly into the next production process, generally in the larger factories are assembly line operation, even if the special size, only need to modify some data on the computer.

3, spot welding: this process is to be done before the things spliced together, such as the top plate, side panels, door panels, etc., and then the use of non-trace welding machine in the splicing mouth welding, and finally the entire tin file cabinet prototype has come out, and then you can enter the next process.

4, pickling, phosphating and other treatments: in the pickling, phosphating this step is mainly to remove the iron surface grease, rust and other substances, so that it is smooth and flat.

5, plastic spraying: now the production process, some large manufacturers use electrostatic powder spraying technology, so that the products do not have odor, there is no toxic gas volatilization, more environmentally friendly, of course, some of the small manufacturers use or spray paint or baking paint, this process is more outdated, inefficient and bad for the body and the environment have a bad influence.

6, heating: generally sprayed products need to be heated at high temperatures, otherwise the spray powder is easy to hang off, after about 200 degrees Celsius of high temperature heating, the product can be packaged directly out of the factory.
