Aluminum veneer processing

There are two kinds of aluminum veneers in the world, such as fluorocarbon sprayed aluminum veneers and roller coatings. There is no roll coating production line in China, so the processing of veneers here is mainly about the production of fluorocarbon coating. Spraying aluminum sheets is divided into two major steps: the first step is sheet metal processing. This process mainly processes the aluminum veneer into the shape and size required for construction by cutting, folding, bending, welding, and grinding the flat plate. The second step is spraying. Spraying is to spray paint on the processed sheet metal. There are two types of spraying, one is manual spraying and the other is machine spraying. Machine spraying is generally only suitable for regular flat plates, but this kind of aluminum veneer is used less in actual use, and manual spraying is adopted by most domestic manufacturers. Manual spraying is a dangerous job because the paint is highly volatile and toxic, and it is easy to cause chronic benzene series poisoning, which seriously affects people's health. One of the great advantages of manual spraying is that regardless of the amount of color, the color can be optional, and the roll coating of the aluminum-plastic panel must reach a certain amount before processing. The processing process of aluminum-plastic composite board is more complicated than that of aluminum single-board, mainly consisting of four processes of forming, painting, compounding and trimming. These four processes are automated except for trimming. It can be seen from the processing process that the aluminum-plastic composite panel has certain advantages in environmental protection and safety. Coupled with the ease of sheet metal processing of aluminum veneers, some private workshops have begun to get involved, seriously affecting the stability of the market quality of aluminum veneers.
