Background

The spray coating is a coating method of dispersing into uniform and fine droplets by a spray gun or a disc atomizer with the aid of pressure or centrifugal force and applying to the surface of an object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivatives of the above basic spraying forms, such as high flow low pressure atomized spraying, thermal spraying, automatic spraying, multiple spray groups, etc.

The traditional spraying method is manual spraying and consists of a compressed air pipe and a manual spray gun.

The traditional manual spraying mode cannot control the quality of the product only by means of the experience and visual sensation of workers because each spraying process parameter cannot be specifically and quantitatively controlled, the process standardization cannot be achieved, and the phenomenon of unstable product quality is serious.

Due to the structural characteristics of brake disc products, the brake disc products need to be turned over for many times in the traditional manual spraying process to finish spraying, and particularly, the production efficiency is extremely low when the brake disc products need to be sprayed completely.

Because the traditional manual spraying can not accurately adjust the spraying amount of the coating of the spray gun according to the different film thickness requirements of each plane of a product, the phenomenon of over-spraying is serious, and the coating is seriously wasted.
