Features: Spraying operation has high production efficiency and is suitable for manual operation and industrial automation production. Widely used in hardware, plastics, furniture, military industry, ships and other fields, it is the most widely used painting method at present.

Spraying operation needs a clean workshop, and the environmental requirements range from one million to one hundred. Spraying equipment includes spray gun, spray booth, paint supply room, curing oven/drying oven, spraying workpiece conveying equipment, defogging and waste water and waste gas treatment equipment.

The main problems in spraying are highly dispersed paint mist and volatile solvents, which not only pollute the environment, but also waste paint and cause economic losses.

Classification of spraying methods:

Manual spraying is to spray oil directly on the surface of products through front-line operators, and now it is used for manual spraying of defective products after automatic spraying.

Automatic spraying fixes the product to be sprayed on a rotatable bracket, and then locks the bracket on the assembly line. Through the movement of the assembly line and the continuous rotation of the rotatable support, the uniform spraying of the product surface 100% has been achieved.
