After die-casting, the paint is atomized by a spray gun and coated on the surface of the object. There are many types of compressed air spray paint, high pressure airless spray paint, and electrostatic spray paint. The paint spraying operation uses flammable paints containing a large amount of solvents. The solvent vapors that volatilize into the air under conditions that require rapid drying can easily form explosive mixtures. In particular, electrostatic spray painting is carried out at a high voltage above 60 kV, and the distance between the spray nozzle and the painted work piece is within 250 mm, which is prone to spark discharge and ignite flammable vapor.
There are currently four main types: arc spraying, flame spraying, plasma spraying and explosive spraying. Using spraying technology, coatings with wear resistance, corrosion resistance, heat insulation, electrical conductivity, insulation, sealing, lubrication and other special mechanical physical and chemical properties can be obtained on various substrates. The application range is very wide, involving various sectors of the national economy and various fields including cutting-edge technology.

There are currently two spraying methods

Hand spraying
The front-line operators directly spray oil on the surface of the product. Now it is currently used for manual spraying of defective products after automatic spraying.
Fully automatic spraying
The product to be sprayed is fixed on the rotatable support, and then the support is locked on the assembly line. Through the movement of the assembly line and the continuous rotation of the rotatable support, 100% uniform spraying on the product surface has been achieved.

The spraying operation has high production efficiency and is suitable for manual operations and industrial automation production. It has a wide range of applications, mainly in the fields of hardware, plastics, furniture, military industry, and ships. It is the most common coating method used today; spraying operations require environmental requirements There are dust-free workshops ranging from one million to one hundred, and the spraying equipment includes spray guns, spray booths, paint supply rooms, curing furnaces/drying furnaces, spraying workpiece conveying equipment, anti-fogging and waste water, waste gas treatment equipment, etc.
