Spray gun realizes automatic remote to convey and spray liquid coating with the he negative pressure is produced by the sudden expansion of the compressed air in the spray nozzle: it is classified into two types: two-position self-suction adjustable double-pipe spray gun, and two-position self-suction adiustable composite-pipe spray gun.
The atomization quantity and area of the double-pipe spray gun are adjustable, while both the gas discharge an atomization quantities of composite-pipe spray gun are adjustable. The gas discharge position is used for the uniform drving of the coating by blowing and forthe removal of the mold residues, while ihe liquid discharge posiftion is used for the spraying of the liquid coating.
