Automatic gun is capable of automatic spraying raw spraying device, spray suitable for small objects, easy to apply to the hardware, toys, plastics, furniture, handicrafts, wood products, such as spraying, its main feature is simple in structure, easy to operate, change color, the sector size of the face of the spray rate can be adjusted with the geometry of the workpiece to be coated, good atomizing effect
Automatic gun internal having a pneumatic piston mechanism, above the piston is equipped with a stainless steel needle, the rear piston is provided with a group of high-tension spring, when the compressed air to stop the supply, the spring piston and the needle forward withstand thiswhen the needle and the nozzle to block the passage of liquid to a tight fit of the high precision, to the contrary, when the compressed air supply, the pressure of the compressed air piston pushed, between the needle and the nozzle so that voids allow liquids discharged,after the liquid is discharged immediately in contact with air and atomized produce atomization.
The gun should be selected note filled filled mainly from the primer coating, increasing the role of the thickness of the coating, so the particle size of the primer is greater, viscosity, a larger proportion, the emphasis on the amount of paint to be larger, so the sprayingthe primer gun should the nozzle, to a large caliber, and below the reservoir but also a large number of paint cans. Topcoat, the degree of atomization, and are often used in smaller diameter, while atomization good gun. Commonly used gun nozzle with a different caliber, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm , 2.5 mm various models can be selected based on the size of the object to the spray paint and spray. For example: diameter 2.0 -2 · 5mm's often used to coarser spray viscosity primer or a large area spraying; caliber 1.5 -1 · 8mm, mainly used to spray the topcoat; caliber 0 · 6-1 · 3mm, mainly used for spraying small parts or crafts.
