The paint spray gun uses compressed air to atomize the paint into fine paint droplets, which are then sprayed onto the surface of the object under the influence of the air flow. When the compressed air is discharged from the air holes of the air hood, a negative pressure is formed at the paint nozzle, which exerts suction on the paint. Then, the sucked paint is sprayed out in the form of atomized paint under the action of the compressed air at the air holes in the air hood.

Manual paint spray gun: Common types include gravity type, pressure feed type, and suction type. The gravity type uses gravity to pull the paint from the pot above to the nozzle below, and then uses wind power to atomize and spray it out, which is suitable for small area repairs; the pressure feed type uses an external paint supply pump or pressure tank/pressure barrel to supply paint, and can supply paint to several spray guns at the same time, which is suitable for large areas or continuous operations; the suction type uses high-speed airflow to create a vacuum state in the spray gun, generating suction to suck the paint from the pot to the nozzle and atomize it for spraying, which is suitable for large-area spraying.
In the field of automobile manufacturing, on automobile production lines, paint spray guns are used to spray primer, topcoat and varnish on automobile bodies to ensure that the surface of the body is smooth and uniform in color, which plays a protective and decorative role. It can also be used to paint automobile parts such as bumpers and door interiors. It is used to repair and spray paint on scratches, wear and tear on the car body, as well as to refurbish the whole vehicle to restore the original appearance of the car. Spray guns are used to paint the surface of solid wood furniture, such as spraying varnish to protect the wood texture, or spraying colored paint to change the color of furniture, increase the beauty and wear resistance. Decorative paint can also be sprayed on the surface of artificial boards to simulate wood texture or provide various color effects, while playing a role in moisture-proof and scratch-resistant. Paint spray guns are used to spray plastic paint on the shells of electronic products such as mobile phones, computers, and televisions, which can protect the shell, increase the texture, prevent scratches and wear, and achieve different appearance effects.
FAQ
Q: What should I do if there is a splash or unevenness of paint mist when painting?
A: Check whether the nozzle is blocked, adjust the air pressure to the recommended range (usually 0.3-0.5MPa), keep the distance between the spray gun and the workpiece 15-25cm and move at a constant speed.
Q: How to properly clean the spray gun after use?
A: Immediately rinse the gun body, nozzle and tubing with the corresponding thinner, repeatedly pull the trigger to discharge the residual paint, and finally wipe dry and store in a dry place.
Q:Do I need to change the nozzle of the spray gun for different paints?
A: Need. For example, a large diameter (1.5-2.0mm) is used for latex paint, and a medium diameter (1.2-1.5mm) is used for clearcoat/base paint to prevent clogging or poor atomization.
