Powder paint gun for cars

Powder coating is a great way to create a powder coating on metal that will extend the life of your products and make them look very attractive. Car manufacturers have long only used powder paint to coat car parts. Over the years, they have made sure that only it allows you to maximally protect the car from reagents that are sprinkled with earth, water, ultraviolet radiation in winter and minimize the visibility of mechanical damage.

In order to apply powder coating, you need to have a spray gun, a spray chamber and a polymerization oven. What should be the gun for painting cars so that the coating is of the highest quality, let’s figure it out further.

Pistol for auto

The principle of the spray gun is that it electrifies paint particles. This is because the entire powder coating process takes place thanks to the electric field. The paint is not just applied to the surface, it seems to be magnetized. Therefore, the powder directly penetrates into the upper layers of the product and is fixed in it. This ensures maximum coating strength.

Sprayers are tribostatic and electrostatic. And before you buy a gun for painting a car, you need to figure out what the difference is, and which one is suitable for the needs of production.

Tribostatic pistol

The tribostatic nebulizer charges particles by friction. It happens like this: from a tank with powder paint, powder particles enter the barrel of the gun, mix with air, rub against each other and against the gun on the way to the nozzle, and are charged. Inside, the pistol body has macroroughness Therefore, the paint experiences a strong effect of frictional forces, and its charge becomes even greater.

In this case, the tool must be grounded.

These pistols are inexpensive. But if the room is cold, they become less effective. In addition, not all powders can be applied in this way. Only high quality epoxy powders are suitable for tribostatics.

The performance of such a sprayer depends on the size of the paint tank. In this case, the charge becomes less intense when there is little paint in it.

These guns are suitable for painting small items.

Electrostatic gun

Structurally, an electrostatic atomizer is more complex than a tribostatic one. In this version of the pistol, particles are forcibly charged by an external source.

Because of this, such a gun sprays any paint with the same quality.

An electrostatic car paint gun, which is more expensive than a tribostatic gun, is ideal for painting large flat parts with simple shapes. For example, it works well for painting a car frame.

In large factories that regularly paint a large number of car parts, automatic powder coating lines are installed. Only she can provide maximum quality and speed of coverage of automotive parts. In addition, automatic painting minimizes the risk of human-induced coating defects. You can buy a gun for car painting in Smartline.
