How to choose the automotive primer spray gun?

For the automotive primer painting, effect, the quality of the automotive paint is absolutely an important part, but at the same time, we must understand that the choice of automotive primer spray gun is also an important part. So how should we choose an automotive primer spray gun?

Automotive spraying is divided into two conditions. One is in the manufacturing process to paint, and the other is the use of the car after the appearance of scratches. These two conditions have different usage of the automotive spray gun.

I. Auto original spraying

The original spraying of the car has to go through many steps, using generally high-temperature automotive paint. If the whole car is sprayed then a pressure feed spray gun is generally used. This spray gun does not have a pot on top, it has a paint inlet and draws paint from a separate paint can. When adding pressure to the paint can, several automotive spray guns can be supplied with paint at the same time. In the case of complete automotive painting, the volume of paint required is high, so a pressure feed gun is suitable for high volume and continuous painting operations.

In the case of off-line repair, a gravity spray gun is generally used. This type of automotive spray gun is mainly for small area repair, mainly relying on its own gravity and the negative pressure between the nozzle and the paint sprayed out, and then the paint atomized in the air. If the amount of spraying is small, the spraying area is small, and also need to change the color often, then you should use this kind of car gun.

II. Auto repair spraying.

The repair is divided into three main conditions. The first is topcoat spraying. When spraying, the worker can spray economically and also can spray with high flow, or choose to low flow and medium air pressure spraying. In general, specifically for topcoat auto spraying gun is used by workers. 

The second is for small repair spraying. At present, there are spray guns for primer spraying, color paint spraying guns, clear coat spraying guns, and small repair spraying guns in auto 4S stores.
