Three elements for choosing an automatic spray gun

Automatic spray gun is a common hardware automatic tool, mainly used for spraying paint, coatings, etc. There are many brands and models of automatic spray guns on the market. We need three main elements when purchasing automatic spray guns.

1. Cost-effective

Multi-party inspection of product quality and production and distribution manufacturers is the primary link in purchasing products, such as their business history, market share and service network. Brand automatic spray guns are generally reliable in quality, but the brand effect often makes their prices high. The prices of domestic similar products are usually lower, but their quality and after-sales service are often worrying. Therefore, focus on cost performance, or performance first, brand first.

2. Atomization effect

A good paint spray gun usually has uniform atomization, stable paint flow, and high paint utilization rate. On the one hand, the atomization effect of the paint spray gun is related to its internal channel design and the accuracy of the aperture on the nozzle and air cap, and on the other hand, it is also related to the working air pressure. Experienced masters know that brand automatic spray guns usually have better atomization effect than non-brand guns, and high-pressure spray guns usually have better atomization effect than low-pressure spray guns. The reason is that the production process and equipment of brand spray guns are more advanced, with higher precision and stricter quality inspection. The high-pressure spray gun has good atomization because its working pressure is high, but the air consumption is large, and the paint utilization rate is low.

3. Durability

The durability of the paint spray gun mainly depends on the material it uses. A good automatic spray gun material has sufficient pressure resistance and light weight, as well as high-quality outer protective layer and internal parts. Many domestic spray guns or foreign non-brand low-cost spray guns have good spraying effects at the beginning, but after one or a few months of use, the nozzle or air cap aperture becomes larger, or the needle is worn and cannot continue to be used, etc., which are the properties of the materials used. Insufficient; there are also cases where the coating on the surface of the spray gun falls off after several times of contact with the thinner, which affects both the vision and the feel of use, which is related to the poor surface material or the level of the electroplating process.
