1. The performance of the equipment is mainly powder-feeding rate and powder-feeding ability for powder-spraying equipment, and the processing ability for complex workpieces. This index is difficult to understand by friends who first contacted. We must carefully understand it. Comparing the powder-feeding ability of the built-in high-pressure electrostatic spraying machine is much higher than that of the high-pressure external products. In addition, the powder-feeding ability of different manufacturers is much higher. The performance of the same kind of product often has a big gap; the performance of spray gun can not be understood only by inquiring about parameters such as static voltage, charging current, etc. These parameters can not be verified by users, and are often false, so it must be judged by obvious spray test of special workpiece.

2. The stability of equipment quality, the working environment of industrial processing equipment is no better than that of home appliances, sometimes the environment is very poor, and often work continuously for a long time without shutdown, so the stability of equipment is very important.

3. Technical service and after-sales service, many customers need the guidance of technical experts with rich production experience to master electrostatic powder spraying (plastic spraying technology) smoothly, while the general equipment salesman can not meet such requirements, can only roughly teach customers how to use it.
