The electrostatic powder coating works by dispersing the powder, and the liquid electrostatic coating is atomization, but the two ways are almost the same. The electrostatic powder coating Beforehand coating needs to clean the surface of oil 、dust、rust and others, also painting the protection of the layer on the surface of the phosphorus、chromizing， or passivation.

when the electrostatic powder coating is ready in the machine, the gun coating out the particles of powder on the finish, which will have load electric scatter on the particle and affect by air flow(or centrifugal force or others ) and electrostatic then automatically coating on the finish.

Lastly, it is through the oven to cure the finish, which step makes the particle of powder melt the finish average. This step according to the quality of the material to set the temperature, normal material could be set around 200℃, or some special Low-temperature material just around 160℃.

The above are the steps for electrostatic powder coating, which can reduce the pollution of the environment and is good for the economic.
