Electro-static powder coationg is to spray the powder paint to the product through electro-static processing and to roast for some time to form coating.Electro-static spraying equipment - electro-static plastic spraying machine is used to spray the powder paint to the workpiece surface.Under the efect of static, the powder will be adsorbed onto the workpiece surface.Thus powder coating is formed.Through flowing and solidifying under high temperature, the powder coating will become different finial coating.
