    Powder spraying is a method using machines to give powder electrostatic and then the powder is evenly sprayed on the surface of the workpiece. After spraying, it is heated and solidified by a curing furnace to form a coating film. Electrostatic powder Spraying is widely used as a metal decoration technology. Through this technology, it is easy to get a high thickness of film to get a strong rust resistance and beautiful appearance. Besides, different colors of surface coating isworkable and available.
