The HDA hight speed rotating bell spray system good efficient used in various industrial, atomize the paint into extremely fine particles, and through the role of electrostatic field to make the particles charged, and then quickly adsorbed to be coated on the workpiece, forming a uniform, flat and smooth coating. This technology has the advantages of high paint rate, less paint waste, less environmental pollution, stable product quality, etc., and can reduce cleaning and maintenance costs, improve production efficiency and safety.
