Abstract:
An electrostatical powder coating method and apparatus therefor, in which an auxiliary electrode is disposed in the vicinity of a desired coating surface of an object to be coated, a gun for performing electrostatically powder coating is directed to the object to be coated and the auxiliary electrode, a DC electric field is formed between the gun, the auxiliary electrode and the object to be coated, the auxiliary electrode is electrically charged to the same polarity as the gun so as to form an auxiliary electric field between the auxiliary electrode and the desired coating surface of the object to be coated whereby a powder coating material is transferred to be applied onto the desired coating surface by the electric field.
