Electrostatic coating method

摘要

A workpiece (2) is electrostatically coated by a rotary atomizing electrostatic coating apparatus (1). Electrically conductive paint is supplied to the coating apparatus (1), and a voltage applied to the apparatus is controlled in dependence upon an area of workpiece to be coated, thereby to vary a coated pattern width on the workpiece. This method is particularly useful in the coating of automobile bodies allowing narrow areas, such as pillars, to be more evenly coated.
