<p>PURPOSE:To eliminate the uneven coating, and also, to secure the coating efficiency by coating with a metallic base paint by heightening discharge pressure of shaping air from a rotary atomization electrostatic coating machine, and lowering the pressure of the shaping air at the time of coating with a clear paint. CONSTITUTION:At the time of coating with a metallic base paint, pressure of shaping air discharged from a rotary atomization electrostatic coating machine M is set to high pressure for increasing the collision speed of metallic base coating grains onto an object W to be coated. Also, in order that a pitch in a reciprocating locus of the rotary atomization electrostatic coating machine M becomes a value set in advance, its reciprocating speed is controlled, based on the speed of the conveyor (b). Subsequently, at the time of coating with a clear paint, pressure of the shaping air is set to a value being lower than the value set at the time of coating with the metallic base paint. As a result, at the time of applying the rotary atomization electrostatic coating machine for metallic coating, uneven coating is not generated, and also, it contributes to resources saving and prevention of environmental pollution.</p> |
