In the conventional procedure, paint is atomised by a rotating bell with 35 to 55,000 revolutions per minute and adheres electrostatically to the body. The new method works without electrostatics, relying instead on jet application. The paint is applied using an orifice plate that enables high edge definition with a variable paint thickness of between 1 and 48 millimetres. This requires maximum precision from both the robot and application technology.
