Metallic workpiece powder coating method for use in coating plant, involves cleaning surface of workpiece by particles that are thermally released in treatment section, and heating workpiece only near-surface of workpiece by eddy current
The method involves heating near-surface region of a workpiece by eddy currents produced by induction. The surface of the workpiece is cleaned by particles that are thermally released in a treatment section. The coating powder is applied on the workpiece, where the near-surface region is brought into a temperature level. The workpiece is heated only near-surface of the workpiece by eddy current and is held in the temperature level. The coated workpiece is passed through a cooling phase by a cooling section (5). An independent claim is also included for an arrangement for implementing a method for electrostatic powder coating of metallic workpiece and curing of the powder coating.
