ABSTRACT:
Relatively small parts are powder coated without fixturing by placing the parts on a heat conductive surface and the powders are distributed over the exposed surfaces of the parts. The powders on the surfaces of the parts are heated to fuse the powders, as by radiant heat, while the heat conductive surface is kept at a temperature below that at which overspray powders on the conductive surface will become tacky. In a preferred embodiment, the heat conductive surface is an endless belt which advances the parts past a powder coating station, past a top heating-bottom cooling station and then to discharge.
