Abstract
A method of powder coating a workpiece in a housing having a powder coating area with a workpiece travel path and an interior wall surface sloped around at least a portion of the workpiece travel path includes moving air and powder in the powder coating area along at least a portion of the sloped interior wall surface. As a result, a swirling flow pattern of the air and powder is produced around at least a portion of the workpiece travel path. The workpiece is conveyed along the workpiece travel path, and powder is deposited from the swirling flow pattern onto the workpiece along the portion of the workpiece travel path around which the interior wall slopes.
