ABSTRACT:
An apparatus and method of applying a lubricating material to an outer surface of a workpiece. Initially, a workpiece is provided that is preferably formed from a closed channel structural member having a circular or box-shaped cross sectional shape. Lubricating material is applied to an outer surface of the workpiece. In a second step of the method, the workpiece may be heat treated. The workpiece is then heated to elevate the temperature of the workpiece so as to cause the lubricating material to dry substantially immediately on the workpiece, thereby providing a coating of lubricating material having a substantially uniform thickness. In a fourth step of the method, a deforming process is performed on the workpiece during the period of time following the heat treatment process, and after applying the lubricating material, in which the workpiece retains the full or partial softening characteristics.
