ABSTRACT:
A molding having an attractive end portion or other portion with a formed contour is provided by the steps of providing an extruded elongated molding. Thereafter a portion of the molding is removed for forming a cavity. A second core material is injection molded into the cavity while reshaping the molding to a desired shape. A molding of the present invention has a first core with a relatively thin skin extruded thereover and a second core material in a reshaped portion of the molding. Alternatively, a molding can be made from a solid extrusion with a replacement of a core of the solid extrusion at a portion of the molding to be reformed.
