摘要： Method for making a thermoplastic resin handle for vehicle door and the resultant handle. The handle includes a handle body of the thermoplastic resin and a sheet metal covering the body. The metal sheet is secured to the face of the handle body by means of a plurality of projections in the back face of the sheet metal. Each projection is embedded in the layer of the resin of the handle body throughout its entire length to provide a better grip thereby. In the steps for embedding the projection in the resin body, supersonic waves are applied to the sheet metal to cause frictional vibrational movement relative to the handle body and to, in turn, cause heat sufficient to melt a zone of the body necessary to plunge each projection into the handle body.
