METHOD OF MANUFACTURING INTEGRATED CHANGABLE INSERT MOLDINGS FOR AUTOMOBILES

摘要

A method of manufacturing an integrated changeable insert molding attached to a car body at a position above the door of an automobile. The method includes press blanking a stainless coil (10) into a predetermined shape; forming locking edges (11) along the opposite edges of the coil; and seating the coil (10) in a mold and injecting a melted synthetic resin into the mold, thus forming a molding body (20) to be integrated with the stainless coil through an insert-injection molding process, in which the locking edges are embedded in the molding body (20) and a plurality of locking bosses (30) made of a material identical to the material of the molding body is formed to be integrated with the molding body and is separated by predetermined intervals. Thus, only one insert-injection molding process is executed during the method, thus simplifying the process of manufacturing the moldings compared to conventional methods.
