Integrated changeable insert molding for an automobile and manufacturing method thereof

An integrated changeable molding which is attached to a portion of a vehicle frame above a door of an automobile, the integrated molding comprising:

• an elongated arcuate stainless coil having a width which varies from a first end to a second end of said coil, having a first surface to which adhesive is applied and a second surface to which a protective tape is attached, the stainless coil being pressed into an integrated coil body having a desired shape corresponding to the integrated molding through blanking by a press, both ends of the integrated coil body being slightly bent through press forming;
• a polypropylene resin body integrally formed on an inner surface of the stainless coil through a first insert injection molding, the propylene resin body including a propylene resin layer and a plurality of clips formed integrally with the propylene resin layer;
• and
• polypropylene resin caps integrally formed on both side edges of the integrally-attached stainless coil and first polypropylene resin layer through a second insert injection molding, each of the polypropylene resin caps having a second polypropylene resin layer, the stainless coil and the first and second polypropylene resin layers formed integrally with each other being subjected to a finishing process, thereby producing the integrated molding.
