AUTOMOTIVE TRIM PIECE

摘要

A molding for installation on a vehicle which includes a decorative injection-molded polymeric skin secured to an outwardly facing portion of an elongate core and method of manufacture thereof. The skin extends along the length of the molding and includes a cap unitarily formed therewith at each end of the molding. Each cap is shaped to conceal the core when the molding is installed on the vehicle. The skin of the molding may be secured to the core by a heat activable adhesive. Alternatively, the molding includes an extruded first polymeric layer compatible with the polymeric skin between a first area of the outwardly facing portion of the core and the skin, the skin being directly bonded to the extruded polymeric layer and the extruded polymeric layer being adhesively bonded to the core. In illustrated embodiments, the extruded polymeric layer and the polymeric skin are each of polyvinyl chloride, but the extruded polymeric layer and the polymeric skin may together be selected from the group of: thermoplastics including polypropylene, modified polypropylene; and thermoplastic elastomeric materials. The injection-molded skin and end caps of the molding are generally seamless, but the skin may present areas of varying gloss and/or texture. The molding may include a second polymeric layer secured directly to a second area of the core, which second polymeric layer may be selected from the group of: ethylene propylene diene monomer and thermoplastic elastomeric materials. The molding may be tapered from one of its ends to the other or it may be of constant cross-section along its length.
