Abstract (en)
[origin: WO2015078567A1] The invention relates to a method for producing a large-surface exterior trim panel for a movable body part of a motor vehicle, in particular a door, front hood, or tailgate of a passenger car, in which at least one large-surface sheet metal part forming the exterior trim panel is shaped into a three-dimensional form by means of a forming tool. To at least part of the inner side of the shaped sheet metal part (1), a reinforcement (2.2, 2.3) made of plastic is applied by way of back injection molding, wherein as a sheet metal part, a sheet metal part having a sheet thickness of less than 0.6 mm, preferably less than 0.5 mm is used. By way of seam-folding and/or adhesive bonding, the shaped sheet metal part (1) having the at least one reinforcement is connected to an inner structure (6) made of sheet metal and/or plastic. By means of the method according to the invention, such an exterior trim panel can be produced as a high-quality exterior trim panel that is relatively lightweight, yet has sufficient stiffness against denting, in a cost-effective way. The invention further relates to a corresponding external trim panel.
