Abstract
A resin panel of which contact surfaces of a rear wall to be in contact with another member are made unlikely to deform while reducing the weight of the resin panel. The panel includes a rear wall having a plurality of contact surfaces to be in contact with another member, and a front wall opposing the rear wall with an interval therebetween, the resin panel including a plurality of ribs obtained by indenting parts of the rear wall toward the front wall and welding the parts to an inner surface of the front wall, wherein a wall thickness of the front wall is generally equal to or smaller than a wall thickness of the rear wall.
Claims6
A molding method for molding a resin panel, the resin panel being formed by sandwiching a reinforcement between a pair of molten resin sheets, the method comprising:
- an extrusion step of extruding the molten resin sheets;
- a shaping step of shaping one of the molten resin sheets into a shape conforming to a cavity of one of a pair of molds;
- an attaching step of pressing the reinforcement against the one of the molten resin sheets so as to attach the reinforcement to the one of the molten resin sheets;
- and
- after the attaching step, a clamping step of clamping the molds together having the reinforcement between the molds so as to weld together edges of the molten resin sheets, thereby molding the resin panel,
- wherein in the attaching step, the reinforcement is a beam shape, and the reinforcement is attached to the one of the molten resin sheets in a predetermined angle from the cavity of one of the pair of molds;
- in the attaching step, only the reinforcement is held by a manipulator and pressed against the one of the molten resin sheets by the manipulator;
- the manipulator comprises a suction pad;
- and
- the suction pad suctions the reinforcement so that the suction pad is in contact with the reinforcement so as to hold the reinforcement.
