Abstract:
1. A molding manufacturing method, comprising: preparing a co-extruded long molding body including a molding main body made of thermoplastic material and a decorative layer higher than the molding main body in hardness and melt temperature, so that the decorative layer is provided along a longitudinal direction of the molding main body on a surface thereof; setting the molding body in a fixed die such that a back surface side of said co-extruded long molding body which is opposite of said decorative layer faces said fixed die; heating and softening an end portion of the molding body while maintaining a condition in which the decorative layer is harder than the molding main body, by irradiating an infrared ray onto a back surface of the molding main body corresponding to the end portion of the molding body; and press forming the end portion of the molding body, while maintaining a condition in which the decorative layer is harder than the molding main body, by pressing a movable punch onto the fixed die while the end portion of the molding body is in a heated and softened state to bend the end portion of the molding body to obtain an end cover portion having a predetermined shape, wherein said press forming is performed in an oblique direction with respect to the longitudinal direction of the molding, so that the decorative layer of the end portion moves closer to the fixed die.
