Abstract

A method of manufacturing the molding 1 comprising a forming process of preparing a molded material 100 which is used as a core metal 10 and has a uniform sectional configuration by forming a material of the core metal 10 into a predetermined configuration; a cut-off process of cutting off a part of the molded material 100 to prepare the core metal 10 whose sectional configuration is varied; and an extrusion process of variably extruding the synthetic resin 19 onto a surface of the core metal 10 by moving a movable die 41 according to the sectional configuration of the core metal 10, using an extruding die body 40 and the movable die 41 installed on the die body 40. According to this method, the adherence of the synthetic resin to the core metal can be reliably accomplished, and thus the molding-manufacturing method having a high productivity can be provided.
