INJECTION MOLDING, CONTINUOUS MOLDING METHOD OF HIGH FREQUENCY WELDER AND MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a molding method capable of injecting and joining a plurality of molded products which are molded by injection-molding a material even if the material used in injection molding is a soft material or a material high in dielectric loss factor, for example, a vinyl chloride resin or a polyamide resin, using one mold not to increase or change the size of the shape of the joining part of a primarily molded product in the molding method and to reduce the cost of the molding method as compared with a conventional method while suppressing irregularity.;SOLUTION: In the molding method of the molded product made of a synthetic resin constituted by joining a plurality of parts, the joining of a plurality of the parts is performed using the same mold as the mold 1 used for molding a plurality of the parts and the joining parts of a plurality of the parts are joined by high frequency welding so that the injection molding and the high frequency welding are performed as the continuous operation of a molding machine.;COPYRIGHT: (C)2006,JPO&NCIPI
