INJECTION-MOLDING METHOD, INJECTION-MOLDING MACHINE, AND MEDIUM-FEEDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an injection-molding method and an injection-molding machine which can quickly raise the surface temperature of a die by directly heating the surface of the die, and to provide a medium-feeding device which feeds a medium to the injection-molding machine.;SOLUTION: A heated medium is fed into a cavity 62 which is formed in a die device 23, and the surface of the cavity 62 is raised up to a high temperature. A resin molded article is molded by injecting a molten resin into the cavity 62, and the medium is discharged from the cavity 62. The medium may be fed into the cavity 62 during a die closing process of the die, and also, the discharge of the medium may be completed before the molten resin comes into contact with the medium.;COPYRIGHT: (C)2007,JPO&INPIT
