METHOD FOR MANUFACTURING INJECTION-MOLDED OBJECT HAVING THIN-WALLED PART

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an injection-molded object having a thin-walled part, capable of simply molding a molded article having a magnetic shielding function. SOLUTION: A resin film 6a and a shielding film 6b to which magnetic shielding treatment is applied are integrated to constitute a laminated film 6 becoming the thin-walled part 4 of the molded object 1. The laminated film 6 is incorporated in the cavity 13 formed by a movable mold 12 and a fixed mold 11 and a molten resin is injected in the cavity 13. At this time, the resin film 6a is melted by the heat of the molten resin to be integrally bonded to the molded object 1. By this constitution, the thin-walled part 4 of the molded object 1 is formed from the laminated film 6 and the magnetic shielding function is imparted to the molded object 1 by the shielding film 6b.
