INJECTION MOLDING METHOD FOR RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an injection molding die and a resin molding method which make it possible to stably mold an inexpensive molded object whose silver streak is suppressed and weldline is eliminated.SOLUTION: A method for subjecting a resin composition to injection molding uses an injection molding die 1 including a mold cavity 4 for molding, a runner that introduces the resin composition loaded from a sprue 5 into the mold cavity 4, and a gate that connects the mold cavity and the runner. Shear heating of the gate part is 30°C or below. A predetermined polycarbonate resin composition is used as the resin composition.
