METHOD FOR MOLDING EPOXY RESIN MOLDING BY HIGH SPEED INJECTION-FILLING

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an epoxy resin molding in which a filling time can be shortened, a mold closing time (an injection time + a curing time) is shortened, and a molding cycle is shortened approximately to that of a thermoplastic resin.;SOLUTION: In the method for molding the epoxy resin molding, when an epoxy resin composition is supplied to mold the molding, the composition is supplied at a speed of at least 3.5 cc/s. The composition having latent curing characteristics in which the gelation time of the composition at 100°C is at least 1,000 s, and the activation energy of the composition is at least 12,000 cal/mol is used.;COPYRIGHT: (C)2002,JPO
