摘要
Disclosed is a method of injection-molding for epoxy resin moldings whereinan epoxy resin composition is used as starting material, a molding cycle is shortened,a continuous molding operation is possible and a waste portion after curing can beminimized as well as an injection-moldable epoxy resin composition excellent inthermal stability possessing latent-type curing characteristics capable of rapidlypromoting curing reaction in a metal mold without being cured in an injection moldingmachine.The aforesaid method is carried out by charging an epoxy resin compositionpossessing the latent-type curing characteristics into a mini-sprue metal mold whichis composed of a manifold part, a mini-sprue part and an ejector-plate part andwherein a metal mold temperature at the manifold part is so maintained that the epoxyresin composition is molten but curing of the composition is not promoted, andinjection-molding the composition.
