摘要
Disclosed is a method of injection-molding for epoxy resin moldings wherein an 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 be minimized as well as an injection-moldable epoxy resin composition excellent in thermal stability possessing latent-type curing characteristics capable of rapidly promoting curing reaction in a metal mold without being cured in an injection molding machine.;The aforesaid method is carried out by charging an epoxy resin composition possessing the latent-type curing characteristics into a mini-sprue metal mold which is composed of a manifold part, a mini-sprue part and an ejector-plate part and wherein a metal mold temperature at the manifold part is so maintained that the epoxy resin composition is molten but curing of the composition is not promoted, and injection-molding the composition.
