Abstract

See full text

The resin injection molding method of the present invention is a method for molding resins inside a cavity formed within a mold. The method comprises injecting resins into the cavity through a plurality of paths installed so as to be openable and closable and optionally maintaining the resin inside the cavity at a pressure; closing each of the plurality of paths such that the resins injected from each path converge, there being a time difference between when a first path and a second path of the plurality of paths are closed; and solidifying at least the resin which is injected from the path closed earliest with a crystallinity greater than or equal to a predetermined crystallinity degree.
