PROBLEM TO BE SOLVED: To provide a method for manufacturing an injection molding capable of inhibiting the generation of a weld line.SOLUTION: The provided method for manufacturing an injection molding entails, on an occasion for injecting and filling a molten resin 10 into a cavity 1, the aggregation of the molten resin 10. A reservoir unit 5 is configured consecutively to the aggregation unit 7 of the cavity 1 where the aggregation of the molten resin 10 arises so as to release a gas compressed within the latter. The gas within the cavity 1 is streamed into this reservoir unit 5 so as to inject the molten resin 10 into the cavity 1. |
