PROBLEM TO BE SOLVED: To stably produce a high quality molding even when a biomass resin low in heat resistance, for example, is used as a base resin since a molding material can uniformly be kneaded in a cylinder even when the molding material containing at least a powdery material and a pelletized material out of a powdery material, a pelletized material, and a liquid material is supplied directly into the cylinder through the hopper of an injection molding machine to be injection-molded.SOLUTION: In an injection molding method in which the molding material containing at least the powdery material and the pelletized material out of a powdery material, a pelletized material, and a liquid material is supplied directly into the cylinder 14 of the injection molding machine 10 to be injection-molded, one-shot portion of injection of each material is supplied into the cylinder 14 by using different metering feeders 35C and 37C so that a supply time zone from the start of supply to the end of supply synchronizes by at least 60%, and the supply is finished in a metering time period in the metering process of an injection molding cycle. |
