摘要：Provided is an injection molding method for a resin material with which a stablereinforcing fiber content can be obtained. This injection molding method, which isprovided with a heating cylinder (201) on the front end of which a discharge nozzle (203)is formed, a single axis screw (10) provided so as to be rotatable inside the heatingcylinder (201), and a fiber-supplying device (213) for filling reinforcing fiber (F) into theheating cylinder (201), and which performs injection molding while supplying thereinforcing fiber (F) and the resin starting material separately and supplying thereinforcing fiber (F) on the front side of the resin starting material. The method ischaracterized in that: the method is provided with a plasticization process for obtaining aspecified amount of a kneaded product by retracting the screw (10) while rotating in thenormal direction to melt the resin starting material and knead reinforcing fiber (F) intothe melted resin starting material, and an injection process for discharging the kneadedproduct from the discharge nozzle (203) by advancing the screw (10); and reinforcingfiber (F) is supplied into the heating cylinder (201) in the injection process.
