Abstract
An injection molding method includes: a plasticizing process of feeding a resin pellet and additive components to a heating cylinder including a screw that can rotate around a rotation axis and can advance and retreat along the rotation axis, and generating molten resin by rotating the screw in a normal direction; and an injection process of injecting to a cavity the molten resin containing the additive components. In the plasticizing process, retreat operation of forcibly retreating the screw is performed at a predetermined velocity by a predetermined stroke or a predetermined time.
