Abstract: There is provided a screw of an injection molding machine that can eliminate uneven distribution of additive components without giving an excessive shear force to the additive components. An injection molding method of the present invention includes: a plasticizing process of feeding a resin pellet P and additive components to a heating cylinder 201 including a screw 10 that can rotate around a rotation axis C and can advance and retreat along the rotation axis C, and generating molten resin M by rotating the screw 10 in a normal direction; and an injection process of injecting to a cavity the molten resin M containing the additive components. In the plasticizing process, retreat operation of forcibly retreating the screw 10 is performed at a predetermined velocity by a predetermined stroke D1 or a predetermined time.

Abstract: In an injection molding method of fiber reinforced resin of the present invention, a resin accumulation region is provided closer to a downstream side than an injection completion position inside a heating cylinder, an injection pressure is given to molten resin that occupies the resin accumulation region in an injection process of a preceding cycle, and a shear force is given to the molten resin that occupies the resin accumulation region in a plasticizing process of a subsequent cycle. An inside of massive reinforcing fibers F is impregnated with the molten resin by giving a high injection pressure to the molten resin that occupies the resin accumulation region. Next, dispersion of the reinforcing fibers is promoted by giving a shear force in the plasticizing process of the subsequent cycle.

Abstract: There is provided a screw of an injection molding machine that can eliminate uneven distribution of reinforcing fibers without giving an excessive shear force to the reinforcing fibers. A screw is provided inside a heating cylinder of an injection molding machine to which a resin pellet is fed on an upstream side in a conveyance direction of resin and to which reinforcing fibers are fed on a downstream side therein, and includes: a first stage at which the resin pellet which is fed is melted; and a second stage that continues to the first stage, and at which molten resin and the reinforcing fibers are mixed with each other. A second flight provided at the second stage includes: a large-diameter flight with a relatively large outer diameter; and a small-diameter flight with a relatively small outer diameter.
