摘要： A plasticizing screw for injection molding according to the present invention is a plasticizing screw for injection molding that is installed in an injection molding machine which performs injection molding by plasticizing granular thermoplastic resin feedstock containing reinforcement fibers, and includes a shaft, a flight, and a mixer. The mixer is provided in plural stages in an axial direction, and the number of fins of the mixer of each stage increases toward a leading end side in the axial direction from a rear end side in the axial direction. Further, the protrusion height of each fin from the peripheral surface of the shaft is lower than the protrusion height of the flight from the peripheral surface of the shaft.

摘要： A plasticizing screw for injection molding according to the present invention is installed in an injection molding machine that performs injection molding by plasticizing thermoplastic resin feedstock containing reinforcement fibers, and includes a shaft, a main flight, and a sub-flight. The protrusion height of the main flight from the circumferential surface of the shaft is formed to be constant in at least an area in which the sub-flight is provided. The sub-flight includes a flat surface portion which is provided on the rear end side in a winding direction and in which a protrusion height from the circumferential surface of the shaft is lower than that of the main flight and is constant, and an inclined surface portion which is provided to extend continuously from a leading end in the winding direction of the flat surface portion and in which a protrusion height from the circumferential surface of the shaft gradually increases toward the leading end side in the winding direction and is less than the protrusion height of the main flight.
