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.

摘要： There is provided a mold clamping apparatus that can prevent a molding material from spouting from a split surface of a mold even if in-cavity resin pressure causes offset of a mold opening force, and can extend the life of the mold. The mold clamping apparatus includes a control device that estimates a mold opening force by mold internal pressure for molding with mold internal pressure being asymmetrical with respect to a center of a mold block, determines a mold clamping hydraulic value applied to each tie bar correspondingly to the estimated mold opening force, and distributes hydraulic pressure supplied to each tie bar so that the determined mold clamping hydraulic value is reached.

摘要： A method for manufacturing a fiber-reinforced composite material of the present invention includes: the step (a) of placing a non-woven fabric N made of a reinforcement fiber in a movable mold 12; and the step (b) of moving the movable mold 12 toward a fixed mold 11 to close the mold and then injecting a thermoplastic resin into the mold to obtain a molded article formed of the non-woven fabric N and the thermoplastic resin. The mechanical strength of the obtained fiber-reinforced composite material can be enhanced by applying an injection compression molding process as the injection molding process in the step (b).
