Abstract: The present invention prevents internal cracks occurring when an impeller molded using a fiber reinforced resin is manufactured by injection molding. This method for manufacturing an impeller is provided with: an injection step of filling a cavity with a molten resin containing reinforced fibers, from a gate side into which the molten resin flows, toward an opposite-gate side opposite to the gate side; and a dwell step of applying required pressure to the filled molten resin. In the injection step and the dwell step, directional cooling is performed with a temperature gradient such that the temperature becomes lower from the gate side toward the opposite-gate side. According to this method for manufacturing the impeller, the opposite-gate side shrinks with a decrease in the temperature of the molten resin since the temperature of the opposite-gate side is lower.

Abstract: This molding method involves: a first step in which a perforation pin (2) is made to protrude into a cavity (13) in a mold (1); a second step in which a molten resin (16) is injected to fill the cavity (13) so as to envelop the protruding part of the perforation pin (2); a third step in which, in a state in which the resin (16) is in an uncured state, the perforation pin (2) is made to protrude further; and a fourth step in which the resin (16) is cured to obtain a molded resin article.

Abstract: In the present invention, it is possible to reduce the occurrence of a local deformation in a plate material during solidification and shrinkage of an injection molding material. The composite material injection molding method includes an injection step of injecting an injection molding material containing reinforcing fibers onto one surface of a plate material; and a molding step of solidifying the injection molding material to mold a frame part so as to surround the outer periphery of the plate material and to mold a rib so as to define an inner peripheral-side space on the inner peripheral side of the frame part. In the injection step, the injection molding material is injected so that a weld part at which the injection molding material converges is formed in a region not overlapping the plate material of the frame part.
