Title:
INJECTION MOLDING METHOD AND INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/084271
Kind Code:
A1
Abstract:
Provided is an injection molding method for resin that contains reinforcing fiber, the method being capable of easily eliminating uneven distribution of added components. The injection molding method is provided with: a plasticizing step for supplying resin pellets P and added components to a cylinder equipped with a screw 10, which has a rotating axis as the center and is capable of rotating normally and in reverse, and generating molten resin by rotating the screw 10 in the normal direction; and an injection step for injecting the molten resin M comprising the added components into a cavity. In the plasticizing step, a reverse rotation operation for reversing the rotation of the screw 10 is performed or a screw-stopping operation of stopping the normal rotation of the screw 10 is performed with a prescribed timing and for a prescribed period.
