Injection molding method and injection molding machine

An injection molding machine comprising:

• a cylinder that is provided with a discharge nozzle on the front side;
• a screw that is provided inside the cylinder so as to be able to rotate normally and reversely around a rotating axis;
• and
• a control section that controls an operation of the screw,
• wherein plasticizing is performed by applying a shearing force to a resin raw material and an added component which are supplied to the cylinder, through a normal rotation operation of the screw, and a molten resin is generated, and
• wherein the control section is able to control a reverse rotation of the screw and is able to be set a condition of a reverse rotation operation of the screw with an arbitrary value, in the plasticizing.

• wherein the control section is a control device which is able to control alternate switching of the screw between the normal rotation and a rotation halt and is able to set a condition of halting the screw with an arbitrary value, in the plasticizing.
