Abstract: A control method for an injection molding machine including a measurement process of measuring molten resin by moving a screw backward while rotating the screw in a heating barrel for melting a resin material, a rotational speed of the screw is reduced from a timing when a backward movement speed of the screw is reduced at the measurement process before the measurement process is completed, for stopping backward movement of the screw when the measurement process is completed, and the rotational speed and a rotation direction of the screw are controlled such that a back pressure as a pressure of the molten resin measured at the measurement process becomes a target pressure lower than the back pressure of when the measurement process is completed, when a target time comes.
