In apparatus for controlling a plasticizing process of a resin of an in-line screw-type injection molding machine, a position of the screw is continuously detected in accordance with the movement thereof and a control function is determined on the basis of one of various factors, such as resin heating energy, shearing energy, injection pressure and filling speed, which determine a temperature distribution of a resin to be injected. The operating condition, particularly the number of revolutions and the back pressure of the screw, is controlled on the basis of the control function and the screw position so as to uniformalize the temperature distribution of the resin.
