PURPOSE:To manufacture the molded form of high quality by a method wherein the temperature change of a specified place in a screw for an injection molding machine is measured and a proportional flow amount valve is operated by the value of the measurement to regulate the revolving number of said screw and keep the temperature of molten resin in
constant at all times. CONSTITUTION:In order to control the temperature of molten resin upon plasticization, a plurality of thermocouples 21, embedded along the groove of a screw, detect the temperature of the molten resin. A difference between the detected temperature of the resin and a preset value is calculated and the value of the operation is inputted into a
plasticization controller 29. A proportional flow amount valve 8 is operated by the commands A, B of the plasticization
controller 29 to regulate a hydraulic motor 4 and keep the temperature of the molten
