Abstract: A method for controlling the temperature, for example in an injector of a thermoplastics injection system which uses a closed-loop servocontrol system in which the electrical heating resistor (R) is periodically deactivated for short periods of time (Vc, Vr) in order to extrapolate the actual temperature (Tpl) of the plastics (P) in the injector, in order to control it as accurately as possible and to reset the parameters of the closed-loop servocontrol system.
