ABSTRACT:
In an injection machine of the type wherein plastic material is injected into a pair of separable mold halves by means of an injection plunger actuated by pressurized fluid, a comparator is provided to compare a signal representing the actual spacing between the mold halves and a reference signal corresponding to a predetermined permissible value of the spacing at a predetermined position of the injection plunger. The output of the comparator is used to change the pattern of the force of the pressurized fluid acting upon the injection plunger during the next molding cycles.
