ABSTRACT:
There is disclosed a method for controlling a fill speed of an injection unit, the method executable in a computing apparatus configured to control a plunger actuator of the injection unit. The method comprises receiving an indication of a mold-cavity-filling parameter, the mold-cavity-filling parameter being indicative of a number of molding cavities of a multi-cavity mold having been filled; responsive to the mold-cavity-filling parameter satisfying a pre-determined threshold, releasing a control signal to the plunger actuator to control speed associated with a plunger of the injection unit from a first filling speed to a second filling speed.
