  • Patent number: 7643900
    Abstract: Embodiments of the present invention teach a method of controlling a screw in a two-stage injection unit and a system for implementing the method. For example, a method of controlling a screw in a two-stage injection unit, the method executable at a computing apparatus associated with the two-stage injection unit is disclosed. The method comprises receiving an indication of an operational parameter associated with the screw of the two-stage injection unit; based on the indication of the operational parameter, determining a target speed (STARGET) for the screw, the target speed (STARGET) being sufficient to enable the screw to produce a required amount of material in a molten state; causing the screw to rotate at the target speed (STARGET), thereby causing the screw to operate in a substantially continuous manner.
