A METHOD OF CONTROLLING A SCREW IN A TWO-STAGE INJECTION UNIT AND A SYSTEM FOR IMPLEMENTING THE METHOD

摘要

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 (106) in a two-stage injection unit (100), the method executable at a computing apparatus (140) associated with the two-stage injection unit (100) is disclosed. The method comprises receiving an indication of an operational parameter associated with the screw (106) of the two-stage injection unit (100); based on the indication of the operational parameter, determining a target speed (S TARGET) for the screw (106), the target speed (S TARGET) being sufficient to enable the screw (106) to produce a required amount of material (112) in a molten state; causing the screw (106) to rotate at the target speed (S TARGET), thereby causing the screw (106) to operate in a substantially continuous manner.
