ABSTRACT:
A controller for an injection molding machine controls the injection ram by means of profiles having segments with programmable setpoints and boundary points. A profile associated with a particular stage of the injection molding cycle may be assigned one of several control functions having dependent variables of velocity or pressure and independent variables of time or ram position. The particular control function may be changed between injection stages. The programmable setpoints permit accurate representation of complex profiles with a limited number of segments.
