Abstract
Described is a method of controlling the mold filling process of a plastics injection molding wherein, for the purposes of avoiding fluctuations in the mass of the moldings, due to material not being of a uniform quality, the change-over point between the filling phase and the back-pressure phase is shifted by a predetermined value in dependence on the injection work which is detected during the filling phase.
