Abstract
A system and method for controlling the injection of material through two or more gates into the cavity of injection-molding apparatus. In this system, a sensor develops an indication of unbalanced flow conditions produced by the injection of the material into the cavity of the mold. A regulator also forms part of the system and serves to adjust the relative amounts of material passing through the gates. The method includes sensing unbalanced flow conditions produced by the material injected into the cavity and adjusting the relative amounts of materials injected into the cavity through the various gates.
