ABSTRACT:
In an injection molding apparatus using a motor as a driving source, the injection speed and the injection pressure are controlled via a speed sensor, a pressure sensor and a closed loop control system, to provide higher accuracy and better operability during switching of the apparatus from an injection speed control phase to an injection pressure control phase and thereafter to a back pressure control phase.
