Abstract: Apparatus and method for performing an injection molding cycle in an injection molding apparatus where the apparatus comprises: a manifold, an actuator associated with a respective gate, each gate having a downstream sensor generating a response signal upon sensing a selected condition of the injection fluid material, each gate having an upstream sensor generating a response signal upon sensing the selected condition of the injection fluid material, the upstream and downstream sensors sending response signals to a controller on performance of each successive injection cycle by the apparatus, the controller comparing a standard amount of elapsed time with a calculated amount of elapsed time and adjusting the velocity or position of each of the actuators such that the amount of time elapsed approaches or matches the standard amount of elapsed time.
