The first report confirmed the design of the adaptive injection and dwelling controller in a simulation model, the robustness for parameter change and the possibilities for application. This paper describes the next step: application to an actual commercial real injection molding machine. We examine hybrid control as well as process control of injection and of the dwelling processes. To clarify the designed strategy performance, we compare the proposed method and a PI controller in a sequence of production processes. The cold start operation, i.e., operating the machine without warm-up routine also examined for actual application. The evaluation of product thickness shows how effective the proposed controller will be in an actual machine.
