Abstract
A memory assembly (800), comprising: a storage media (802) tangibly embodying executable commands configured to direct a molding-system controller (114) to send a command signal to the first accumulator-control valve (106) and the first actuator control valve (110), the command signal configured to request: (i) the first accumulator-control valve (106) to permit flow of hydraulic fluid from the first accumulator assembly (108) to the first actuator assembly (112), and (ii) the first actuator control valve (110) to permit flow of hydraulic fluid from the first pump assembly (104) to the first actuator assembly (112) for the case where the molding-system controller (114) determines that the first actuator assembly (112) requires the flow from both the first pump assembly (104) and the first accumulator assembly (108) during a portion of a molding cycle.
