NOVELTY - A molding-system controller (114) comprises device for permitting flow of hydraulic fluid from: (i) first accumulator assembly (108) to first actuator assembly (112), and (ii) first pump assembly (104) to first actuator assembly, for a case where the molding-system controller determines that first actuator assembly requires the flow from both first pump assembly and first accumulator assembly during a portion of molding cycle.    USE - As molding-system controller (claimed), used for controlling operation of hydraulic circuits.    ADVANTAGE - The pump and accumulator provides the hydraulic fluid to the first actuator assembly during a portion of molding cycle of the molding system is a reduction, at least in part, in energy consumption since the pump can be sized somewhat smaller since the first accumulator assembly can be relied upon for supplementary hydraulic fluid, from time to time, as may be required. By using the molding-system controller, the first accumulator assembly can be filled to an optimum pressure level depending on the molding cycle of the molding system. Filling the first accumulator assembly to an optimum level with hydraulic fluid may further improve energy efficiency because less energy in the pressurized hydraulic is converted to heat in order to limit the motion of the first actuator assembly.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) memory assembly comprising storage media tangibly embodying executable commands configured to direct a molding-system controller to send a command signal to a first accumulator-control valve and to a first actuator control valve, where command signal configured to request: the first accumulator-control valve to permit flow of hydraulic fluid from a first accumulator assembly to first actuator assembly, and the first actuator control valve to permit flow of hydraulic fluid from a first pump assembly to the first actuator assembly for a case where molding-system controller determines that first actuator assembly requires the flow from both the first pump assembly and the first accumulator assembly during a portion of a molding cycle;    (2) molding system comprising first hydraulic circuit, including reservoir, first pump assembly, first accumulator-control valve, first accumulator assembly, first actuator control valve, first actuator assembly, and molding-system controller; and    (3) method of operating a molding-system controller, involving configuring the molding-system controller to send a command signal to a first accumulator-control valve and a first actuator control valve    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of first hydraulic circuit.
