    摘要： In one aspect, there is provided an injection molding system configured to operate in a plurality of cycles. The system comprises, amongst other things, a controller that is configured for performing a comparison of a variable pressure setpoint with a target pressure value. The controller is configured to, when the target pressure value is less than the variable pressure setpoint by at least a predetermined lower bound, (i) decrease the variable pressure setpoint to a reduced variable pressure setpoint and (ii) not further decrease the variable pressure setpoint from the reduced variable pressure setpoint until the pump assembly operates for a plurality of stabilizing cycles at the reduced variable pressure setpoint.

    摘要： An injection molding press (1) for molding preforms, which comprises a supporting footing (2) for a molding device (3) which comprises a fixed mold part (4) and a movable mold part (5), the movable mold part (5) being supported so that it can slide along a movement direction (100) with respect to the footing (2) in order to pass on command between a condition in which it is close to the fixed mold part (4), in which it cooperates with the fixed mold part (4) to define the injection cavities of the preforms and in which the molding device (3) is in the closed condition, and a spaced-apart condition, in which the molding device (3) is in the open condition, the movable mold part being associated with an extraction plate (6) configured to perform the extraction of the preforms from the mold parts (4, 5) with the molding device in the open condition, a hydraulic actuation circuit (10) being provided which is configured to actuate at least one actuator associated with the extraction plate and/or the movable mold part (5); the movable mold part (5) comprises a plurality of plungers which define respective male elements which cooperate with respective female elements supported by the fixed mold part (4) in order to define respective molding cavities of the preforms, the plunger elements being associated with means for movement on command for their movement, when the molding device (3) is in the closed condition, along a direction that is substantially parallel to the movement direction (100) of the movable mold part (5), the means for movement on command of the plungers comprising a hydraulic actuation unit (11) connected to the hydraulic actuation circuit (10).

    摘要： 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.
