    Abstract: A molding system for hydraulic blow molding of a container from a preform. The molding includes a pressurization unit that is configured to receive liquid molding medium from a source; a fill head unit coupled to the pressurization unit to receive the liquid molding medium therefrom; a mold assembly defining a mold cavity in the shape of the container. During forming of the container, a nozzle piston is moved from a retracted position to an extending position where the nozzle piston is engaged to inject the molding medium into the preform, thereby forming and filling the container. The fill head unit defines a receiving chamber for the liquid molding medium that maintains a constant volume during movement of the nozzle piston between the retracted and extended positions.

    Abstract: A hydraulic blow molding system for forming a container from a preform by injecting a liquid product into the preform. The system includes a seal pin located within the forming head and moveable between a closed position and an opened position. In the closed position a sealing portion of the seal pin is in sealing engagement with a portion of the forming head so that an exit orifice is closed and liquid product is prevented from being injected into the preform. In the opened position, the sealing portion is disengaged from the portion of the injection head so that the exit orifice is open and the liquid product can be injected into the preform.

    Abstract: A blow molding system having a blow molding station with at least one mold assembly and method for forming a filled container therewith. The blow molding station including at least one blow nozzle coupled to a source of blowing medium and configured to discharge the blowing medium into the preform to simultaneously form and fill a container with the blowing medium, wherein the blowing medium is the product to be contained within the container. A blow-off nozzle is provided and oriented in a direction to discharge a stream of cleaning medium at the blow nozzle causing residual blowing medium to be removed from the blow nozzle.
