Abstract: A method and molding system for hydraulic blow molding of a container from a preform. The method precharges the molding medium within a fill head unit to a precharge pressure. During the injecting of the molding medium into the preform, the method further increases the pressure of the molding medium to a pressure greater than the precharge pressure.

Abstract: A method and system for hydraulic blow molding a container from a preform 24. A molding medium is injected into the preform from a nozzle 12 during a first molding stage. In the first molding stage, the molding medium is injected so as to be specifically directed at a closed end of the preform 24. During the first molding stage, the preform is axially stretched in response to the force exerted on the preform by the molding medium. The molding medium is also injected into the preform during a second molding stage, where the molding medium is injected at a flow rate greater than a flow rate during the first molding stage. During the second molding stage, the preform is radially expanded into the shape of the container.
