Abstract
A method and system for hydraulic blow molding a container from a preform. A molding medium is injected into the preform from a nozzleduring 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. 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.
