    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 method of hydraulically blow molding a container from a preform using a liquid end product as a liquid blow medium. The method includes the steps of hydraulically blow molding a formed and filled container from a preform using the liquid blow medium and engaging a fluid tight seal with the container while the container is retained within a mold in the forming station. The engaging of the seal includes engaging an axially extending ring of the seal in one of a press-fit or frictional engagement with an inner surface of the container such that the seal is retained on the container by that engagement.

    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 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.

    Abstract translation: 一种用于从预制件24液压吹塑容器的方法和系统。在第一模塑阶段期间，将模制介质从喷嘴12注入到预成型件中。 在第一成型阶段，注射成型介质以特别地指向预成型件24的封闭端。在第一成型阶段期间，预成型件响应于通过模制介质施加在预制件上的力而被轴向拉伸 。 在第二模塑阶段期间，模塑介质也被注入到预成型件中，其中模塑介质以大于第一模塑阶段的流速的流速注入。 在第二成型阶段期间，预成型件径向膨胀成容器的形状。
