  • Publication number: 20200171737
    Abstract: A method for forming and filling a container. The method includes: determining an effective fill area of an opening of the container through which fluid can pass while a stretch rod is seated within the opening; actuating a seal pin to open a nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage and through the opening to simultaneously form and fill the container; detecting a degree to which the nozzle passage is open; increasing fill velocity of the fluid to the nozzle as the nozzle passage is opened; setting fill velocity of the fluid to a maximum fill velocity when the nozzle passage is opened such that an area of the nozzle passage is at least equal to the effective fill area at the opening of the finish; and closing the seal pin after the container is formed and filled.

  • Patent number: 10518464
    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.

  • Patent number: 10479014
    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.

  • Publication number: 20180326649
    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.

  • Publication number: 20180319071
    Abstract: A hydraulic blow molding apparatus having a container forming station with a forming head coupled to a source of liquid blow medium. The container forming station further includes a mold configured to receive a preform and has interior surfaces that define the container shape. The container forming station injects a liquid end product into the preform and expands the preform to simultaneously form and fill a container with the liquid end product. Prior to the container being removed from the container forming station and while it is still full of the liquid end product, a seal is engaged with the container.

  • Publication number: 20180305064
    Abstract: A method of inspecting a blow molded container having a finish, a base, a body between the finish and base, and etching at the base. The method includes identifying where on the base the etching is located, designating the base as accurately blow molded if the etching is located at a predetermined location of the base, and designating the base as not accurately blow molded if the etching is not located at the predetermined location of the base.

  • Patent number: 10035293
    Abstract: An apparatus and method for forming a plastic container is provided. The method includes disposing a preform into a primary mold cavity and applying pressurized air to urge the preform to conform to the shape of the primary mold cavity to form a primary article. The primary article is then permitted to shrink to a predetermined volume. The method can further include exposing the primary article to an internal vacuum to facilitate shrinking to a predetermined volume. The method further includes disposing the primary article into a second mold cavity and applying pressurized air to urge the primary article to conform to the second mold cavity to form an intermediate article. Finally, at least a portion of the intermediate article is trimmed off to form a final container.

  • Patent number: 9987787
    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.
