Abstract: A method for forming a plastic container in which a heated end product is introduced into a heated preform to expand the preform into at least partial conform with the cavity surfaces of a mold, thereby forming a resultant container, of a first size, with a heated end product. The resultant container is then capped and shrunk to a second size, which is less than the first size. The shrinkage of the reluctant container is greater than the shrinkage of the end product thereby creating a positive pressure within the capped container.

Abstract: A method of forming a plastic container from a preform that includes cooling and optionally providing counter pressure to a finish of a preform during forming of a container. During the method, an injection nozzle directs a cooling medium into a receiving space into which the finish is received.

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: 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 nozzle and system for hydraulic blow molding of a plastic container from a preform. The nozzle includes a nozzle body having a main bore extending therethrough and a seal pin received in the main bore and moveable between a closed position and an opened position. The seal pin include a central bore extending from an entrance orifice to an exit orifice, with the entrance orifice opening into the main bore of the nozzle body.

Abstract: An injection nozzle for cooling and providing counter pressure to a neck of a preform during a forming of a container from the preform. The injection nozzle includes a manifold that defines a receiving space into which the neck of the preform is received. A cavity is also defined in a part by an inner wall and an outer wall of the manifold and a plurality of ports are provided through the inner wall to communicate the cavity with the receiving space. When a cooling medium is received into the cavity, the cooling medium is directed through at least some of the ports toward the neck of the preform located within the receiving space.

Abstract: A one-step hydraulic blow molding system and method for forming a preform and a liquid filled container from the preform. The machine and method include a sealing mechanism that forms a seal primarily utilizing compressive forces in an axial direction to prevent the leakage of liquid blow medium. The sealing mechanism includes an axial end face of a forming head and an upper axial surface of a neck ring.
