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.

Abstract: A method of forming a container includes providing a preform of the container. The preform has a wall with an interior region and an exterior region. The method also includes disposing the preform in a mold cavity wherein the mold cavity has a mold surface. Furthermore, the method includes introducing a substance into the preform to expand the preform toward the mold surface. The interior region of the wall has a first interior temperature prior to the introduction of the substance and a second interior temperature after the introduction of the substance. The exterior region of the wall has a first exterior temperature prior to the introduction of the substance and a second exterior temperature after the introduction of the substance. The method further includes controlling the first interior temperature to be greater than the first exterior temperature prior to the introduction of the substance.

Abstract: A method and apparatus for forming a container including introducing an indicia material into an injection stream between an inner layer and an outer layer to form a preform. The method further includes shaping the preform into a container such that the container defines visual patterning along at least a portion thereof.

Abstract: Hot fill and retort stable containers can be made by blowmolding parisons made with polyalkylene terephthalate and a sufficient amount of nucleating agent under conditions that include heated molds, directional cooling air on container stress areas from vents formed into a push rod that is extended into the molded container while still in the heated mold, and an adequate residence time to grow the desired degree of crystallinity.
