  • Patent number: 11040477
    Abstract: A method of fabricating a container from a substantially tubular preform. The preform is preheated to a temperature above the glass-transition temperature of the preform and placed in an expansion zone configured to accommodate the preform and in fluid communication with the nozzle of an injection head. The expansion zone is disposed adjacent to the nozzle and about the longitudinal axis defined by the injection head. A volume of an injection liquid is injected from the injection head into the preform cavity of the preform while the preform is in the expansion zone and the preform is expanded, while still in the expansion zone, into a container. Concurrently with the injecting and expanding of the preform, the preform is heated by energizing a plurality of infrared-emitting elements disposed about the preform and projecting infrared radiation into the expansion zone.

  • Patent number: 10300652
    Abstract: A method for fabricating containers wherein a molding apparatus is provided having a plurality of mold segments, each of which has two substantially opposite faces that form a mold cavity when abutted against an opposite face of an adjacent mold segment. A first mold segment is passed through a manipulation zone at an increased speed to open the mold cavity between the first and second mold segments. After a preform is positioned within the mold cavity, a second mold segment is passed through the manipulation zone at an increased speed to abut a face of the first mold segment against an opposite face of the second mold segment. A volume of a liquid is next injected into the preform, expanding the preform and forming the container. These steps are repeated and a container produced during the previous iteration is removed during an extracting step in an extracting manipulation zone.
