Method for fabricating containers

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.

PEX Expanding Tool

An expanding tool comprising: an actuator comprising a cylindrical housing that defines an actuator housing cavity; a primary ram disposed within the actuator housing cavity, the primary ram defining an internal primary ram cavity; a secondary ram disposed within the internal primary ram cavity; a cam roller carrier coupled to a distal end of the secondary ram; a drive collar positioned within a distal end of the actuator housing cavity; a roller clutch disposed within an internal cavity defined by an inner surface of the drive collar; a shuttle cam positioned between the roller clutch and a distal end of the primary ram; an expander cone coupled to the primary ram; and an expander head operably coupled to the drive collar. When triggered, the actuator first rotates the expander head and then the actuator expands the expander head.
