摘要:
An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold having a mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is operable to draw liquid through the inlet and urge it into the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. A pressure compensation system can exert a clamping force on the mold in response to the pressure source. The liquid remains within the container as an end product.
摘要:
A method of fluid forming a container comprising positioning a plastic preform into a mold cavity, wherein the mold cavity defines a first configuration and a first volume. The method further includes injecting a fluid within the plastic preform at a first fluid pressure urging the plastic preform into an expanded shape. The method includes actuating the mold cavity into a second configuration and a second volume, whereby the second volume is smaller than the first volume, thereby resulting in a second fluid pressure within the plastic preform being greater than the first fluid pressure.

An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is a servo motor system that includes an inlet. The servo motor system is operable to draw liquid through the inlet and urge it into the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. The liquid remains within the container as an end product.

摘要:
A preform for use in a system for simultaneously forming and filling a container. The preform includes a finish region, a stretch initiation region adjacent to and descending from the finish region, a transition region adjacent to and descending from the stretch initiation region, a body region adjacent to and descending from the transition region, and an end cap region enclosing an end of the body region to define an interior for receiving a forming fluid. The stretch initiation region defines a wall thickness less than a wall thickness of the body region to encourage initial localized stretching in response to the forming fluid prior to stretching within the transition region or body region.
摘要:
A mold device for forming a plastic container from a preform. The preform includes at least one exterior feature formed thereon. The mold device comprises a mold defining a mold cavity, and a central exterior rod being movable within the mold cavity. The central exterior rod includes a locating feature formed therewith that is engagable with the at least one exterior feature of the preform for maintaining a central orientation of the preform within the mold cavity during forming.

摘要:
A mold device for injecting a fluid into a container where the mold device comprises a first mold portion having a first mating surface and a second mold portion having a second mating surface. The second mating surface is shaped complementary to the first mating surface. A mold cavity is disposed within the first mold portion and the second mold portion. The mold device further comprises an interlocking mating surface system disposed between or made a part of the first mold portion and second mold portion to define a fluid seal therebetween and align the first mold portion to the second mold portion in at least a first direction.
