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.

  • Patent number: 8808611
    Abstract: In effecting the stretching by using a stretch rod in a method of producing a biaxially stretched polyester bottle, the air is blown into the preform at such a flow rate that the preform does not come in contact with the stretch rod but the end thereof and does not come in contact with the surfaces of the mold, either. There can be produced a biaxially stretched polyester bottle having an average thickness of about 0.05 to about 0.2 mm or having a further decreased thickness using a resin in decreased amounts and having a decreased weight without developing burst or whitening caused by over-stretching, without forming ring-like thick portion yet maintaining a good yield and efficiency.

  • Publication number: 20140213970
    Abstract: A process for forming a catheter balloon includes subjecting a tubular parison in a mold to molding fluid pressure. The resulting catheter balloon includes a balloon portion having two ends and tubular leg portions extending from either end. The ends of the balloon portion are tapered to the tubular leg portions. The tapered ends have alternating elongate areas of greater and lesser resistance to deformation displaced circumferentially about the tapered ends. The elongate areas of greater and lesser resistance to deformation can include ridges which are either longitudinal or spiraled or rods imbedded in the body of the balloon. While in the mold, the tubular legs are drawn axially sufficiently to form permanent creases in the tapered ends. This drawing may be sufficient to cause the material of the tapered ends to exceed the yield strength, particularly with the balloon material in a malleable state.

  • Patent number: 8790568
    Abstract: Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform.

  • Publication number: 20140203481
    Abstract: A method of manufacturing a container from a blank in a stretch blowing assembly equipped with a mold provided with a wall and a mold bottom axially movable between an extended position and a retracted position and a stretch unit having a rod axially movable with respect to the wall and a device for controlling the movement of the rod. The method involves a stretch blowing phase; a boxing phase during which the mold bottom, initially in the extended position, is moved towards its retracted position, the boxing phase having a retraction operation including controlling a movement of the rod in synchronization with the movement of the mold bottom, or releasing the rod to allow the free axial movement thereof.

  • Patent number: 8747726
    Abstract: A syringe for use in a pressurized injection of a fluid includes a syringe barrel including a polymeric material having undergone expansion via blow molding. An inner diameter of the syringe barrel can, for example, be sufficiently constant (over at least a portion of the axial length of the syringe) that a plunger slidably positioned within the syringe barrel and in generally sealing contact with an inner wall of the syringe barrel can be used within the syringe barrel to generate a pressure of at least 1 psi within the syringe barrel. In several embodiment, the inner diameter of the syringe barrel is sufficiently constant to generate a pressure of at least 100 psi, at least 300 psi, or even at least 500 psi within the syringe barrel.

  • Patent number: 8747728
    Abstract: A polymer endoprosthesis is fabricated by a combination of injection molding and blow molding which form a tubular substrate of polymer material, followed by laser cutting, crimping and sterilization. After the injection and blow molding processes, a subtractive process is performed on the tubular substrate to transform it into a stent having a network of stent struts. The tubular substrate can be made in an injection mold and blow mold which are attached to each other. The transition from injection molding and blow molding can be performed while the injection molded substrate remains at a temperature at or above Tg of the polymer material.

  • Patent number: 8721940
    Abstract: A method for producing a vessel by stretch blow-molding in a mold from a preform made of plastic material includes heating the preform and introducing the preform in the mold. The preform is stretched by a rod displaced at a predetermined stretching speed. At a pre-blowing cue, the electrovalve is opened for establishing a communication between the inside of the preform and a gas source at a predetermined pre-blowing pressure and a pre-blowing flow rate. Pressure inside the preform is measured and a pressure peak is detected. The moment at which this pressure peak occurs and the corresponding pressure inside the preform is stored and compared with a predetermined moment and pressure for a theoretical pressure peak. Depending on the result, at least one of the following are modified: pre-blowing pressure, pre-blowing flow rate, pre-blowing cue, stretching speed, and heating temperature.
