    Abstract: A method for producing a duct-integrated floor-raising material includes the steps of: forming a first enclosed space, a second enclosed space, and a third enclosed space, having a molten tubular parison pressed flat and extruded from pinch-off portions by a pair of split molds, wherein portions of the parison corresponding to the pinch-off portions are welded to each other; molding the first hollow portion, the second hollow portion, the duct portion, and the waste bag in which a blow pin is pierced to outer surfaces of the tubular parison corresponding to the spaces, a pressurized fluid is blown to expand the parison, and the tubular parison is pressed against the surfaces of the split molds for shaping the parison; and cutting the waste bag to form an air intake port or an air outlet port on the duct portion.

  • Patent number: 8715562
    Abstract: A method of making a plastic container that has a tethered closure using an extrusion blow molding process includes steps of extruding a parison, capturing the parison within a mold and inflating the parison against the mold to form a container blank having a container portion, a closure portion and a tether portion for connecting the container portion to the closure portion. The tether portion, which is preferably elongated and string like, may be formed out of flash material that is created during the molding process. The resulting container is relatively inexpensive to manufacture and facilitates the plastic recycling process.

  • Patent number: 8703260
    Abstract: A catheter balloon and method involves extruded tubing with multiple layers of different durometer values, selected such that the blow up ratio (BUR) at the balloon's inner surface is increased. In one method a two stage blow mold process uses a small radius initial stage where radial growth is limited, followed by a second stage to a final dimension. A single stage blow mold process is also disclosed where the materials and processing are selected to approach the elongation to failure limit of the material. The single stage approach is preferably followed by a modified post-expansion heat set treatment to promote greater axial strength, leading to a preferred failure mode in the axial rather than radial direction.

  • Patent number: 8695203
    Abstract: Process for manufacturing a plastic fuel tank (FT) equipped with an internal accessory, by molding a parison using a mold comprising two cavities and a core, said process comprising the following steps: the parison is introduced into the mold cavities; the core is introduced inside the parison, the core having first been fitted with the accessory; the mold is closed so that the cavities come into leaktight contact with the core; the parison is pressed against the cavities by blowing through the core and/or applying a vacuum behind the cavities; the accessory is fastened to the parison by snap riveting using a device attached to the core; the mold is opened to withdraw the core; and the final molding of the parison is carried out by blow molding and/or thermoforming.

  • Publication number: 20130323447
    Abstract: Blow molded articles are made from a polymeric composition containing a mixture of polyphenylene sulfide resins. For instance, the polymeric composition may contain a linear polyphenylene sulfide resin combined with a branched polyphenylene sulfide resin. The composition can further contain a reinforcing agent, such as glass fibers, a polytetrafluoroethylene polymer, a polyphenylene oxide polymer, a silane coupling agent, and/or an impact modifier. Compositions made according to the present disclosure can have relatively high near zero shear rate melt strengths while also having high shear rate melt viscosities and high engineering stresses at a high percent elongations, making the compositions amenable to extrusion and molding processes. Compositions made according to the present disclosure are particularly well suited to molding articles with a complex shape.
