  • Patent number: 8431068
    Abstract: A process for producing thermoplastic containers (13) extrudes a plastic tube into opened movable mold parts (5, 7, 9). The main mold parts (7) form the container main part (18). The bottom parts are closed to close and weld the tube bottom end. The tube (3) is widened by a pressure gradient acting on it, forcing the tube against the wall of the mold parts (7, 9) to form the container. The mold parts are then moved into the position to open the mold for removal of the formed container (13). The container bottom is made in the form of a cup-like bottom part (19) axially extending into the container main part (18) by the bottom part being everted into the interior of the container (13) to form a bottom elevation (31).

  • Publication number: 20130101774
    Abstract: A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.

  • Patent number: 8420003
    Abstract: A tube material is formed by continuously extruding a thermoplastic resin material in the shape of a cylinder that has a thickness of 100 ?m and a circumferential length of 800 mm. After that, in a polishing process, the tube material is rubbed with a lapping tape of #2000 while being rotated in one direction at a fixed speed, so that circumferential stripes are formed on the outer circumferential surface of the tube material. Then, the circumferential stripes are thermally transferred by pressing the outer circumferential surface of the heated tube material against a mold surface that is finished in the shape of circumferential stripes by a thermal transfer process.

  • Patent number: 8418740
    Abstract: Composite sections for aircraft fuselages and other structures, and methods and systems for manufacturing such sections, are disclosed herein. A method for manufacturing a shell structure in accordance with one embodiment of the invention includes applying composite material to an interior mold surface of a tool to form a skin extending 360 degrees around an axis. The method can further include positioning a plurality of stiffeners on an inner surface of the skin. After the stiffeners have been positioned, a vacuum bag can be installed over the stiffeners and evacuated to press the stiffeners and the skin outwardly against the interior mold surface of the tool. Next, the skin/stiffener combination can be cocured to bond the stiffeners to the skin and harden the shell structure.

    Abstract: Polyoxymethylene polymer compositions are disclosed that contain an impact modifier. In accordance with the present disclosure, the impact modifier is attached to the polyoxymethylene polymer and comprises a thermoplastic elastomer containing carbonate groups, such as polycarbonate groups. In one embodiment, a coupling agent bonds the impact modifier to the polyoxymethylene polymer. Incorporation of an impact modifier containing carbonate groups has been found to produce articles having good impact resistance properties while also preserving the permeability of the material. The polymer composition is well suited to producing containment devices, especially fuel tanks.
