  • Patent number: 9017590
    Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a combination of high tensile strength and high oxidative stability. The materials are especially suitable for use as bearing components in artificial hip and other implants. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted crosslinked UHMWPE.

  • Patent number: 8691132
    Abstract: Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process. Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

    Abstract: A method of molding an object with a mold having a transfer face includes the steps of filling, separating, re-melting, re-contacting, cooling, and removing. The filling step fills a thermoplastic material, having a temperature greater than a softening temperature of the thermoplastic material, into a cavity space in the mold having a temperature smaller than the softening temperature of the thermoplastic material. The thermoplastic material comes in contact with the transfer face and is cooled. The separating step separates the transfer face from the thermoplastic material to form a heat-insulating layer between the thermoplastic material and transfer face. The re-melting step re-melts the thermoplastic material with heat energy retained inside the thermoplastic material. The re-contacting step re-contacts the re-melted thermoplastic material to the transfer face. The cooling step cools the thermoplastic material to a temperature smaller than the softening temperature of the thermoplastic material.

A source of air is channeled through a manifold to flow about the center section of the mold and through the space between the mold and the aperture in the spool to rapidly cool the mold. Thermal chokes on each side of the center section of the mold impede heat transfer and a heat sink connected to each thermal choke serves to dissipate any heat build up. The spool may be translated along the center section of the mold to a predetermined location commensurate with a predetermined heat profile. The mold includes a passageway extending therethrough for receiving the tubing; by appropriate dimensioning, the passageway will accommodate the use of a mandrel to support the tubing to be formed, molded or welded.

    Abstract: Compositions containing at least one liquid epoxy resin, at least one solid epoxy resin, at least one propellant, at least one curing agent and at least one mica-containing filler produce expandable, thermally curable binder systems which may be used without the addition of hollow glass beads for the production of stiffening and reinforcing laminates and for the production of stiffening and reinforcing moldings. Said laminates according to the invention are suitable for the stiffening and reinforcing of components, in particular in the automotive industry, such as car body frames, doors, boot lids, engine bonnets and/or roof parts. In addition, the mouldings that may be produced from said binders are suitable for the stiffening and reinforcing of hollow metal structures, in particular of hollow car body parts such as body frames, body supports and posts or doors in the automotive industry.

  • Publication number: 20100013125
    Abstract: The invention relates to a device and a method for finishing and calibrating preforms (10) which are removed from a multiple injection tool in an unstable shape, and proposes an air cooler integrated into the water cooled cooling sleeves (21) for the outer side of the open end face of the preform (10). Particularly in the case of special preform varieties, the areas which are unsupported in the cooling sleeves (21) can be pre-strengthened on the outside, from the beginning of the transfer from the open molds (8, 9) to the removing and cooling sleeves, respectively, by means of a cooling which uses cooling air or low-temperature air. With the novel solution, the highest quality can be assured, in particular with respect to dimensional stability and the absence of pressure points under load, by means of a calibration in the cooling sleeves (32) and the treatment in the area of the aftercooling.

  • Patent number: 7611660
    Abstract: The present invention relates to an apparatus and method for cooling material during continuous vacuum forming. The apparatus includes one or more cooling regions positioned adjacent one or more vacuum regions. A rotatable support belt including perforations therein supports a flexible patterned belt. The flexible patterned belt includes apertures spaced along the length and width thereof. The one or more cooling regions provide a cooling fluid to be drawn through the apertures in the flexible patterned belt to form an area of cooling fluid on the flexible patterned belt which contacts a bottom surface of a hot material received on the flexible patterned belt in order to cool the bottom surface of the material and the flexible patterned belt. The vacuum regions are in fluid flow communication with the perforations of the support belt and the apertures of the flexible patterned belt for drawing the material onto the flexible patterned belt.

  • Patent number: 7485252
    Abstract: Apparatus and method for making a molded plastic article having a stretched and crystallized neck finish. In one embodiment, a series of platforms are carried by a conveying apparatus for transporting a series of molded plastic articles along a predetermined path of travel through one or more treatment stations. At a finish widening station, the molded article, having a relatively wide and thin-walled blow-molded body portion, and a relatively narrow and thick-walled unexpanded neck finish portion, is positioned to enable insertion of a mandrel into an open top aperture of the finish portion to widen the finish. The mandrel may include a lower heated tapered portion for expanding the finish, and an upper cooled body portion on which the expanded finish may be cooled. The article may then be sent to a finish crystallizing station having a heating device that heats the widened finish portion for a time and temperature selected to crystallize at least a portion of the widened finish.

  • Patent number: 7402268
    Abstract: A process for manufacturing a composite profile based on a thermoplastic organic material reinforced by reinforcing fibres includes making a multiplicity of continuous reinforcing yarns come into contact with a thermoplastic organic material and shaping the composite profile. Continuous yarns based on continuous glass fibres and on a first thermoplastic are brought together to be parallel and at least one consolidated tape is formed by heating them, in which tape the reinforcing fibres are impregnated with the first thermoplastic. The at least one tape is introduced into a die sized to the cross-section of the profile and at least one second molten thermoplastic organic material is simultaneously introduced into the die in contact with the tape, to obtain a profile of at least one second thermoplastic organic material reinforced by the at least one tape.
