Patent number: 8062016Abstract: An injection molded article with which a sheet-like material, such as a decorative sheet, is integrated is manufactured without causing damage to the sheet-like material. A molten resin injected into a mold cavity, passes smoothly a peripheral edge of the mold cavity, and flows into a groove portion without accumulating in the vicinity of the peripheral edge. When cooling the molten resin, the temperature of the molten resin in the groove decreases more quickly than the temperature of the molten resin in the mold cavity, because the volume of the groove portion is smaller. As a result, the viscosity of the molten resin in the groove portion and in the vicinity of the peripheral edge of the mold cavity is increased rapidly, preventing a further volume of the molten resin from flowing into the groove portion. The sheet-like material in the vicinity of the peripheral edge is covered by the resinous material of diminished fluidity and protected against exposure to heat and/or pressure of the molten resin.Type: GrantFiled: August 8, 2006Date of Patent: November 22, 2011Assignee: Moriroku Company, Ltd.Inventors: Hideki Baba, Koji Akasaka, Daiju Kawakami

Patent number: 8029263Abstract: A mold assembly includes a support table mounted for rotation within a vacuum chamber. A plurality of hollow part molds is radially disposed about an axis of rotation of the support table. Each part mold has fiber architecture disposed between an inflatable bladder and internal walls of the part mold. A first motor rotates the support table and resin is urged by centrifugal force to flow along the length of each part mold until the fiber architecture is thoroughly impregnated with resin. A second motor spins each part mold about an axis of rotation of the part mold to ensure that the resin migrates radially outwardly relative to the interior wall surface of each part mold. The resulting product is a monolithic, seamless part having no voids.Type: GrantFiled: July 17, 2009Date of Patent: October 4, 2011Inventors: Marc A. Quenneville, Stephen M. Quenneville

Patent number: 8029714Abstract: A method of manufacturing a radial shaft seal assembly. The method includes the step of stretching an inner diameter of a ring-shaped polytetrafluoroethylene seal radially outward from an axis with a mandrel to a first stretched condition on a mold core element. The method also includes the step of defining a substantially enclosed mold cavity around the polytetrafluoroethylene seal stretched over the mold core element with at least one mold element. The method also includes the step of locating a rigid casing within the mold cavity spaced from the stretched polytetrafluoroethylene seal. The method also includes the step of introducing a liquefied rubber elastomer into the mold cavity. The method also includes the step of molding the liquefied rubber elastomer under heat and pressure such that the rigid casing and polytetrafluoroethylene seal in a stretched state are bonded to a solid rubber elastomer member.Type: GrantFiled: July 6, 2007Date of Patent: October 4, 2011Assignee: Federal-Mogul World Wide, Inc.Inventor: Frederick R.

Publication number: 20110180962Abstract: A headset can include a cable structure connecting non-cable components such as jacks and headphones. The cable structure can be constructed using a molding process. Different approaches can be used to ensure that a conductor bundle extending through the cable structure remains centered within the cable structure during the molding process. In some cases, a movable tube can be placed in the mold such that the conductor bundle is retained within the tube. As material is injected into the mold and reaches the tube, the tube can be displaced and progressively removed from the mold. Alternatively, the movable tube can be constructed such that the tube may combine with injected material to form a shell of the cable structure. In some cases, gates from which material is provided in the mold can be positioned and controlled to facilitate the injection of material in the mold while maintaining the centered position of the conductor bundle.Type: ApplicationFiled: January 25, 2011Publication date: July 28, 2011Applicant: Apple Inc.Inventors: Jonathan Aase, Cameron Frazier, John Thomas

Patent number: 7985003Abstract: A forming mold of a light-emitting member includes a frame, an upper mold and a lower mold, and the frame is provided with carriers, pins and supporting portions. The upper and lower molds match with each other to provide a forming space for the base of the light-emitting member. The forming space contains the carriers and a part of the supporting portions. One or more projections are disposed at the position where the brinks of the upper and lower molds contact the supporting portions. After injection molding, the burrs formed by a plastic material along the supporting portions can be concealed in the recesses that are formed corresponding to each of the projections, thereby reducing the influence of the burrs on the external size of the base.Type: GrantFiled: August 25, 2008Date of Patent: July 26, 2011Assignee: Lextar Electronics Corp.Inventors: Wen-Lung Su, Chin-Chang Hsu, Hsuan-Chi Liu
