  • Publication number: 20080308220
    Abstract: A film coated with a metal foil is embossed beforehand by a film shaping male mold to impart to the film a shape conformed to a formed article. The film shaping male mold and an injection molding male mold are slid, and injection molding is performed, with the embossed film coated with the metal foil being sandwiched between the injection molding male mold and a shaping female mold. As a result, the metal foil of the film coated with the metal foil is transferred to a product having a deeply concavo-convex surface, without damage to the metal foil, with the quality of the product being ensured.

  • Patent number: 7431578
    Abstract: The invention provides a vertical injection molding machine capable of periodically feeding lubricant to sliding portions of the turntable to maintain a substantially constant turntable slide resistance and also capable of determining the position of the repeatedly revolving turntable. During operation of a vertical injection molding machine 1, lubricant is periodically fed from a pump 30 to slide portions S of the revolving turntable 14 so as to maintain the slide resistance of the sliding portions S substantially constant. Further, a motor control means 51 resets the count of pulses output from an encoder 29 at a timing at which the number of revolutions of a servomotor 25 and the number of revolutions of the turntable 14 are integers, so that it is possible to prevent pulse errors from accumulating even when the turntable 14 is revolved many times in the same direction.

  • Patent number: 7226282
    Abstract: A method of manufacturing a charge roller utilizes a foam rubber substance where epichlorohydrin oxide rubber and an acrylonitrile butadiene rubber are mixed at a ratio of 5:95, or utilizing a crosslinking rubber substance consisting of epichlorohydrin oxide rubber and acrylonitrile butadiene rubber having a polar low molecular polymeric characteristic, thus allowing the charge roller to maintain a low volume resistivity of 107 ?cm to 108 ?cm. As a result, the surface of a photosensitive drum can be charged by a minimum charging voltage, to thereby significantly reduce an amount of ozone. A method of manufacturing a charge roller employs peroxide as a cross linking agent for rapidly cross-linking molecular chains between an epichlorohydrin oxide rubber and acrylonitrile butadiene rubber forming a main composition of a foam rubber substance.

A front plate supporting a heating barrel is fixed to a base with a height-adjusting mechanism located in-between. A rear plate is connected to the front plate by connecting members symmetrically arranged. The injection screw inserted in the heating barrel is rotatably supported by a pusher plate to which a ball nut is fixed. A ball screw engaged with the ball nut is rotatably supported by the rear plate. The pusher plate is supported and guided by the support/guide member, and moves forward to inject resin by the rotation of the ball screw. The support/guide member is supported by a supporting member fixed to the front plate.

  • Patent number: 7198480
    Abstract: An injection molding system has a plurality of movable sub-clamping units each having a mold therein and a main clamping unit for clamping the mold in the sub-clamping unit. Each of the sub-clamping units alternately enters the main clamping unit for only a filling process to receive the melted resin material from an injection unit. Each sub-clamping unit clamps the mold by its own clamping mechanism and moves to the main clamping unit where the mold is further clamped by a higher clamping pressure by the main clamping unit during the filling process. Each sub-clamping unit is retracted from the main clamping unit immediately after the filling process and stayed outside of the main clamping unit through the holding process and the cooling process, thereby dramatically improving the molding production efficiency.

  • Patent number: 7195473
    Abstract: Thermoplastic polymers, rubbery polymeric components and reinforcing fillers are mixed and heated to a range of 380° F. to 440° F. The resulting mixture is then fed into a BANBURY mixer, with the resulting mixture fed into a diverter feeding two molds. The velocity of the piston of each mold being filled is controlled to thereby control the density of the molded product along its length (BANBURY is a registered trademark of Farrel Corporation). As each mold is filled, it is deposited in a cool water bath (50° F.–60° F.) while the next mold is being filled. The molds are sequentially transferred to an air cooling rack to complete the process. A texture, generally comprising indentations perpendicular to the longitudinal axis on the molded object, provides a frictional surface between the railway crosstie and the ballast beneath the crosstie.
