  • Patent number: 11161290
    Abstract: The present invention prevents internal cracks occurring when an impeller molded using a fiber reinforced resin is manufactured by injection molding. This method for manufacturing an impeller is provided with: an injection step of filling a cavity with a molten resin containing reinforced fibers, from a gate side into which the molten resin flows, toward an opposite-gate side opposite to the gate side; and a dwell step of applying required pressure to the filled molten resin. In the injection step and the dwell step, directional cooling is performed with a temperature gradient such that the temperature becomes lower from the gate side toward the opposite-gate side. According to this method for manufacturing the impeller, the opposite-gate side shrinks with a decrease in the temperature of the molten resin since the temperature of the opposite-gate side is lower.

  • Publication number: 20020153468
    Abstract: A bag useful for forming ice cubes or the like has a pouch-like fill chamber which may extend across the whole of the width of the bag. The fill chamber has an outlet opening connecting to the interior of the bags which comprises at least two passageways in parallel relationship. An internal seal is provided to isolate the fill chamber from the interior of the bag. The seal may comprise a zip type fastener, or a simple flap valve disposed in each of the passageways. The arrangement facilitates the handling of the bags to permit larger bags that may be filled more rapidly and with little or no air trapped within the bag, in comparison to other known bags.

  • Patent number: 6412670
    Abstract: An apparatus for making molded candles from wax pieces of old candles or new candle-making wax. The candle making apparatus comprising an electrically heatedmelting chamber from which melted wax flows into an attached dispensing chamber and a valving mechanism which, when turned by hand, allows a pre-set amount of melted wax to flow into a removable mold, eliminating the need for measuring by the user. The apparatus accomodates making candles of different volumes, whereby the removable molds may be filled by the user of the apparatus by executing a predefined number of turns of the valving mechanism. The removable mold also functions to hold the candle wick in plan, and may be made to form candles of various shapes and sizes.

  • Publication number: 20020047220
    Abstract: An apparatus and method for filling a mold for casting optical lens. Two molding shells and a closure member form a mold with a molding cavity. To fill the mold a fluid lens-forming material is introduced into the molding cavity through a casting opening formed in the closure member. Air is venting out during the filling process through a venting opening also formed in the closure member. Both the casting opening and the venting opening are located in the upper portion of the molding cavity but spaced apart from each other at an acute angle.

  • Patent number: 6375148
    Abstract: A method of fabricating a needle via conformal deposition in a two-piece mold includes the step of attaching a top mold member to a bottom mold member such that the top mold member and the bottom mold member define an enclosed, elongated needle trench with a deposition aperture. A conformal substance, such as polysilicon, is then passed through the deposition aperture such that the conformal substance is deposited within the enclosed, elongated needle trench to form a needle. The method is used to form needles with prongs, multiple channels, multiple ports, barbs, strength enhancement features, and circuitry.
