  • Patent number: 11325335
    Abstract: Disclosed herein is a method and apparatus for forming pellets in a non-ambient environment such as a strong magnetic field. The apparatus includes a die body, a die bottom, a short push pin, a long push pin, a press tube, and an extended push pin. A powder is loaded into the die body, which is then positioned in the non-ambient environment, and the powder allowed to equilibrate. A pellet is then formed by pressing on the extended push pin while the powder is in the non-ambient environment.

  • Patent number: 8684718
    Abstract: First, a horizontal nozzle is inserted between an upper mold section and a lower mold section in a horizontally extending state. Then, liquid resin is horizontally discharged from a discharge port of the horizontal nozzle. Thus, the liquid resin is supplied into a cavity. Thereafter the upper mold section and the lower mold section are closed. Consequently, an electronic component mounted on a substrate is dipped in the liquid resin stored in the cavity. Therefore, the electronic component is resin-sealed on the substrate by compression molding.

  • Publication number: 20030113222
    Abstract: A powder box, an arrangement for a powder box comprising an insert and a method for filling powder into a cavity formed in a die. Gas is supplied to a powder box, which is movable toward and away from a position just above the cavity. The gas is supplied through a permeable plate, which is arranged on at least one insert and which faces the interior of the powder box, so that particles of the powder in the powder box are movable relative to each other. The fluidisation of the powder shortens the filling time and results in an even particle size distribution in the cavity.

  • Publication number: 20030031749
    Abstract: A gas-assisted flow and filling device for transporting particulate material and filling die cavities includes a source of low-pressure gas for delivering gas to a chamber that is separated from a fluidizing chamber by a porous distributor plate which permits the gas to flow through the particulate material and out a vent screen so that the particulate material is permitted to flow out of the fluidizing chamber essentially free of gas and wherein the pressure of the gas delivered to the fluidizing chamber is sufficient to provide a gas bearing to said particulate material adjacent the distributor plate, but not high enough to cause turbulence in said fluidizing chamber.

  • Publication number: 20020195164
    Abstract: A fluidizing method transports particulates by gravity flow but passes the particulates through a fluidizer which is partitioned by a porous distributor plate to form first and second chambers and wherein the particulate materials pass through said first chamber which is in gaseous communication with said second chamber via the porous distributor plate. Gas is delivered to the second chamber at a pressure sufficient to generate a gas bearing between the porous distributor plate and the particulate material. The gas is permitted to migrate through the particulate material, but it is then vented to the surrounding atomosphere without causing substantial turbulence in the particulate material and to reduce tendencies for dusting and separation of the particulates into sizes.

  • Patent number: 6494704
    Abstract: Mold press apparatus for use in the manufacture of molded articles, particularly starch-bound containers and other articles. The mold press apparatus includes a planar array of female mold halves and a corresponding planar array of male mold halves. The planar array of mold halves remain substantially coplanar throughout the process of selectively mating and separating the male and female mold halves. When used to manufacture molded articles from aqueous starch-based compositions, the molds are equipped with venting means, such as vent holes and/or a vent gap, which allow for the escape of water vapor from the mold cavities defined by the mated male/female mold pairs. A suction removal system may be used to remove the molded articles from the mold press apparatus, typically from the female mold halves. The demolded articles are deposited on a conveyor system equipped with individual nests for each article.

    Abstract: A magnetic powder feeding method for feeding magnetic powder into a cavity of a pressing apparatus includes the steps of: providing magnetic powder outside of the cavity; forming a magnetic field in a space including the cavity; and moving the magnetic powder into the cavity using a force exerted on the magnetic powder by the magnetic field, while the magnetic powder is oriented in a direction of the magnetic field. In the method, the step of moving of the magnetic powder into the inside of the cavity is performed after the start of the application of the magnetic field.
