    Abstract: An ultrasonic-assisted injection molding system and method for making precisely-shaped articles. A source of ultrasonic energy is positioned to apply vibrational energy to a mold cavity connected to at least one gate in flow communication with a source of molten (co)polymer. The mold is heated to a temperature of 104-116° C., and the molten (co)polymer is injected into the mold cavity. After cooling the mold until the molten (co)polymer within the gate has solidified, ultrasonic energy is applied to the mold without remelting the solidified (co)polymer within the gate until the temperature increases to 116-122° C., thereby substantially relieving flow induced stresses. The mold is then cooled until the temperature decreases to 101-107° C., and is thereafter heated until the temperature increases to 116-122° C., thereby substantially relieving any thermally induced stresses. The mold is cooled until the molten (co)polymer has solidified, thereby forming a precision molded plastic optical element.

  • Publication number: 20140374936
    Abstract: The cooling of injection molded plastic is targeted. Coolant flows into a porous medium disposed within an injection molding component via a porous medium inlet. The porous medium is thermally coupled to a mold cavity configured to receive injected liquid plastic. The porous medium beneficially allows for an increased rate of heat transfer from the injected liquid plastic to the coolant and provides additional structural support over a hollow cooling well. When the temperature of the injected liquid plastic falls below a solidifying temperature threshold, the molded component is ejected and collected.

  • Patent number: 8852471
    Abstract: A die having a plurality of cavities and a temperature sensor for acquiring a temperature value in which the number of the cavities is larger than that of electrothermal conversion elements. When viewed from a direction perpendicular to the surface of a parting line, all cavities and a temperature sensor are arranged in a region occupied by the electrothermal conversion elements. Interval between the outlines of the cavities is smaller than the minimum interval between the outline of the cavity and the electrothermal conversion element, and the shortest distance between the electrothermal conversion element and the temperature measuring portion of a temperature measuring element is shorter than the minimum interval between the outline of the cavity and the electrothermal conversion element.

  • Patent number: 8845315
    Abstract: An exemplary injection molding apparatus includes a first mold defining a passage therein, a second mold engaging with the first mold, working fluid received in the passage of the first mold, and a thermal conductive member engaged in the first mold and thermally interconnecting the first mold and the working fluid. The first mold and the second mold cooperatively define a molding chamber therebetween adapted to receive injected molten material therein. The thermal conductive member transfers heat from the first and second molds to the working fluid when the first and second molds are hotter than the working fluid, and transfers heat from the working fluid to the first and second molds when the working fluid is hotter than the first and second molds.

    Abstract: A method and apparatus for forming a grain bin sensor cable including a plurality of mold members defining a mold cavity. A pre-formed cable with wires disposed therein is placed into the mold cavity, heated, and formed into a post-formed cable. The post-formed cable includes a recessed portion and a pair of end caps. Apertures are created within the recessed portion so as to expose a portion of the wires. The end caps are generally cone-shaped and include vertical walls. The post-formed cable is removed from the mold cavity and a sensor package is coupled to the wires exposed in the recessed portion and captured between the vertical walls of the end caps. A housing is coupled about the sensor package.

    Abstract: Disclosed is a device and method for dynamic extrusion molding of plastic articles having variable micro-channel. The device mainly includes a single-screw extruder, a dynamic extrusion die, a fluid source, a water sink, a tractor, a winding device, and a data acquisition and control system. Near outlet of extrusion die, when the end portion of a syringe needle is at different positions, the inner diameter of the micro-channel of the extrusion molded plastic article is also different. When the hollow syringe core within the dynamic extrusion die performs a high-frequency short-range vibration along an extrusion direction, the inner diameter of the micro-channel of the extruded plastic articles is dynamically variable. The plastic articles of variable micro-channel of the present invention has novel structure with high dimensional accuracy, and a variety of varying patterns, it can be stably produced by simple processing equipment with high level of automation.
