  • Patent number: 9511525
    Abstract: Injection molding parts onto a carrier web located between mold halves, each mold half having a cavity, resulting in molded articles having parts on both sides of the carrier web. Polymer flow into the cavities is assisted by application of ultrasonic energy to the mold. After the molding operation, mold halves are separated, and the carrier web is advanced, or indexed, to a next position for another molding sequence. Articles produced include lenses with part of the carrier web between lens halves, and a carrier web bearing an array of molded parts.

  • Patent number: 9289931
    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.
