  • Patent number: 10155334
    Abstract: A method of molding a composition comprising a thermotropic liquid crystalline polymer (TLCP) comprising mesogens; providing a mold having a mold cavity, with a feature cavity comprising a fine feature chamber; heating the composition to form molten composition; filling the fine feature chamber with molten composition moving at a flow velocity that causes flow alignment of at least a portion of the mesogens in the molten TLCP filling the fine feature chamber, relative to a flow direction of the moving molten composition; and solidifying the molten composition such that mesogens of at least the solidified TLCP in the fine feature chamber maintain their flow alignment. A molded article comprising a body and a 3-dimensional structural feature protruding out from the body and comprising a fine feature element having a minor dimension, with TLCP mesogens across the minor dimension being in a flow aligned state.

  • Patent number: 10105524
    Abstract: The present application provides articles (10) having a polymeric substrate (12) with a plurality of solid and/or hollow microneedles (20) extending therefrom. Each solid microneedle is formed by a molding process and the microneedle has body with first (30) and second cavities (40) extending therein. The hollow microneedles are formed by removing a portion of the polymeric material disposed between the first cavity and the second cavity. A method for determining the location of a microneedle in an article comprising solid microneedles is also provided. The method comprises directing electromagnetic radiation toward an article comprising a plurality of microneedles and imaging the article.

  • Publication number: 20180222143
    Abstract: A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.

  • 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.

  • Patent number: 8637136
    Abstract: Articles enabled by an injection molding process that molds parts on a carrier web located between mold halves and uses ultrasonic energy to assist flow of polymer melt into the mold cavity. One such article is a carrier web having a high density of molded parts, i.e., bearing an array of molded articles adhered to the web in rows and columns, the articles being spaced closer (center-to-center or edge-to-edge) than the diagonal spacing between articles in the next adjacent row and next adjacent column. Another such article is a microneedle array on a land no more than 250 ?m thick on which at least 60% of the microneedles across the array are filled (i.e., completely formed).
