    摘要: 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.

    摘要: A method of molding a microneedle using a mold apparatus that comprises a mold insert (210)having the negative image of at least one microneedle (12), a compression core (240), and a mold housing configured to allow a reciprocal motion between the mold insert and the compression core. The mold apparatus has an open position and a closed position. The mold apparatus is placed in the closed position and polymeric material is injected into the closed mold apparatus. The injected polymeric material is compressed between the mold insert and the compression core by a reciprocal motion between the compression core and the mold insert. Also, molding methods wherein the mold apparatus has sidewalls having an injection gate (270). Also, molding methods comprising a heated mold insert. Also, molding methods comprising the application of high frequency acoustic energy, such as ultrasonic energy, to the mold apparatus.

    摘要: The invention is a mounting system for a vibrational element. The vibrational element has a longitudinal axis, an outer surface and an axial displacement node. The mounting system includes an isolation member which has an isolation surface, an isolating body, and an engaging portion. The engaging portion is immovably secured to the isolation member and extends radially inward from the isolation body at a point radially opposite the isolation surface. The engaging portion is disposed so as to engage the outer surface of the vibrational element. Radial displacements of the vibration element are substantially decoupled from the isolation surface through the engaging portion.
