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： 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 μm thick on which at least 60% of the microneedles across the array are filled (i.e., completely formed).

摘要： 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.

摘要： An acoustic system for applying vibratory energy including a horn connected to an ultrasonic energy source. The horn defines an overall length and wavelength, and at least a leading section thereof is comprised of a ceramic material. The leading section has a length of at least ⅛ the horn wavelength. In one preferred embodiment, an entirety of the horn is a ceramic material, and is mounted to a separate component, such as a waveguide, via an interference fit. Regardless, by utilizing a ceramic material for at least a significant portion of the horn, the ultrasonic system of the present invention facilitates long-term operation in extreme environments such as high temperature and/or corrosive fluid mediums. The present invention is useful for fabrication of metal matrix composite wires.

摘要： A system and method for adjusting the gap between a horn and an anvil in an ultrasonic welding system includes the act of positioning a horn proximal to an anvil, so that a gap is established between the horn and the anvil. A force is applied to the horn, so as to urge the horn toward the anvil. A deformable stop is positioned at a location, such that application of the urging force causes a member operatively connected to the horn to abut the deformable stop, and to deform the stop. The urging force is iteratively adjusted during operation of the horn, so as to adjust the extent of the deformation of the deformable stop, and to maintain the gap between the horn and the anvil substantially constant.

摘要： Injection molding, parts onto a carrier web (34) located between mold halves (18,20). Flow of polymer melt into the mold is assisted by application of ultrasonic energy to the mold cavity. After the molding operation, mold halves are separated, and the carrier web is advanced, or indexed, to a next position for another molding sequence. Molding apparatus comprises a moving mold face (20), that can move toward and away from a first mold member (18) (which can be stationary) in which the mold cavity is located, a means (24,25,26,30,32) for moving and/or indexing carrier web between the first mold member and the moving mold face, means (16) to inject polymer melt into the mold cavity, and an ultrasonic system (42) providing ultrasonic energy to the mold cavity. The carrier web can transport molded parts to subsequent process steps, such as coating, drying, inspection, curing, assembly or packaging.

摘要： A method of molding a microneedle including providing a mold apparatus having a mold insert having the negative image of at least one microneedle, a compression core, a mold housing configured to allow a reciprocal motion between the mold insert and the compression core. The method includes placing the mold apparatus in a closed position, injecting polymeric material into the closed mold apparatus, compressing the injected polymeric material between the mold insert and the compression core by a reciprocal motion between the compression core and the mold insert, opening the mold, and removing a molded microneedle from the mold. The mold insert has a mold insert height and the molded microneedle has a height that is from about 90% of the mold insert height to about 115% of the mold insert height.
