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： 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 making injection molded microstructured articles for drug delivery and tissue fluid sampling by injection molding the articles onto a carrier web to then convey the articles during the manufacturing process. The molded articles are attached to the web by closing the mold over a portion of the web prior to injection. This is particularly beneficial where the article has a highly sensitive surface, such as an array of delicate microneedles for drug delivery or fluid sampling. It also facilitates subsequent processing, which may include applying drug coatings and other processing.

摘要： Fuel cell systems incorporate end plate assemblies used to compress the fuel cell stack and/or to collect current from the fuel cell stack. A fuel cell system includes a fuel cell stack having fuel cells stacked in a predetermined stacking direction. Multi-function or multi-region compression end plate assemblies are disposed at the ends of a fuel cell stack. A multi-region compression end plate assembly involves compression mechanisms configured to preferentially compress separate areas of the fuel cell stack. A multi-function end plate assembly employs a current collector passing through an end plate to collect current from the fuel cell stack. The current collector may be used to preferentially compress a region of the fuel cell stack.
