摘要： A two-part bag seal and a method for sealing a vacuum bag to a mold for a molding process. The two-part bag seal includes an elongate first seal part having a cross-sectional portion enclosing an open channel therein, and an angled cross-sectional portion having an open receptacle channel therein, and an elongate second seal part having a flexible wing portion and a flexible prong distal from the flexible wing portion, wherein the flexible prong is engageable with the open receptacle channel of the elongate first seal part.

摘要： A catalyst alarm system for resin/catalyst spray applications, the system having a first flow sensor that monitors whether a catalyst from a manifold is flowing for supply to a spay gun or other applicator at a specified minimum rate; a second flow sensor that detects if the catalyst is flowing out of a bypass conduit of the manifold, which indicates the catalyst is not being mixed with the resin; a third flow sensor that detects if the catalyst is flowing out of an over-pressure conduit of the manifold, which indicates that only a partial amount of the required catalyst is being mixed with the resin; and monitoring circuitry for providing alarm and/or control features based on activation combinations of the three flow sensors.

摘要： A three-dimensional (3D) printing system and method for printing with the 3D system. The 3D system includes a pneumatic dispense gun for mixing a thermoset resin and catalyst and dispensing a catalyzed resin to a rotary dispense valve for application of the catalyzed resin to a substrate on a movable table. The dispense gun contains a catalyst injection unit and a mixer for mixing the catalyst with the thermoset resin. The mixer is downstream of the catalyst injection unit and the catalyst injection unit includes a catalyst injector and a distribution ring surrounding the catalyst injector. One or more first pumps are provided for pumping the thermoset resin from a storage container to the pneumatic dispense gun. A second pump is provided for pumping the catalyst from a storage container to the dispense gun.
