Sealant Equipment & Engineering Inc.'s (Plymouth, Mich., U.S.A.) recently patented Program-A-Swirl system is designed to dispense adhesives or sealants in a continuous bead or in a circular swirling pattern of closed loops, to maximize adhesion between two substrates while using less material to wetout a greater area. An oscillating nozzle assembly creates the concentric pattern and features a "self-centering" function that enables the tool to alternate, on the fly, between dispensing a swirl pattern and a consistent bead. The system can be used with a static mixer nozzle to dispense two-component, reactive resin materials or with a standard nozzle for single-component materials. Mounted as an end-of-arm tool in robotic applications or fixture-mounted in automation tooling, the system can be integrated with many of the company's dispensing systems.
