Sealant Equipment & Engineering Inc. (Plymouth, Mich.) has developed the Pneumatic Servo Dispensing (PSD) system, a positive rod displacement metering system that combines the cost efficiency of a pneumatic drive motor with the controlling accuracy of a servo drive motor. The system integrates a pneumatic drive motor and servo package to provide precise metered volumes, accurate flow control and consistent bead profiles. The pneumatic cylinder and positive displacement meter are assembled into a single metering module for floor, robot or pedestal mounting. It is operated by its own control panel, or by integrated controls with dispensing software for a smaller footprint. The system is designed for dispensing applications such as adhesive bonding, casting, filling, gasketing, molding, sealing and other operations. Dispensable materials include adhesives and sealants such as one-part epoxies, mastics, silicones, urethanes and abrasive materials.
