Two new augerless additive feeders boast high accuracy at about 25% lower cost than competing units. The latest additions to the Autoload OS (On-Spec) line of feeders comes from Universal Dynamics, Inc., Woodbridge, Va. Their modular design reportedly allows for easy disassembly and cleaning for quick material changes, and they have no motor brushes to maintain. A stepper motor with a feed cylinder delivers material to the machine. These units will be on display at NPE in June. New model OS-1 is a volumetric feeder for injection molding. The OS-B loss-in-weight feeder for injection and extrusion automatically compensates for variation in bulk density of the additive. Set-up is said to take a matter of minutes using a calibration weight to set the percentage of additive. Both units have thoughput up to 55 lb/hr.
