Athena Automation Ltd., Vaughan, Ont., is building a prototype of a rotary mold table for exhibit at NPE 2015 next March. Athena is the new injection machinery company started by Robert Schad, founder and former owner of Husky Injection Molding Systems.
The servo-driven rotary table will have 1030-mm (40.5-in.) diam. and will be integrated into the moving platen of its hybrid press, with tiebar spacing of 825 mm (32.48 in.) square. It will handle molds weighing up to 8800 lb and will deflect no more than 6 microns. It will provide 5-metric-ton ejector force and ability to turn 180° in 1 sec with a 6600-lb mold.
Mold services are supplied via a stainless-steel rotary union, with water, air, and hydraulic connections both at the center and perimeter. Other features include full ejector pattern, removable center locating ring, and shot-pin locating holes for 90° and 120° turns.
