So far, Boy Machines Inc., Exton, Pa., has offered its latest drive technology on machines from 35 to 90 metric tons. It is coming in 2012 to the Boy 22 with 22-ton clamp. The Fakuma show in Germany last month saw the debut of the Boy 22 E with servo-motor pump drive. Besides saving energy and reducing noise, its higher throughput provides even faster and more dynamic movements. Flow and friction resistance in the clamp have also been optimized, reducing dry-cycle time. The show machine produced PS airline cups with a shot weight of 10.7 g in a cycle of about 3.8 sec.
