New control software synchronizes filling and emptying of two accumulators on a two-sided industrial blow molder. The software from Eurotherm Inc., Leesburg, Va., ensures closedloop synchronization of the parison heads and accumulators on both sides of the machine—even when they are running different parts and shot sizes. It monitors and adjusts filling and shooting every 4 millisec. Time-compensated, positionbased control is utilized instead of velocity or pressure. This allows for large differences between the shooting profiles and strokes on the two sides. The software is available on MACO 6000 or DS/RS controls. Tel: (703) 443-0000 • www.eurotherm.com
