Plastic Metal USA Ltd., which distributes SyncroSpeed motor controls, reports the results of a trial on a 650-ton Husky injection molding machine, with two variable displacement pumps.
The result: a fixed reduction in motor speed to 25 Hz, reducing power consumption by 16.2 percent, with no change in injection fill rate or overall cycle time, according to Plastic Metal USA.
Energy savings came from reduced speed that has a corresponding increased swash position of the pumps, reduced speed resulting in less volumes recharging the accumulators, therefore reducing the final charge pressure, and eliminating.
Plastic Metal USA is in Bayside, N.Y.
