As noted briefly in September’s Starting Up section, Milacron Holdings Corp., Cincinnati, introduced its new Uniloy all-electric M-Series shuttle at last month’s K 2016 show in Dusseldorf. Here are more details:

Built at Milacron’s brand-new plant in the Czech Republic, the M-Series is the first unified platform that combines the engineering resources of Milacron’s Italian and German teams, notes Massimo Davoli, global product manager for shuttle presses. This third-generation all-electric shuttle is suitable for bottles and technical parts from 100 ml up to 20 liters. Davoli notes that one key benefit is modular design that allows selection of a wide range of clamp forces and strokes and various configurations, so a machine can be “customized with standard components.” This results in faster delivery. He also notes that this is the first Uniloy machine with a larger touchscreen operator interface that will be common to all Milacron injection and blow molding presses.

Another important feature of the M-Series, according to Davoli, is increased reliability without sacrificing performance, through simplified design of the clamp, shuttle movements, and bobbing mechanism of the extruder. A third benefit is improved repeatability through the incorporation of a zero-backlash precision gearbox and AC brushless motors with absolute encoders.

The model at the show was an M20.75 ED, a double-sided press with a 20-metric-ton clamp, 750-mm shuttle stroke, and five parisons. It produced a 32-oz detergent bottle (47 g) with handle on a 12-sec cycle.
