Düsseldorf, Germany — Some injection molding machines at Dr. Boy GmbH & Co. KG are getting a hybrid option.
The Germany machinery maker said it will offer customers the optional servo-electric drive for the injection unit on its Boy E presses ranging from 60-125 metric tons.
In general, the company's E series machines are equipped with "a very energy-efficient working servo-motor pump drive," Thomas Breiden, Boy's head of marketing and documentation, said at K 2019 in Düsseldorf.
The word "hybrid" is added when the injection molding machine is equipped with the eSP injection unit, as the company refers to it. The eSP injection unit offers advantages including shorter cycle times and high metering quantities, Breiden said.
"Some years ago, we [had] an option [for a] servo-electric screw drive, but with this option only rotative movements of the screw are possible," he said in emailed responses before the K show. "With our new hybrid option, also axial movements are possible, independent from the machine hydraulic."
The optional servo-electric drive will be available to customers worldwide in 2020.
