Energy savings and faster speed than comparable hydraulic machines: that is the promise injection molding machine manufacturer Arburg is making with its new Edrive range of electric press. The company officially introduced the new machine range March 23 during its annual Technology Days open house.
This year more than 5200 plastics professionals have pre-registered for the event; Lossburg, Germany, where Arburg is based, and the towns immediately surrounding it, are home to just 8000. Arburg employs just over 2060. The Technology Days event runs through this Saturday, March 26.
The Edrive is Arburg's answer to processors' need for a machine that delivers the benefits of all-electric drive technology, but at an "attractive price" closer to comparable hydraulic machines, explained Michael Hehl, managing partner at the family-owned company. Comparing all-electric machines to hydraulic machines is an apples-to-oranges comparison, explained Herbert Kraibühler, MD technology at Arburg, in that an electrically powered machine has a drive motor on every axis. A hydraulic machine has a single synchronous drive motor and a hydraulic pump. The additional drive motors of the electric machine enable it to make various movements simultaneously, which makes for reduced cycle times....
