The big buzz at the upcoming Fakuma injection molding show in Germany is energy efficiency. Because of soaring hydrocarbon prices, that’s what OEMs are emphasizing. Austrian OEM Engel is showing what is describes as energy optimized, powerful machine designs. Engel will show three fully electric machines and the e-victory hybrid machine. Arbug says it has a “holistic” approach. “On one hand, the goal is to produce the Allrounder machines using as little energy as possible,” says a spokesman. “On the other, Arburg seeks to use its products and expertise in order to efficiently minimize energy consumption among its customers.” Four Arburg machines at the Fakuma bear the “e²” energy efficiency label: two from the electric Allrounder A series and two hydraulic Allrounder S series machines with electromechanical dosage drive.
