A line of hydraulically powered unscrewing devices for parts with right- and left-handed threads is new from Exaflow GmbH in Germany, offered here by Diemould Service Co. (DMS), Windsor, Ont. These compact hydraulic units replace bulkier rack-and-pinion systems. Their hydraulic motors operate at up to 2450 rpm. Each unit comes with high-precision induction sensors. Thread depth is determined by a fixed stop on the mold. The single drive unit weighs 13.2 lb and measures 110 x 110 x 230 mm, while the dual drive weighs 19.8 lb and measures 190 x 85 x 230 mm. The unscrewing units support long thread depths and are suited to high-volume production.
