System Servo series. They do cost a bit more than standard Systec models, but Sumitomo says 60-70% of those machines are being sold with servo pumps anyway. • KraussMafei (U.S. ofce in Florence, Ky.; kraussmafeigroup.us) has revised and upgraded its CX Series in smaller sizes (35 to 160 m.t.) with servo hydraulics now standard. A company ofcial said, candidly, that there is no increase in list price, but discounts might be less than before. • Haitian of China (U.S. representative is Absolute Haitian in Worcester, Mass.; absolutehaitian.com) has new smaller models of its servo-hydraulic, two-platen Jupiter II series, starting at 450 m.t. • Engel (U.S. ofce in York, Pa.; engelglobal.com/us) still ofers servo hydraulics as an option, but it's one that 70% of its hydraulic machine customers purchase. • Boy Machines (U.S. ofce in Exton, Pa.; boymachines.com) already makes servo hydraulics standard on all its machines except its very smallest XS model (10 m.t.). Boy sees no further Some people call it the "mini K Show." The Fakuma exhibition in Friedrichshafen, Germany, used to be considered a local plastics trade fair for German machinery exhibitors to reach an audience in southern Germany, Austria, Switzerland, and the Czech Republic. But the show has grown continuously in importance, and Fakuma 2014 attracted nearly 46,000 visitors from 117 countries and 1772 exhibitors from 36 nations. It's still predominantly an injection molding machinery show. Among the equipment introductions at Fakuma, four categories stood out because they were highlighted by multiple exhibitors. 1. SERVO PUMPS ARE THE NEW STANDARD FOR HYDRAULICS Most machine builders are coming around to the idea that the future of hydraulics in injection molding— and it probably does have a future for a long while to come—is using pumps with variable-speed servo or frequency drives. For example, ofcials from Arburg (U.S. ofce in Newington, Conn.; arburg.com) ack- owledged that "there is a clear trend toward servo hydraulics for energy savings and noise reduction." Confrming that trend, several machine builders introduced presses with servo hydraulics as standard instead of an option that used to cost around 10% additional but provided energy sav- ings nearly equivalent to those of an all-electric machine. • Wittmann Battenfeld (U.S. ofce in Torrington, Conn.; wittmann-group.com) introduced the SmartPower series that will replace the conven- tional hydraulic HM series in sizes from 25 to 120 metric tons at no extra cost. They reportedly cost about 20% less than an all-electrics for equivalent energy consumption. • Sumitomo (SHI) Demag Plastics Machinery (U.S. ofce in Strongsville, Ohio; sumitomo-shi-demag.us) brought out the By Matt Naitove Executive Editor Key Themes from the Fakuma Show Servo-driven pumps are becoming standard equipment on new press lines and may not add to the list price. Servo-hydraulics, servo sprue pickers, electronic water-fow monitoring/control, and exotic multi- process cells were the headliners in Friedrichshafen. Servo-powered hydraulics are becoming standard on press lines like Wittmann Battenfeld's new SmartPower series and Sumitomo Demag's Systec Servo, of which the activeDrive servo pump motor is shown above. 10 DECEMBER 2014 Plastics Technology PTonline.com FA K U M A 2 0 1 5 Close -Up On Technolog y
