Wittmann Battenfeld's first 2000- mm-diam., servo-electric turntable on a 1300-metric-ton, two-component MacroPower Combimould machine. Which ElboW ProblEm Do You NEED to SolvE? ProblEm cAuSE SolutioN Formation of streamers, angel hair and snake skins when conveying plastic pellets Plastic pellets skidding and/or bouncing against the outside radius of sweep elbows create friction and heat, melting pellet surfaces. Smart Elbow ® replacements from hammertek eliminate these problems by eliminating impact Unlike conventional "impact" elbows and "plugged-tee" elbows that rely on material impact to change direction, HammerTek's Smart Elbow ® design features a spherical chamber that protrudes partially beyond the desired 90º or 45º pathway, which causes a ball of pellets suspended in air to rotate, gently deflecting incoming pellets around the bend. No impact means no wear and no fines and no streamers, angel hair or snake skins. Wear and failure when conveying glass-filled, mineral-filled or other abrasive pellets Abrasive pellets hit the outside radius of conventional impact elbows at high speed, continually wearing through the elbow wall. FF-0975 Free, No-risk trial offer See how Smart Elbow® deflection elbows eliminate conventional and plugged-tee impact elbow problems—at no cost or obligation. 1-610-814-2273 45° and 90° elbows available in diameters ranging from 1.25 to 18 inch VPower vertical, servohydraulic machines that will range from 120 to 300 m.t. It is due to go on sale this month. A key feature of this machine is its low, ergonomic working height of just under 1 meter, vs. 1.1 to 1.3 m for previous models. Also impor- tant is the change from three tiebars to two, which leaves the center of the turn- table (servo-electric powered, 1300 to 2000 mm diam.) free for central supply of media through an oscillating or rotary union. Other features include convertibility of the injection unit from vertical to hori- zontal and vice versa; high clamp speeds (300 mm/sec); and a clamp design for uniform force distribution in the mold. Wittmann Battenfeld also presented new robots and auxiliaries. Both larger and smaller models were added to its Primus economy line of servo robots (reported in August Keeping Up). And the company introduced new Feedmax basic hopper receivers and S-Max screenless granulators (see September Keeping Up section). SMART MACHINES, SMART FACTORIES As might be expected, Industry 4.0 was a frequent topic during the anniversary event. The keynote speaker was Prof. Dr.-Ing. Johannes Schilp, professor at the Institute for Manufacturing Informatics at the University of Augsburg, Germany, and chairman of the Fraunhofer ICGV Research Institute for Casting, Composites and Processing Technology at Augsburg. He spoke of "data as the raw material of the 21st Century." He explained that smart products generate data during production and use, and predicted development of new business models by analyzing the accumulated data for optimization. He also said that "predictive maintenance will be the next step in self-learning systems." Wittmann Battenfeld's approach to predictive maintenance, which it calls CMS (Condition Monitoring System), is a key element of its Wittmann 4.0 program.
