of-arm tooling (EOAT) and its Wittmann 4.0 program for networking all its equipment together to share data and integrate the various controls. "We immediately saw the value of having all the equipment talk to each other—how could we pass that up?" DMT personnel made multiple visits to Wittmann Battenfeld's U.S. headquarters in Torrington, Conn. (, including three days of training on use of the machine and robot. DMT visited another Wittmann customer to gain further insight, and Wittmann offered other customer contacts as well. Finally, with the installation last August of an EcoPower 330-ton all-electric press, W-833 Cartesian robot, chiller, TCU, dryer, blender, and hopper loader, DMT became the first U.S. company to install a Wittmann 4.0 system using the company's latest Unilog B8 injection machine control as the hub for integrating the cell components. Wittmann Battenfeld has over 30 U.S. customers using various elements of Wittmann 4.0, but DMT is the first with the very latest technology. IMPLEMENTING 4.0 Like most molders to date, DMT has imple- mented just some parts of the overall Wittmann 4.0 ecosystem. One is the inte- gration of data and settings for the robot, blender, and TCU with the Unilog B8 press control. Bob Parkhurst, DMT's mainte- nance manager, likes the large B8 touch- screen, which Wittmann Battenfeld cus- tomized for his firm. It shows on one screen all barrel and hot-runner tempera- tures, cooling time, pack/hold settings, blender settings, and TCU temperatures. Parkhurst likes that he can now see key process data on one screen and not have to walk around the cell to examine screens on the robot, blender, or TCU. (The central chiller and dryer, which supply all three injection presses, are not integrated with the Unilog B8 control.) He can also see data and modify settings on all the cell components from a computer in his office. Also valuable is the ability to load the setups for the machine, robot, blender, and TCU together as one recipe when a mold is changed, which happens up to three times a week. That saves consider- able time, Parkhurst says. Mark Bettke and Stan Watson (l.), technical director, with samples of DMT's sharpening products.
