Injection Molding: Largest Wittmann Robot Yet Handles 100 kg
French molder uses its 3-m demolding stroke and large payload capacity to mold waste bins.
The biggest Cartesian robot yet built by Wittmann Battenfeld is molding waste bins at Belli in Bellignat, France. The model W873XL was chosen because of its demolding (“X”) stroke of 3 meters (3.28 ft) and ability to heft parts weighing up to 100 kg (220 lb). With that large demolding stroke, says Belli general manager Eric Chanal, “We don’t have to work with only partial mold openings.” He also notes that replacing the six-axis articulated robot previously used for this application frees up much more floor space for palletizing. And the Wittmann robot uses grippers that handle large parts with less extraction time. “Last, but not least, we are really fond of the Wittmann TeachBox console, because of its usability, making faultless robot programming so easy.”
Belli in France molds large waste bins with customized Wittmann Battenfeld robot, the largest the firm has built.
The customized design of this robot was adapted by Wittmann Battenfeld from its standard W873 model. Belli is so happy with this unit that it plans to order an even bigger robot.
INJECTION MOLDING AT NPE: Molding Exhibits Show Off Cell Integration with Multiple Processes & Operations
If you’re interested in lightweight composites, IML, LSR, multi-shot, inmold assembly, barrier coinjection, micromolding, variotherm molding, foams, energy-saving presses, robots, hot runners, and tooling—they’re all here in force.
An injection molding robot is no better than its end-of-arm tooling (EOAT). All the potential benefits of robots--increased productivity, quality, and safety, as well as reduced scrap--are influenced by the effectiveness with which the EOAT does its job. End-of-arm tooling may perform tasks as simple as sprue picking and demolding or as advanced as degating, insert loading, parts reorientation, and assembly.
Often overlooked as a small part of an automation system, clever end-of-arm tooling techniques and designs can improve part quality, heighten efficiency, and eliminate headaches for any molder.
