Injection Molding: New Models of Economical Robots
Wittmann Battenfeld expands its Primus robot line with smaller and larger models.
Wittmann Battenfeld (U.S. office in Torrington, Conn.) has added larger and smaller models to its Primus series of simple, economical pick-and-place robots. These units, adapted from the W8 series, have three servo axes and a limited range of options. The first unit, Primus 16, has a payload capacity of 5 kg (11 lb) and was introduced at K 2016. The second model, Primus 14, debuted at Fakuma 2017 and was also shown at NPE2018; it can carry 2 kg (4.4 lb).
Now there are also the Primus 10 (1.5 kg/3.3 lb) and Primus 26 (10 kg/22 lb), as well as Primus 26T with telescopic vertical axis. The largest models are suitable for injection presses up to 400 metric tons, vs. a maximum of 250 m.t. previously.
All Primus models come with up to four vacuum circuits and the R8 TeachBox control.
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.
Next month’s mammoth triennial plastics show in Düsseldorf, Germany, challenges injection molding machine builders to demonstrate technological leadership in addressing the needs of the marketplace.
At the big “K” Show next month, top billing goes to new all-electric machines aimed at every segment of the market, from general-purpose to high-end.
