CHICAGO (July 21, 5:20 p.m. EDT) — Visitors to Boy Machines Inc.'s NPE booth saw a vertical injection press with a self-contained, six-axis Staubli robot loading inserts and removing the finished part, an Allen wrench.
The VV press, with 60 tons of clamping force, has both vertical clamping and vertical injection. It is also available in 24 and 38 tons.
The design uses a fixed lower platen, which creates a stable platform so the inserts do not move around when the mold closes, said Robert Koch, president of Boy Machines in Exton, Pa.
The compact, modular automation system is arranged as part of the machine footprint. “The key is, if you want to do an automation cell with one of our vertical/vertical machines, all of the cell can be mounted on the existing machine frame. You're not using any additional floor space,” Koch said.
Carl Schiffer, managing partner of Fernthal, Germany-based parent company Dr. Boy GmbH & Co., said the vertical presses have four tie bars instead of the often-used C-frame setup. That allows access to all four sides of the press, providing more flexibility for the automation, he said.
Show-goers also saw a 38-ton VV press running in the Staubli Corp. booth.
Boy also did micromolding on a 14-ton press, first molding a small gear, then degrating the part and conveying the gears through a vacuum tube to a small container. The shot weight is one-third of a ounce.
Also at NPE 2006 in Chicago, Boy showed a 60-ton model of its Ae press, which now has an electric screw drive as a standard feature, and a second hydraulic pump to do eject-on-the-fly. The press was molding a medical part on a 16-cavity mold.
