KOTTINGBRUNN, AUSTRIA (Sept. 10, 5:40 p.m. EDT) — Visitors to the K 2007 exhibit of Battenfeld Kunststoffmaschinen GmbH will see several work cells, a new Unilog B6 controller, both water- and gas-assisted molding and improved versions of the two-platen HM series, the TM toggle and the all-electric press, the EM.
Battenfeld, headquartered in Kottingbrunn, has shortened the footprint of its HM press, while giving it even more-generous platen spacing. Platens on a 400-metric-ton HM are equal in size to a 500-tonne HM of the earlier generation.
That bigger platen area comes in handy for applications with a complex mold, or where a large rotary disk is attached to the moving platen, for multicomponent molding, according to the company.
The HM is available in clamping forces of 350-650 tonnes.
Battenfeld sells multicomponent versions in all sizes, and that will be the focus at the K show, set for Oct. 24-31 in Dusseldorf, Germany.
A 400-tonne HM will be molding a polyethylene toolbox, in-mold-decorated with three-dimensional film.
The second injection unit will come down diagonally. The molding job also will demonstrate the Battenfeld Airmound gas-assist process, to form a hollow carrying handle.
Another work cell will use water-assist molding - Battenfeld Aquamold technology - to make a nylon reclining adjuster arm for car seats, on a 120-tonne HM 210/100. A Unirob R5 S robot will remove the sprue and deposit the part on a conveyor belt.
Battenfeld also will exhibit a model of its all-electric EM press with 110 metric tons of clamping force. Improvements include new servomotors and the ability to recover energy when the clamp slows down, shaving energy use. Engineers also added a sensitive tool-locking device on the clamping side.
The EM will mold nipples for baby bottles from liquid silicon rubber in a six-cavity mold with a 25-second cycle time.
Another redesigned press, a TM 210/1350 with a new toggle clamp, will mold caps for cooking oil bottles on a 48-cavity mold, running a five-second cycle.
The five-point toggle boasts changes to the clamping side, including freestanding tie bars and a moving platen with high-precision linear guides. The fixed platen now may be combined with a range of injection units. A hydraulic accumulator can crank up injection speeds up to 300 millimeters per second.
The show also will usher in Battenfeld's Unilog B6, to replace the B4. The most important functions have been integrated on just a few pages, so the B6 is easy to navigate. It employs a similar structure and the same, familiar symbols as the B4.
Many new features have been added, such as online cycle time analysis to optimize the process, and an extended quality table for complete documentation and evaluation of production data. The controller uses a Windows XP operating system, so peripheral equipment such as printers easily can be connected via USB ports. The controller even can send e-mails.
In other injection press news, a 5-ton Microsystem 50 will mold a tiny plug, on a five-second cycle, out of polyoxymethylene. A Scara robot will place connector pins into a transfer station, where a linear robot picks up four pins for each cycle and places them into the mold.
The micromolding press has a redesigned drive for the injection unit, which improves cavity filling. Also, Battenfeld improved the user-friendliness and adjustability of its Microsystem.
Also at K, a 75-ton vertical press will mold parts that are assembled into a small board game - all inside the press. Linear and industrial robots work together to insert parts quickly into the mold and do complex assembly steps.
