Wittmann Battenfeld at Fakuma 2008
Several novelties await the visitors: At a separate booth (hall A1, booth 1417), the Wittmann group will present its new, powerful high-speed TM Xpress series in combination with innovative IML applications. The new "insider solution", the concept of an integrated robot/conveyor belt inside the machine frame, will be shown for the first time.
At Fakuma 2008, Wittmann Battenfeld will show a strong presence: innovative solutions for standard as well as special applications will be on display at a total of four booths:
At the main booth in hall B1, booth 1204, application examples using machinery from the hydraulic, toggle-modular and all-electric series will be demonstrated. Two high-speed machines will produce cups for the packaging industry at the Wittmann IML booth in hall A1, booth 1417. Two standard machines from the hydraulic series will be showcased at the booth of Sagebäurer, a Battenfeld customer, in hall B3, booth 3212, and at the booth of Kunststoffinstitut Lüdenscheid in hall A5, booth 5312.
All machines will be equipped with various components from the extensive range of peripheral appliances supplied by Wittmann Kunststoffgeräte.
The hydraulic HM series - accurate and reliable
On an HM 110, Wittmann Battenfeld will demonstrate the production of a felt tip holder using a mold supplied by Stemke. This is the first mold worldwide which completely dispenses with cooling water. The principle is similar to that of a refrigerator. The refrigeration process is carried out in the mold: refrigerants evaporate in minute coolant holes, thus extracting heat from the steel. This cooling method is specially suited to small cores, which are otherwise difficult or impossible to cool, and areas inside the mold where water cannot be used. The felt tip holders are manufactured within a cycle time of 16 sec; parts removal is handled by a W801 Wittmann robot.
Wittmann Battenfeld will show two more examples of its hydraulic series at the booths of two long-term cooperation partners. At the booth of Sagebäurer, an industrial part will be produced on an HM 45/60 with 45 t clamping force. The production of an ABS bottle opener on an HM 110/210 (110 t clamping force) within a cycle time of 50 sec will be demonstrated at the booth of Kunststoffinstitut Lüdenscheid. This part will be produced by means of a foam injection molding process. A Wittmann W811 robot will handle the insertion of the metal parts, which are supplied from a bar magazine and then isolated by passing through a cylinder.
The Wittmann robot will also take care of finished parts removal and control the peripheral equipment as well.
Multi-component Technology - benefit from Battenfeld's experience
In multi-component injection molding, the customers of Wittmann Battenfeld can also rely on many years of experience. The successful concept will be demonstrated on an HM240/1330H/210S. In a 2-cavity mold supplied by IFW, a fitting with an integrated seal will be produced in a single injection-molding step within a cycle time of 60 sec. The 2-component part will be made from PP (195g) and TPE (7g). To demonstrate the "insider solution" on this exhibit, a Wittmann W823 robot will deposit the finished parts on a conveyor belt which is integrated in the machine frame. This solution favors the production of injection molded parts with minimum space requirements and thus contributes to reducing the costs. Moreover, this exhibit is equipped with "EcoPower", which achieves a substantial cost advantage by simultaneous reduction of reactive load and effective power.
In this production cell, the integration of a Wittmann W8 robot into the Unilog B6 control system of the machine will also be demonstrated for the first time.
With the option "integration into the machine control system" the robot can also be operated entirely via the Unilog B6 visualization system, in addition to the robot's operating device. This solution includes not only the display of robot screen pages, but also complete integration of the robot into the alarm system, user administration, data set management, language selection and the machine's logbook.
The hydraulic machine series of Wittmann Battenfeld offers the ultimate in performance and compact design in its performance class. All above-mentioned exhibits are equipped with the comfortable, high-performance Unilog B6 machine control system.
The PLUS 35/75 with an Unilog B2 control system is the "entry-level" model of the hydraulic series (plug & play). It will demonstrate the production of a connector housing. A sprue picker of the Wittmann series W702 will take care of parts removal.
TM Xpress - The new Fast runner
One of the highlights at this year's Fakuma is the presentation of the new TM Xpress high-speed toggle series combined with proven IML equipment from the Wittmann group. A separate booth will be dedicated to this first major joint project since the takeover (hall A1, booth 1417).
On a TM Xpress 270/1350 with 270 t clamping force, the production of square cups measuring 125x125 mm (to hold 750 ml) from PP within a 4.7 sec. cycle time will be shown. A Wittmann in-mold labeling device will handle the insertion of butterfly labels as well as removal and stacking of the cups.
The second exhibit showing the new machine concept is a TM Xpress 210/1350.
300 ml cups will be manufactured from PP in a 4-cavity mold within a cyle time of 3.9 sec. The banderole labels will also be inserted by an IML device from Wittmann.
The production cell on display represents a turnkey solution from Wittmann Battenfeld: The mold in the IML automation system comes from the French subsidiary of Wittmann, which specializes in this type of process. The peripheral equipment is supplied by Wittmann Kunststoffgeräte GmbH; the injection molding machine comes from Wittmann Battenfeld. From now on, the new TM Xpress series will be available with clamping forces ranging from 160 to 450 t.
TM - the optimized toggle design
PP felt tip pen inserts with a part weight of 0.5 g will be manufactured in a 64-cavity mold on a TM 110/350. This exhibit comes with the new, optimized toggle design.
Lubrication is reduced to a minimum by clearance of the tie-bars, so the tie-bars are free from lubricant residues. High-precision linear guides take care of guiding the moving platen, which dispenses with the necessity of adjustments for heavy molds.
EM - the all-electric series
On an EM 110/300, an exhibit from the all-electric series, Wittmann Battenfeld will show the production of a dishwasher valve made of liquid silicone (LSR) in a 16- cavity mold. The production is realized within a 23 sec. cycle time, using a mold supplied by Elmet.
Vertical R - flexible and modular
Thanks to its modular concept for the machine as well as its peripheral equipment, the Vertical R rotary table machine offers many options for combination and can be developed into a fully automatic manufacturing cell. Wittmann Battenfeld will demonstrate its system technology expertise by manufacturing a PA filter housing with a part weight of only 0.675 g within a cycle time of 6.2 sec. on a VMR 60/65 electric, featuring a rotary table and injection unit with servo electric drive. The 4- cavity mold will be supplied by Weppler Filter. The transport of finished parts within this production cell will be handled by a Wittmann W8X5 robot.
Wittmann Battenfeld service corner
Another main theme of this year's Fakuma is IT-assisted service. With a comprehensive program consisting of Web Service, Web Training and Remote Maintenance, Wittmann Battenfeld promotes worldwide communication - anywhere and around the clock. This will help its customers to save time and money. Visitors will have a first-hand opportunity to experience and test these services directly at the service corner of the Wittmann Battenfeld booth.
