Wittmann Battenfeld at Fakuma 2011

The energy-saving fleet from Wittmann Battenfeld is completed with an HM ServoPower. This hydraulic machine with servo drive yields a reduction in energy consumption by more than 30% compared to a modern hydraulic standard machine, at a very favorable purchase price and with an average payback period of about two years. The machine also comes as an insider solution, which means that a Wittmann robot for parts removal, a conveyor belt and peripheral equipment for both upstream and downstream processing steps are integrated in the machine frame.

A front panel for a coffee machine will be manufactured on the HM 110/350 ServoPower Insider, using a single-cavity mold supplied by Wittner, Austria. This is a high-gloss visible part made of PC/ABS. The parts are produced by a variothermic process using BFMOLD TM technology. In this technology the entire space below the cavity is used for heating and cooling. This enables extremely even and, above all, quick cooling of the mold area. Therefore this technology is of interest not only in order to reduce cycle times, but also to prevent warpage and to reduce tension. Moreover, sink marks and joint lines can be prevented with the help of BFMOLD technology, above all on components with a visible surface or parts with a high-gloss surface.
The parts will be removed by a W818 Wittmann robot, which will pass them on to a camera for surface inspection. The parts inspection system shown on this line provides a method to identify surface defects independent of human observation. This system developed by PCCL (Polymer Competence Center Leoben, Austria) takes photos of the part’s surface and compares them with reference pictures. This system enables 100 % detection of surface defects independent of the presence of a human observer.

Wittmann Battenfeld’s expertise in the packaging sector will be demonstrated by an IML application. Butter tubs with 125 g capacity and 0.35 mm wall thickness will be produced from PP in a 2-cavity mold. Insertion of the banderole label and removal of the finished parts will be carried out by a Wittmann W827 robot, with a total cycle time of 2.8 seconds. The production unit is also equipped with a mold space dehydrator from Eisbär (Austria). A special feature of this application is the new, modular IML line with a high-performance drive package and an integrated CNC8 control system, which offers a number of advantages. The integration of the control system allows direct operation via the injection molding machine; intervention times are shortened substantially by the “smart removal function”. So the intervention times are reduced even further by the integrated “smart removal function” supplied as standard. A remarkable characteristic of this application is that the Wittmann group’s principle of supplying everything from a single source not only includes the machine with peripheral equipment and automation, but also the process as such and the mold supplied by the group’s own special mold-making facility.

A common feature of all machines is the Unilog B6 control system, which offers a uniform control and operation concept for easy handling of the injection molding machines, including all integrated peripheral equipment. The control system, running under Windows XP, greatly facilitates the integration of the machines in PDA systems, but above all in Internet-based service support systems. Web service and remote service systems, as well as the Battenfeld K4 production data acquisition system, are also available on all machines.

The exhibition program of Wittmann Battenfeld is rounded off by a presentation of its WebService 24/7, which was introduced at K 2010 and is now up and running around the world. WebService 24/7 stands for the online service from Wittmann Battenfeld, which is available round the clock on 7 days a week.

Visitors to the Fakuma will have an opportunity to experience the operation of WebService 24/7 first-hand via a live connection at the service center specially installed for this purpose. This service center provides information to visitors about the other services offered by Wittmann Battenfeld as well, such as customer support, application technology, training, or the Battenfeld K4 production data acquisition system.
