WITTMANN BATTENFELD presents itself as a competent partner for the plastics industry
WITTMANN BATTENFELD at the Equiplast in Barcelona
Spain is an important market for the Wittmann group for machinery, automation and peripheral equipment. Accordingly, the company's presentation of products and applications at the Equiplast in Barcelona is both extensive and competent. The main ideas which WITTMANN BATTENFELD aims to communicate to trade visitors by its demonstration of highly efficient machines and at this year's Equiplast in Barcelona are cost-efficiency and energy-efficiency, with simultaneous top quality in finished parts for maximum customer benefit.
EcoPower 300/1330 and MacroPower 650/5100
At the Equiplast in Barcelona WITTMANN BATTENFELD will show the new MacroPower 650 and the new EcoPower 300. These machines are an extension of the successful machine series of the PowerSeries - down to a smaller size in the case of the large machine, and up to a higher clamping force range for the all-electric machine. As a result, the MacroPower is now available with clamping forces ranging from 650 to 1.000 t, the EcoPower from 55 to 300 t. Modular, compact design, energy-efficiency, an open structure for quick mold change and high precision are the distinctive features of the PowerSeries.
At the Equiplast, a fitting with a part weight of 130 g will be produced from PP on an EcoPower 300 with a mold supplied by the IFW group. The cycle time including robot operation is 30 seconds, if the mold-maker's special XCS cooling system is used, or 35 seconds with standard cooling. The parts are removed and deposited on a conveyor belt by a WITTMANN W821 robot.
On a MacroPower 650/5100 with servo drive, stackable carrier boxes will be produced. Parts quality is ensured by SKZ inline thermography. Any deviations in part dimensions caused by temperature or material fluctuations are compensated by closed-loop correction of the mold temperature.
Inline thermography is a process developed in cooperation with the SKZ (Das Kunststoff-Zentrum) in Wurzburg, which is exclusively marketed and distributed by WITTMANN worldwide. On the exhibit, a WITTMANN W843 linear robot presents the parts to the camera in several different positions immediately after demolding. The evaluation is displayed on a monitor, any deviations from the release status are visualized and calculated according to segments for the connected WITTMAN FLOWCON flow regulator. This ensures that any temperature adjustments that may be necessary are effected in real time.
HM ServoPower with Insider automation, BFMOLD and surface inspection
At the Equiplast the energy-saving fleet from WITTMANN BATTENFELD is completed with an HM ServoPower with a clamping force of 110 t. 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 BFMOLDTM 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(TM) 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 GmbH
The WITTMANN group based in Vienna/Austria is one of the world's leading manufacturers of robots and peripheral equipment for the plastics industry. The WITTMANN product portfolio includes robots and automation equipment, automatic material loaders and material dryers as well as equipment for plastics recycling, mold tempering and cooling, and volumetric and gravimetric metering appliances.
In 2008, WITTMANN took over BATTENFELD Kunststoffmaschinen GmbH with its headquarters and production facility in Kottingbrunn (Lower Austria). WITTMANN BATTENFELD is a leading manufacturer of injection molding machinery and equipment for the plastics industry. The company is present in about 60 countries with its own sales and service companies as well as representative offices, thus offering optimal support to its customers in all matters concerning injection molding technology.
The WITTMANN group is successfully represented in Spain by the sales representation WITTMANN BATTENFELD Spain in La Pobla de Claramunt, Barcelona.
