Wittmann Battenfeld: Focus on cost-efficiency and energy-efficiency at the Equiplast fair

At the Equiplast in Barcelona, an international exhibition fort he plastics and rubber industry, which will be held from November 14th to 18th, the Wittmann group will show high tech injection molding technology and processes as
well as their current, modern automation and peripheral equipment in order to presents itself as a competent partner for the plastics industry.

Spain is an important market for the whole,Wittmann group, thus for their injection moulding machinery, automation and peripheral equipment. Accordingly, the company's presentation of products and applications at the Equiplast fair is quite extensive. The main ideas which Wittmann Battenfeld aims to communicate to trade visitors in Barcelona by its demonstration of highly efficient machines are cost-efficiency and energy-efficiency, together with top quality in finished parts for a high customer benefit.

New machines in the EcoPower and in the MacroPower line
In Barcelona Wittmann Battenfeld will show their new MacroPower 650 and the new EcoPower 300. Both machines are an extension of the successful machine lines of the PowerSeries - down to a smaller size in the case of the large MacroPower machine, and up to a higher clamping force range for the all-electric EcoPower machine. As a result, the MacroPower is now available with clamping forces ranging from 650 to 1.000t and the EcoPower from 55 to 300t. According to the manufacturer, the modular, compact design, energy-efficiency, an open structure for quick mold change and high precision are the most important features of the PowerSeries.

At the Equiplast, a pipe fitting with a part weight of 130g will be produced from PP on an EcoPower 300 with a mold supplied by the IFW group. The cycle time including robot operation is only 30 seconds, by using the mold-maker's special XCS cooling system, 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. The 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.
The Inline thermography is a process developed in cooperation with the SKZ (Das Kunststoff-Zentrum in Würzburg, Germany) which is worldwide exclusively marketed and distributed by Wittmann. On the exhibition, 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 Wittmann "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
The energy-saving fleet from the Austrian manufacturer will be completed with an HM ServoPower machine with a clamping force of 110t. This hydraulic machine with servo drive yields a reduction in energy consumption by more than 30% compared to a modern hydraulic standard machine, claims Wittmann Battenfeld. Combined with a moderate pricing this machine´s average payback period shall be about two years only. 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 already 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 the "BFMOLD" 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 Wittmann W818 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 should enable 100% detection of surface defects independent of the presence of a human observer.

About the Wittmann group
The Wittmann group based in Vienna, Austria is a leading manufacturers of robots and peripheral equipment for the plastics industry. The 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, Austria. Wittmann Battenfeld is a 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.

The Wittmann group is present in Spain by his sales representation Wittmann Battenfeld Spain in La Pobla de Claramunt, close to Barcelona, and four other sales offices spread over the country.
