Networked at all Levels
Wittmann Battenfeld at the Fakuma 2018
Wittmann Battenfeld GmbH of Kottingbrunn, Austria, will present its new VPower series and otherwise emphasizing digital monitoring and assistance systems, as well as applications from multi-component injection molding. In hourly presentations, visitors will be treated to the topics integration, HiQ assistance systems, and CMS (Condition Monitoring System) – a machine-state monitoring system.
Highlighted for the fair will be the premiere of the new vertical VPower machine featuring high energy efficiency, compactness, and user friendliness. At the Fakuma, a VPower 160/750 will be exhibited as the first representative of the series (Fig. 11). With it, the company’s vertical machine series is also being shifted to the PowerSeries design. The machine is equipped with an openly accessible roundtable (1600 mm diameter) that enables simple transport of insert parts and removal of finished parts. The roundtable comes with a servo-electric drive and is configured for short turn times. The absence of a center tie bar enables central medium supply through the rotary table from below, or the installation of a compact rotary distributor. The plasticizing unit can be switched from vertical to horizontal (and vice-versa) even after commissioning.
With the introduction of new models, the fast-running fully electric EcoPower Xpress machine series has been expanded in the lower locking force segment. During the fair, the smallest machine in the series will produce labeled PP covers by an IML process in a four-fold mold in a cycle time of approx. 3 s. The machine is equipped with the company’s own Condition Monitoring System (CMS) that enables continuous condition monitoring of the most important parameters.
Two exhibits will be dedicated to multi-component technology. A teachbox housing for the R9 Wittmann robot control will be produced from ABS and TPU on a SmartPower 240/750H/210S servo-hydraulic machine in a single cavity mold. The preforms are then shifted to a second cavity for encapsulating with the second component. Then a QR code is printed on the surface by an inkjet printer that makes the part including its production data traceable.
The second exhibit involves a sensor part for a medical measuring device in microformat. The spherical-shaped, filmy TPE membrane in the molded part serves to measure a specific pressure within the measuring device. Both components are processed under cleanroom conditions. The MicroPower 15/10H/10H is especially configured for producing 2C mini-parts. Moreover, together with a Wittmann W8VS4 Scara robot adapted for the machine, a camera system integrated into the machine monitors part quality fully automatically.
Machine and periphery networking by "Wittmann 4.0" will be demonstrated on an EcoPower 90/350. This enables robots, tempering devices (Tempro), gravimetric dosing equipment (Gravimax), dryers (Drymax), and throughput regulators (Flowcon) to be integrated into the Unilog B8 machine control. Quality data from machine and periphery can be read out for documentation. For servicing, the Wittmann 4.0 Router enables secure access online to all data modules of a production cell via a single IP address (Single Point Entry). The electronic data sheet represents an innovation by which all devices in a production cell can be configured according to a selected mold data record. Via the "Plug & Produce" mode, the production cell can be ready to produce on short order.
At the same time, the machine is equipped with a HiQ Flow, HiQ Melt, and HiQ Metering software package to demonstrate the function of these assistance systems. With HiQ Flow, temperature and charge variations can be compensated by viscosity-oriented injection regulation, while HiQ Melt enables direct monitoring of material quality via the energy consumed by plasticizing. Via HiQ metering, shot weight reproducibility is increased by actively closing the non-return valve.
