Vertically and Horizontally Cross-Linked
Various applications on all-electric and hydraulic molding machines enable Wittmann Battenfeld GmbH & Co. KG of Meinerzhagen, Germany, to place different technical and industrial focuses. Among other things, multi-component and internal gas injection molding take center stage. All machines reflect complete integration.
The new EcoPower Xpress is a fast running, all-electric machine conceived mainly to meet the requirements of the packaging industry and/or thin-wall applications. Its highly dynamic drive axes for injection, closing, and opening are designed for rapid movements and high control accuracy. The use of highly dynamic servo drives also ensures a high level of energy efficiency. According to the manufacturer, the machine will be available in the clamping forces 4000 and 5000 kN on the market from autumn onwards. Wittmann will demonstrate the functionality of the smaller model using an EcoPower Xpress 400/3300+ to produce HDPE bottle caps in 2.7 s cycle time in a 96-fold mold from the French company Plastisud SAS. The caps are cooled by a Capcooler from Eisbär Trockentechnik GmbH and deposited in boxes.
Multi-component technology is represented with three exhibits. A 2-component application in which one component is thermoplastic and the other is liquid silicone will be presented on a SmartPower 120/525H/130L. The parts will be molded in a 4+4-fold mold from the Italian company Linea Stampi, and removed by a Wittmann W831 robot with a new R9 control and deposited on a conveyor belt. A SmartPower 80/210H/210S/210V will demonstrate a 3-component application. With a 6-fold mold from geobra Brandstätter, PPT, POM and PA will be combined to produce a Playmobil chimpanzee. A third application involves producing a 2-component pickup cartridge for a vinyl record player. The finished electrically conductive parts made from PC and electrically conductive PC will be produced by a single-cavity mold from Ortofon in Denmark on a Micro Power 15/10H/10H equipped with two parallel injection units and a turntable. A Wittmann W8VS4 Scara robot handles the removal and deposition of the parts. In addition, a camera system integrated in the machine provides for all-automatic quality control of the parts.
All of these exhibits will realize and demonstrate machine and periphery networking by Wittmann 4.0. For the first time, Aton dryers can be integrated in the Unilog B8 machine control in addition to the integration of robots, Tempro temperature control, Gravimax gravimetric dosing devices, and Flowcon flow controllers.
In particular, integration in the Unilog B8 machine control via Wittmann 4.0 will be demonstrated using a machine from the all-electric EcoPower series with an insider cell. On this machine, an EcoPower 160/750 with 1600 kN clamping force, a clothes hanger will be shown that comes from a single cavity mold from Haidlmair GmbH which utilizes the Airmould internal gas pressure technique. The Airmould interface is also integrated in the Unilog B8 control. The unit for generating pressure and nitrogen was developed and produced by Wittmann Battenfeld. The parts are removed by a Wittmann W818 robot and deposited on the conveyor belt integrated in the cell.
The introduction of the MES system from MPDV Mikrolab GmbH, Wittmann’s new partner for MES, will be used to illustrate the networking of injection molding machines, i. e., inclusion in Industry 4.0. The highlight will be the integration of the SmartMonitoring module on every B8 display screen. With it, the status of all the injection molding machines in a network can be checked from any machine. The integration of an injection molding machine via the Euromap 77/83 protocol based on OPC/UA that will soon be available will be shown. Euromap plans to release their new EM 77/83 in February 2018.
In their trade show, Wittmann Battenfeld is presenting the functionality of their CMS (Condition Monitoring System) for machine status monitoring. In the course of the CMS, important machine status data are measured by sensors, evaluated in machine control, and made available via MES for maintenance planning by the company.
