machinery 29 www.smart-molding.com tended range of service-relevant ma - chine parameters and a GRAVIMAX G14 gravimetric blender. The automa - tion system, using a PRIMUS 26T robot from WITTMANN, is implemented via an Easy Cell developed and manufac - tured by WITTMANN BATTENFELD Deutschland in Nuremberg. The Easy Cell mounted on castors requires no safety gate and thus takes up only a minimal amount of space beside the injection molding machine. In spite of its compact design, customers receive the complete range of CE-compliant safety features. On the SmartPlus 180/750 a hub- cap for lawn mowers will be manufac - tured from PP, using a mold supplied by Uralan, Germany. In the interest of sustainable manufacturing, the part will be produced from a mixture of virgin material with regrind. The HiQ Flow® software will be used to en - sure adequate parts quality. This is a material viscosity-related injection control system to compensate the effects of temperature and batch fluctuations on the viscosity of the material. Medical application on EcoPower 55 production cell With the production of a hose clamp for medical technology in an 8-cavity mold supplied by WILAmed, Germany, WITTMANN BATTENFELD will demon - strate its digitization expertise. The machine to be used is an all-electric EcoPower 55/350, equipped with the software packages HiQ Flow® for com - pensating viscosity fluctuations, HiQ Melt for material quality monitoring and HiQ Metering for active closing of the check valve. Equipment integrated in the ma - chine’s UNILOG B8 control system via WITTMANN 4.0 will include a WITTMANN W918 robot, an ATON plus H30 segmented wheel dryer and three temperature controllers from the TEMPRO plus D series, as well as the TEMI+ MES system. The electronic mold data sheet will also be used by UNILOG B8. It enables the produc - tion cell, integrated via a WITTMANN 4.0 router, to check whether the connected auxiliaries are sufficient for the selected product data set, or whether additional equipment is needed. In this application, too, the automation will be installed by way of an Easy Cell from WITTMANN BATTENFELD Germany. LSR application on MicroPower 15/10H/10H COMBIMOULD WITTMANN BATTENFELD will show its expertise in the area of LSR pro - cessing as well as injection mold - ing of micro parts at the Fakuma by manufacturing a support ring with a silicone membrane made of PC and LSR on a MicroPower 15/10H/10H COMBIMOULD. This multi-component version of the MicroPower comes equipped with two injection units in horizontal configura - tion and a rotary disc. The machine is laid out for clean-room injection molding. The rotary disc is completely encapsulated. All connections for heat - ing aggregates, temperature sensors, water tempering, core pull pneumat - ics and sensors, as well as the blow- off valve, are mounted on the rotary disc. The connections to the mold have thus been kept short to enhance the machine’s user friendliness. As in the standard machine, the injection units of the multi-component MicroPower also take the form of two-step screw- and-plunger aggregates with a shot vol - ume of 4 cm³, which enable processing of thermally homogeneous melt with minimal flow paths to achieve excel - lent parts quality. The materials used to make the sup - port ring presented are polycarbonate (Macrolon) from Covestro and a self- adhesive LSR (Silopren) supplied by Momentive. The mold has been con - structed in cooperation with Nexus. The LSR dosing unit comes from Nexus and is equipped with a new Servomix dosing system including an OPC-UA interface (Euromap 82.3). The WITTMANN Group is a globally leading manufacturer of injection molding ma - chines, robots and auxiliary equipment for processing a great variety of plasticizable materials – both plastic and non-plastic. The group of companies has its headquarters in Vienna, Austria and consists of two main divisions: WITTMANN BATTENFELD and WITTMANN. SmartPlus 60
