Three New Models in the SmartPower Machine Series
Wittmann Battenfeld GmbH, Kottingbrunn, Austria, is following on from its participation at the Fakuma 2014. Last year the company presented the SmartPower machine series for the first time with mold clamping forces from 50 to 1,200 kN; this year it is completing the range with three models in the sizes 1,800, 2,400 and 3,500 kN. The machines of the SmartPower series have as standard a highly efficient servo hydraulic drive and – as already known from the all-electric EcoPower series – use the available braking energy via KERS (Kinetic Energy Recovery System) for the screw barrel heating, so achieving a high degree of energy efficiency.
Production of a thermoplastic continuous fiber-reinforced part from an organic sheet will be demonstrated on a SmartPower 350/2250 with a mold clamping force of 3,500 kN using a single-cavity mold from Georg Kaufmann Formenbau AG, Busslingen, Switzerland (Fig.). The mold is equipped with a hot runner with needle valve, a slider unit for forming the organic sheet in the mold and a punch for punching out an opening in the organic sheet. The manufacturing cell is completed with a Wittmann Battenfeld robot system, a station for preparation of the cut organic sheets, a heating station for heating up the organic sheet and a multifunction handling unit with needle gripper for picking up the heated organic sheet and suction pads for removing the finished parts.
Medical technology is an industry with highest demands on precision and freedom from contamination. For trade visitors from this industry, Wittmann Battenfeld will be presenting a specially configured EcoPower 110/350 qualified for clean room operation. In this version special attention was paid to both the cleanliness of the mold interior and to minimizing the machine emissions to the environment, i.e., into a clean room.
For this application the machine has been equipped with the EcoPower "Clean Package" including i.a. a water cooling system for the whole machine with closed-center cooling circuit, nickel-plated platens, the use of food grade lubricants and a special cleaning agent and disinfectant-resistant paint finish. Furthermore, the machine that in Friedrichshafen will be used to produce contact lens trays of PP is equipped with a laminar flow box and a deflector to separate good and bad parts, as well as an encapsulated clean room belt conveyor (manufacturer: Max Petek Reinraumtechnik, Radolfzell, Germany) installed under the clamping unit.
In a specially installed service center, the visitors can also find out about "SmartMonitoring". The new process data acquisition software allows access to a universal database. Here Wittmann Battenfeld uses the monitoring module from authentig with integrated online overview of the machine park. With this simple interface to the leading MES, users can call up a works overview also via the Unilog B6P machine controller.
In addition, the company will be presenting "Wittmann 4.0" as an important integration module. Via the B6P machine controller both machines and interfaced robots and peripheral devices can be linked and operated via a uniform Windows interface. All the phases of the production process, starting with the material feed, can thus be perfectly synchronized. All settings, automation process and recipes are stored centrally in the mold catalog and can be uploaded to the right equipment in the event of a mold change. In addition, all error and status messages are collected centrally.
