Wittmann Battenfeld to Showcase Product Highlights at Fakuma 2021
Wittmann Battenfeld will be exhibiting at Fakuma this October at booth 1204 in hall B1, showcasing its product highlights and championing its new digital platform Wittmann Interactive.
Highlight: SmartPlus
The highlight of this year’s presentation by Wittmann Battenfeld is the new SmartPlus. The SmartPlus is a servo-hydraulic machine that stands out with its high level of cost and energy efficiency, as well as repeatability. Thanks to the use of proven technologies and carefully selected options, short delivery times and an excellent price-performance ratio have been made possible for this machine.
A special feature of the SmartPlus is the new B8X control system with system components developed in-house. These enable a higher frequency, shorter response times and a higher repeatability rate for parts, with the same operating comfort as before and the familiar visualisation concept. Of course, the SmartPlus also offers the KERS energy recovery technology originally developed for the EcoPower.
The SmartPlus is currently undergoing practical tests at selected customers. From the fourth quarter of 2021 onwards, the machine is expected to be available in the first series with clamping forces ranging from 60-180-tonnes.
The advantages of the new SmartPlus will be demonstrated on a SmartPlus 180/750. This machine is equipped with the HiQ Flow® application software, the new CMS-Light condition monitoring system to monitor an extended range of service-relevant machine parameters and a GRAVIMAX G14 gravimetric blender. Using a PRIMUS 26T robot from Wittmann, the automation system is implemented via an Easy Cell developed and manufactured 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 moulding machine. Despite its compact design, customers receive the complete range of CE-compliant safety features.
On the SmartPlus 180/750, a hub-cap for lawnmowers will be manufactured from PP, using a mould 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 ensure adequate parts quality. This is a material viscosity-related injection control system to compensate for 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 mould supplied by WILAmed, Germany, Wittmann Battenfeld will demonstrate its digitisation expertise. The machine to be used is an all-electric EcoPower 55/350, equipped with the software packages HiQ Flow® for compensating viscosity fluctuations, HiQ Melt for material quality monitoring and HiQ Metering for active closing of the check valve.
Equipment integrated with the machine’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. UNILOG B8 will also use the electronic mould datasheet. It enables the production 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, 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 processing as well as injection moulding 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 configuration and a rotary disc. The machine is laid out for cleanroom injection moulding. The rotary disc is completely encapsulated. All connections for heating aggregates, temperature sensors, water tempering, core pull pneumatics and sensors, as well as the blow-off valve, are mounted on the rotary disc. The connections to the mould 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 volume of 4 cm³, which enable processing of thermally homogeneous melt with minimal flow paths to achieve excellent parts quality.
The materials used to make the support ring presented are polycarbonate (Macrolon) from Covestro and a self-adhesive LSR (Silopren) supplied by Momentive. The mould has been constructed 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).
IMAGOxt to minimise energy consumption
All machines exhibited at the Wittmann booth will be equipped with the IMAGOxt software, an additional module for the MES TEMI+. IMAGOxt makes it possible to visualise and monitor the energy consumption or energy flow.
IMAGOxt supports the preparation of a detailed energy cost analysis for the machines connected to it. This enables subsequent creation of user-defined KPIs, generation of personalised alarm signals and monitoring of the company’s energetic performance.
AIRMOULD® centre
The latest developments in the area of AIRMOULD® internal gas pressure technology will be presented in a separate AIRMOULD® centre at the booth. Here, interested visitors can gather detailed information about the opportunities this technology has to offer in terms of sustainable parts manufacturing, as well as the advantages of the new pressure control module and the AIRMOULD® Next manual operating device of the next generation.
Wittmann Interactive – streaming from the fair to the technical labs
In addition to the exhibits on display at booth 1204 in hall B1, the Wittmann Group will offer its visitors the opportunity to log in on-site with the technical labs in Kottingbrunn, Meinerzhagen and Nuremberg, using the new media technology Wittmann Interactive, to receive information about further selected exhibits.
Through Wittmann Interactive, Wittmann Battenfeld will present existing technologies such as the CELLMOULD® lightweight technology on a MacroPower 1100/12800. With this machine, a seat carrier for a German sports car model will be manufactured from PP using a single-cavity mould supplied by Frimo, Germany.
Moreover, inline recycling with a SmartPower 60 Ingrinder will be demonstrated at the Meinerzhagen facility. A can with a lid made of PS will be produced using a double 2-cavity mould on this machine.
At the facilities, several new applications will also be shown in addition to familiar technologies:
Injection compression moulding for thinner wall thicknesses
In injection compression moulding (ICM), the melt is injected into a mould that is not completely closed. The actual forming process takes place by way of pressing the melt into the cavity after the mould has been closed. In this way, the mould can be filled under lower pressure, which results in reducing the warpage inside the part.
Wittmann Battenfeld will present this technology in Kottingbrunn using a high-speed EcoPower Xpress 160/1100+. The machine is equipped with a Wittmann robot for fast parts removal. Using a 4-cavity mould supplied by GLAROFORM, Switzerland, a thin-walled cup will be produced within a short cycle time. The highly dynamic drive technology of the high-speed EcoPower Xpress makes it possible in particular to work with the short injection times required for the ICM process.
Saving resources with AIRMOULD® Next internal gas pressure
With AIRMOULD® Next internal gas pressure technology, nitrogen is injected into the mould cavity, which is either partly or completely filled with melt, thus forming an internal cavity structure. In this way, lightweight parts can be produced quickly and simultaneously with good surfaces.
Wittmann Battenfeld developed all necessary system components. The pressure control module and the manual operating device required for use on machines of other brands have been thoroughly revised, with a special emphasis primarily on the compact design of the new units and improvement of user-friendliness and quality monitoring.
The new AIRMOULD® Next internal gas pressure technology will be demonstrated in Meinerzhagen with a SmartPower 120/525. On this machine, a towel holder made of polystyrene will be produced.
Decorated and functionalised surfaces
In a joint project with LEONHARD KURZ, a maker of functional foils and foil feeding equipment, and Syntech Plastics, an IMD technology supplier, Wittmann Battenfeld is continuing to drive the interesting and promising theme of decorated and functionalised surfaces for the automotive industry as well as white goods and other sectors, by supplying appropriate injection moulding technology. To this end, the company is working on a machine concept that incorporates all essential elements for four different decoration processes and will be adjustable to specific applications. The equipment is to be laid out flexibly for IMD with a foil feeding unit, IMD with foil pre-heating, IMD Vario with pre-heating and thermoforming insert moulding. The machine is equipped with the EXPERT-Coining package, which permits parallel mould movements during the injection process.
Via Wittmann Interactive, the partners will present the production of an interior covering for the automotive industry with a functional surface at the Wittmann Battenfeld facility in Nuremberg on a SmartPower 300 production cell with automation and Wittmann 4.0 integration. The finished interior part will be shown to demonstrators at both the Wittmann booth and the booth of LEONHARD KURZ.
Fakuma will take place from 12-16 October 2021 in Friedrichshafen. Visit www.fakuma-messe.de/en/ for more information.
