Seven to see at Fakuma

  • It’s not a K year, which means that Fakuma, the international trade fair for plastics processing, is back in business. And it’s a special year at that: Fakuma celebrates its 25th anniversary in Friedrichshafen, Germany, on Oct. 17 to 21.

    More than 1,700 exhibitors and 40,000 attendees will congregate at the event dedicated to injection molding, extrusion, thermoforming, blowmolding and other plastics processing technologies and ancillary equipment and products.

    There will be a lot to see and experience on the show floor. You can get a head start by flipping through this slide show.

  • Plastics are the materials of the future for optical devices, according to the Institute of Plastics Processing (IKV) in Industry, the Skilled Crafts at RWTH Aachen University, and the Fraunhofer Institutes for Production Technology (IPT) and for Laser Technology (ILT), all of which are based in Aachen, Germany. They will showcase recent developments in the injection molding of optical components at the shared Kunststoffland NRW stand (4404) in hall B4.

    IKV and the IPT and ILT Fraunhofer Institutes will present new developments in optical systems design and the construction of tools and mold inserts. Injection and compression molded optics, continuously manufactured optical film and innovative optical materials and applications will be on display. A special focus will be the production of micro-structured lenses made from liquid silicone rubber (LSR). Because of its temperature and UV stability, this innovative material is particularly interesting for LEDs. The flexibility and elasticity of LSR also open up innovative design concepts, according to the research institutes.

  • If you were at K last year, you might have spotted Arburg’s hybrid Allrounder 1120 H (pictured), which made its global debut at the Düsseldorf show. Since then, the machine has been successfully used by pilot customers and it can now be ordered worldwide.

    The next step in the future-oriented new Arburg design and Gestica control system is the hybrid Allrounder 920 H with a clamping force of 5,000 kN, which will be featured at stand 3101 in hall A3.

    At the show, the Allrounder 1120 H will form part of an innovative turnkey solution, producing the familiar folding step stool in the Arburg design in a cycle time of 60 seconds. The eight individual parts will be handled by a Multilift V 40 linear robotic system and assembled ready for use by means of a six-axis robot and assembly station.

    The new Gestica control system has a high-resolution screen and uses industrial multi-touch technology to mimic the look and feel of smart mobile devices.

  • The newly established Römheld subsidiary Römheld Rivi GmbH (Laubach, Germany) makes its debut in front of a broad audience at Fakuma. Römheld Rivi aggregates the parent company’s expertise in magnetic quick clamping systems for plastics and rubber processing. At Fakuma, the focus will be on systems that are suitable for high-temperature processes. The company is holding court at stand 1223 in hall A1.

    M-TECS magnetic clamping plates can be used in working temperatures up to 240° C, making them suitable for processing rubber and high-tech thermoplastics such as polyetheretherketone (PEEK) or polyphenylene sulphone (PPSU). Römheld Rivi claims to be the only company in the world with magnetic clamping plates that can be used at such elevated temperatures.

    Magnetic clamping technology has a tremendous benefit when working with PEEK polymer for medical, electronic and aerospace applications, for example. In continuous use, the high-performance plastic can be used at temperatures up to 260° C, and the smelting process only starts at approximately 335° C, according to Römheld Rivi.

  • Wake up and don’t smell the coffee at the Netstal (Näfels, Switzerland) stand, where the company will be manufacturing aroma-protected three-layer coffee capsules using a precision co-injection process. An all-electric, two-component Elion injection molding machine delivering 1,200 kN of clamping force will enable IML-decorated plastic capsules to be efficiently manufactured with a reliable barrier effect.

    Unveiled for the first time at Fakuma, the application will see an all-electric Elion 1200 produce the capsules on a VNC-integrated Plasdan injection unit equipped with a four-cavity Fostag test mold. The overall cycle time will be around 4.9 seconds. An automated Beck handling system automatically places Verstraete IML in-mold labels into the mold and removes the decorated capsules following  the injection process. Finished parts are then stacked and an IMD Vista optical inspection system integrated within the removal robot checks the position and thickness of the EVOH barrier. Finally, the Nespresso-compatible capsules are stored in bulk in a container.

    Find the company on stand 7303 in hall A7.

  • Injection molding machine maker Engel (Schwertberg, Austria) introduced the viper series of linear robots in 2009. At this year’s Fakuma, it will present the viper 20 speed robot, which improves performance by more than 30% compared with the viper 20. The viper 20 speed is better able to meet the requirements of the packaging and medical sectors for small to mid-size machines, according to Engel.

    At stand 5204 in hall A5, you can watch the viper 20 speed robot work in tandem with an Engel multi-axis robot to remove cups from a conveyor belt and stack them. The viper 20 speed achieves removal times well under one second, according to Engel.

    Typical applications include the production of food containers or sample cups for medical analysis, where top-entry robots tend to be highly flexible.

  • A new plasticizing system for compounds with high levels of glass-fiber reinforcement provides wear resistance, high throughput and gentle mixing. The Exaloy product from Nordson Corp. (Neckarsulm, Germany) enables injection molders to meet the requirements of metal replacement and other high-strength applications while enhancing productivity and part quality. The company will showcase the Exaloy High Glass-filled Polymer System at stand 6109 in hall A6.

    Components of the Xaloy system include:

    The Xaloy screw, which is designed with a wave-style root geometry to enhance distributive and dispersive mixing and provide continually varying, localized high- and low-pressure areas to achieve complete melt homogenization with low shear;Xaloy X-8000 screw encapsulation, a nickel-based alloy with high tungsten carbide content that provides twice the abrasive and corrosion wear life than standard high-velocity oxy-fuel applied coatings;an Xaloy X-8000 barrel inlay—a liner that combines a nickel-based alloy with tungsten carbide to impart abrasion and corrosion resistance; andan application-specific valve designed to accommodate the viscosity and flow properties of highly filled compounds.
  • As is customary, KraussMaffei (Munich) will present a number of leading-edge technologies involving injection molding and reaction process machinery at stand 7308 in hall 7. Premiering at this year’s show is the LRX 100, part of a new generation of small linear robots that feature a new design with a decentralized control cabinet and freestanding X-axis. They offer flexibility in processes such as simple retrofitting of sensors or expansion of media circuits. Rack-and-pinion drives are used in lieu of toothed belts to achieve fast, high-precision movements in all axes.
