Fakuma Preview 58 Global Plastics rePort 2015 Plasticstoday.com mobility and associated flexibility, the main advantage of this automation is the possibility of direct, autonomous coop- eration between human and robot. The robot will hand the finished, individu- alized 2D and 3D scissors to Fakuma visitors. The Arburg ALS host computer sys- tem seamlessly documents all relevant process parameters and forwards these to a web server. A web page displaying process data can be opened via a unique code using mobile devices. Each indi- vidual part can be seamlessly tracked in this way. The company also plans to present physical foaming of thermoplastics for automotive applications. The Profoam lightweight construction process has been researched and developed with the Institute for Plastics Processing. An electric two-component All- rounder 470 A with a clamping force of 1,000 kN, a size 170 injection unit and a second size 30 injection unit in an L-arrangement will manufacture buttons for car interiors from liquid silicone rub- ber. Another 470 A molder will be pro- ducing y connectors for an infusion ther- apy device using an eight-cavity mold from Männer. The cycle time is around 15 seconds. The highlight of this appli- cation is side injection through a needle- type shut-off nozzle and demolding from three sides of the PMMA molded parts, each weighing 1.1 grams. Hekuma features modularity Manufacturer of high-performance automation systems Hekuma (Eching, Germany) will demonstrate how modu- larity principles can be adapted to the development of individually customized systems. In development since 2013, the newly developed HEKUflex concept will be presented for the first time at Fakuma at booth 7305 in hall A7. The benefits of standardization with HEKUflex are apparent throughout the entire engineering process, says the com- pany. Identical modules are used to a large extent, allowing manufacturers and operators to achieve high repetition rates and a reduction in commissioning and training. Unlike custom machine set ups, which can be laborious, the individual modules only need to be configured, as they work mostly independently based on standard software. The flexible architecture enables sys- tems to be easily upgraded or downsized to meet varying production needs. Müller introduces IML automation Swiss injection mold and in-mold label- ing (IML) automation specialist H. Mül- ler-Fabrique de Moules S.A. (Contey) will present its new six-axis industrial robot at Fakuma 2015 in hall A4, booth 4105. The Flexstar system performs espe- cially well in low-volume to mid-size runs, where frequent changes in SKUs, labels and format are required. It is equally well suited for use in product development, in pilot tests, market test phases and zero series production for fill line validation, for example. Cups and lids in all common shapes and sizes can be decorated in a reliable, trouble-free manner. Depending on whether the products are gated from the inside or outside, labels can be inserted in the cavity and finished parts removed from either the stationary or moveable half of the mold. The system has a surprisingly small footprint and a modular architecture. The robot is capable of performing minor assembly steps or inserting auxil- iary parts, and the unit can be equipped with a vision control system, stacker or packaging module, as needed. Up to four cavity applications can be accommodated. The robot has been con- figured for dynamic insertion: Before the mold is completely open, the gripping arm advances into the machine. The labels are inserted in the mold and the finished parts are removed and stacked. Subsequently, new labels are picked up from the magazines and the gripping arm returns to its waiting position. To date, the robot has been configured for injection molding machines up to approximately 2500 kN; additional versions for larger injection molding machines are under development. Ettlinger shows array of melt filters Ettlinger Kunststoffmaschinen (Königs- brunn, Germany) will show its com- plete range of high-performance melt filters, designed for continuous pro- cessing of any kind of feedstock from virgin material to heavily contaminated recycled plastic, at Fakuma 2015. The company is exhibiting at booth 6209 in hall A6. The recently introduced ECO melt filters were developed for film and sheet extrusion. Rated for a maximum con- taminant level of 1.5% by weight, they enable cross-linked and high-molecular melt fractions to be efficiently removed when processing virgin material, along with any gels or partial impurities. ECO melt filters come in two sizes: The ECO 200 for throughputs up to 1000 kg/h and the ECO 250, which can process up to 3000 kg/h. The filter can also be sup- plied as a PET version for filtering easy flow melts such as polyester. The ERF melt filters, proven in more than 225 installations, are espe- cially effective for heavily contaminated feedstock. Reliable, pressure-stable, con- tinuous processing is guaranteed with up to 18% contamination by weight. The ERF500 is the largest and achieves throughputs of up to 6 tons per hour. ERF filters are available in three sizes: In addition to the ERF 500, the compa- ny offers the ERF 250 with a maximum throughput of 3 tons per hour and ERF 200, which can process up to 1 ton per hour. A key feature common to both filter series is their longevity. Whereas conven- tional piston screen changers can require many screen changes per day, the ECO and ERF models achieve a service life of several weeks with no disruptions to production. The central component of both series is a rotating, cylindrical filter screen with millions of conical holes. Ettlinger will showcase its recently introduced ECO melt filters at Fakuma 2015.
