Die Epson Deutschland GmbH startet im April in ihr neues Geschäftsjahr 2023/2024. Trotz der gesellschaftlichen und politischen Einschnitte im letzten Jahr und der daraus resultierenden Unsicherheit in der Wirtschaft kann das Unternehmen auf eine stabile Entwicklung im noch laufenden Geschäftsjahr verweisen und blickt optimistisch auf das kommende. Basis hierfür ist die konsequent nachhaltige Ausrichtung des Technologiekonzerns und die Realisierung dieser Planungen. Das Ziel zu 100 Prozent mit Ökostrom weltweit in allen Produktionsstätten und Niederlassungen zu arbeiten, wird in 2023 erfüllt. Neue Technologien wie die Dry-Fiber-Technologie (DFT) und Metal Injection Molding (MIM) sind Ergebnisse einer Forschungs- und Entwicklungsarbeit, die den japanischen Konzern in Sachen Nachhaltigkeit zukunftsfähig aufstellen.

100 Prozent Ökostrom weltweit
2023 kann Epson einen wichtigen Meilenstein seiner Umweltvision erfüllen: alle Produktionsstätten und Vertriebsniederlassungen werden weltweit auf Strom aus erneuerbaren Energien umgestellt. Aktuell setzen bereits alle Epson-Standorte in Japan, in Europa und in einzelnen Werken im asiatischen Raum auf Ökostrom.

Umwelttechnologien: Recycling von Kleidung
Die einhundertprozentige Nutzung von Strom aus erneuerbaren Energiequellen ist Teil der Epson Umweltvision 2050. Eine weitere wichtige Säule dieses Programms ist die Entwicklung von Umwelttechnologien. Mit der Dry-Fiber-Technologie arbeitet Epson an einer Recyclingtechnologie, die bereits im Einsatz ist, zukünftig aber noch viel breiter Anwendung finden kann. Basis der Technologie ist die Zerlegung von Ausgangsstoffen in ihre Fasern, die sich dann auf verschiedenen Wegen wieder zusammenführen lassen. Auf dem Markt bereits erhältlich ist das PaperLab, Epsons Papierrecyclingmaschine, die aus altem Büropapier neues herstellt. Mit dieser Technologie lassen sich auch Textilien zerfasern und zu Stoffbahnen (Vlies) wieder zusammenfügen.

New Work in Düsseldorf
2023 wird überdies ein Aufbruchsjahr für die Mitarbeitenden in der Meerbuscher Vertriebszentrale. Nach 20 Jahren geht die Epson Deutschland GmbH wieder zurück nach Düsseldorf. Das Unternehmen hat ab dem Frühjahr 2023 rund 3.000 Quadratmeter im gerade im Bau befindlichen Gebäude TRIGON in Düsseldorf-Heerdt angemietet.

At the recent CAMX 2022 Composites and Advanced Materials Expo in Anaheim, California, The Heat Sealing Module – HSM from Zünd was recognized with an Unsurpassed Innovation Award. The HSM significantly facilitates the processing and handling of dry fiber materials with thermoplastic content. This new tool is Zünd’s answer to a demand in the composites industry for wider-spread use and easier processing of these types of materials.

The American Composites Manufacturing Association, ACMA, proclaimed the Heat Sealing Module – HSM the winner of the ACE Award for Unsurpassed Innovation in the “Manufacturing: Equipment and Tooling” category. This award is presented annually to equipment, tooling, a production aid, or software designed to improve manufacturing production, environmental sustainability, or product quality and performance in composites manufacturing.

During processing, dry fiber materials are prone to fraying along the edges. Using hot air, the HSM seals the fabric along the cut path in advance of the Zünd Power Rotary Tool – PRT cutting it. Because of this sealing process, the cut can then be performed at full speed, in any direction, and produces both higher-quality parts and greater production efficiencies.

The HSM helps create clean, sealed edges when cutting fiber-reinforced thermoplastic composites. It benefits not only the cutting process itself, but other production processes downstream. Cutting this way leaves behind no loose or uncut fibers and maintains a clean cutting surface and uncontaminated production environment. At the same time, it ensures that cut parts maintain their shape, and this increased stability makes them much easier to handle, especially in fully automated production workflows.

The two AZL Partners Conbility GmbH and Fraunhofer IPT, Aachen started their long-term cooperation for the further development and for the commercialization of Fraunhofer´s tape-placement and tape winding systems with in-situ-consolidation by the usage of laser or IR heat sources.

With this cooperation, the company Conbility GmbH makes 25 years of expertise in special machine development of tape placement systems of the Fraunhofer Institute for Production Technology IPT commercially available. Conbility offers two different tape processing systems available in different configurations.

The “PrePro 2D” machine system allows for the automated tailored tape placement of UD laminates and which can be used for subsequent thermoforming or as stiffening structures in injection molding processes. The machine comprises a rotating and translational table which is moved relatively to the applicator station. The table is scalable according to the requirements of customers. Standard table diameters are 1200 mm or 2000 mm. The applicator station can be equipped with a single or with multiple spool applicators. Because of the large process area, a 9 kW IR heater is used for the in-situ-consolidation process.  
Three in one: Three technologies included in one single modular system
Furthermore, the award-winning “PrePro 3D” tape placement and winding applicator is available as modular product with decentral control system (including closed-loop control of energy input into the processing zone) for the “plug-in” implementation in existing robot systems or machine systems by standard interfaces for the communication with the master control system. Conbility provides the single applicator as well as turn-key ready systems including the robot and handling systems.

Unique selling point of the PrePro 3D system is its multifunctional range of usage: it accomplishes laser-assisted thermoplastic tape placement, IR-assisted thermoset prepreg placement and dry fiber placement: Three technologies included in one single modular system.  

During the JEC World in Paris (March 6th – 8th 2018), Conbility GmbH will present its new “VCSEL Tape Placement and Winding Applicator” (Fig. 3), developed in cooperation with Fraunhofer IPT and Philips Photonics at the AZL Composites in Action area (Hall 5A, C55).

VCSEL Laser Systems as heat source for lower investment and process costs
This applicator uses an integrated VCSEL Laser System as heat source which has been developed by Philips Photonics. This tape placement and winding applicator can also be integrated as modular “plug-in” system into industrial jointed-arm and linear gantry robots in variable manufacturing cells. Using the new VCSEL Laser as heat source (VCSEL: Vertical-Cavity Surface Emitting Laser) leads to significant lower investment and process cost in comparison to other laser systems. Furthermore, the VCSEL laser system can accomplish controllable in-process adjustments of the laser-spot geometry as well as the intensity distribution within the spot size during the process (in-process control of laser-spot geometries and intensities) for the first time. The new system with 2 kW laser power and 10 separate emission zones which can be controlled separately will be shown at JEC World in Paris 2018 as new product of Conbility GmbH.
