HANNOVER MESSE 2020,
20 - 24 April
Our laser beam cutting topics focus on the investigation of process developments in the field of laser fusion cuttings. The scientists especially attach attention to the improvement of the cutting quality in the case of solid-state laser. Another main point is to optimize the cutting of electrical steel sheets without losing any magnetic properties.
Furthermore novel cutting procedures, e.g. Remote laser cutting, have to be qualified in order to be integrated into production processes.
For these tasks we have at our disposal all common lasers with different wave lengths, power and beam qualities, combined with highly dynamic 2D and 3D cutting machines. Apart from commercial processing optics we develop special solutions on customers` request such as scanning systems for Remote processings. Furthermore we offer comprehensive methods to characterize the processing results, such as roughness measurements at the cutting edge or the detection of magnetic reversal losses at laser cut electrical steel sheets.
(Dresden, March 18, 2019) Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a joining gun that creates a connection between metal and thermoplastic materials within seconds. This gun is of a modular de-sign and can easily be integrated into the production process, for example by mounting on a robot arm in place of a spot welding gun. The advantages of the joining gun will be presented at the Hannover¬messe 2019, Fraunhofer joint booth (hall 6, booth A30).
(Dresden, March 18, 2019) Together with the company Erich Utsch AG scientists of the Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS Dresden have developed a process for the protection of license plates for motor vehicles. The development is triggered by the fact that many of the established product protection concepts are either too inflexible or uneconomical. The results will be presented at the Hannovermesse 2019, Fraunhofer joint booth (hall 6, booth A30).
