Careful disassembly increases sustainability of products

match | Above all, high-quality goods shall be disassembled at the end of their lifetime, either to get them repaired or to reuse their components. This can be achieved by component-friendly disassembly processes, increasing sustainable reuse of products considerably.

Experiments for simulating wet welding under water

IW | Repair work carried out at offshore wind turbines poses new challenges: Researchers of the Institute of Materials Science (IW) generate data to make the finite element method also usable for the simulation of wet underwater welding.

Dr.-Ing. Stefan Kaierle new Executive Director of the LZH

LZH | On April 16th, 2018, Dr.-Ing. Stefan Kaierle takes over the scientific and technical management of the Laser Zentrum Hannover e.V. (LZH) together with Dr. Dietmar Kracht. He succeeds Prof. Dr.-Ing. Ludger Overmeyer, who takes over the Chairmanship of the Scientific Directorate from Prof. Dr. Wolfgang Ertmer.

Research

Printing and forming of optical waveguides

ITA | In future, printed optical waveguides will be used for multimedia transmission in cars and aeroplanes. The requirements are correspondingly large bandwidths and three-dimensional forming. DFG approves another three years of research of OPTAVER research group, in which scientists from ITA and LZH work together with fellows from Nuremberg, Erlangen and Dresden.

New forming simulator: Gleeble 3800 launched at IFUM

IFUM | For a more comprehensive determination of material properties: At the Institute of Forming Technology and Machines (IFUM), the Gleeble system has been installed at the Department Material Characterisation and Simulation. It is even suitable for simulating bulk metal forming processes.

Forschung

Three-dimensional factory layout with UAV scan

IPH | In future, factory layouts can be created a lot faster and at a more favourable price: On its flight across a factory, a UAV shall scan all the installations, storage areas and machines and create a three-dimensional model. This is one of the research topics of the Institut für Integrierte Produktion Hannover (IPH) gGmbH.

Research

Exact temperature measurement during hot stamping

IFUM/IMPT | Precise temperature control is a decisive factor during hot stamping: Only if the component part is cooled down fast enough, it is hardened sufficiently. For direct temperature measurement in the tool, researchers at IFUM and IMPT developed a thin-film sensor.

Collaborative Research Centre presents hybrid components

CRC 1153 | Experts from the Collaborative Research Centre “Tailored Forming“ are developing new methods for the production of hybrid components, combining the advantages of different materials. Around forty technical exhibits will be presented at Hannover Messe taking place from 23 to 27 April.

Hannover Messe 2018: factory planning and additive manufacturing

IPH/LZH | The Institut für Integrierte Produktion Hannover (IPH) gGmbH presents new methods for an optimal factory planning. The Laser Zentrum Hannover e.V. (LZH) will be presenting a process chain for additive manufacturing, and the safe deflagration of unexploded bombs using laser technology.

Professorship in Lüneburg: Matthias Schmidt leaves IFA

IFA | The Institute of Production Systems and Logistics (IFA) had to say goodbye to one of the leading heads: Professor Dr Matthias Schmidt is leaving the institute after more than twelve years to take up a professorship at Leuphana Universität in Lüneburg.

Research

Producing engines more efficiently with laser technology

LZH | Aluminum engines save weight and fuel. A steel layer protects the inner surfaces of the cylinder from wear. For the layer to stick firmly, the surface must be rough. Laser-based roughening is an alternative to conventional processes such as corundum blasting or machining.

Research

More durable implants by coatings with capillary texture

IW | Abrasive wear in joint protheses can induce inflammatory reactions and bone resorption. Researchers want to improve the frictional properties using human synovial fluid. The fluid’s distribution in the joints is improved when using a ceramic coating with capillary texture.

Research

Automated tooth polishing thanks to intelligent machinery

IFW | In the past, the polishing of dental products has been a manual machining process. The aim of researchers at IFW is to develop and implement an automated polishing process on a machine tool, thus creating an adaptive system which improves with every polishing process.

Professorship for former LZH Head of Group

LZH | Dr.-Ing. André Springer becomes a professor: At the University of Applied Sciences Ostwestfalen-Lippe he will research and teach in the field of additive manufacturing. He had been working in the Materials and Processes Department at the Laser Zentrum Hannover e.V. (LZH) for 10 years.
