“As-built“ scan enables creation of digital twins

IFW | Creating material flow simulations for bottleneck analyses, factory planning or stock analyses requires a lot of initial effort. IFW is currently developing a procedure that scans the production facilities and then creates a digital simulation model in an automated process.

Research

Ultra-fast assembly by consistent kinematics

ITA | To enable the production of larger quantities of smaller chips, ITA is investigating an ultra-fast assembly technology for electronic components. The researchers are using laser technology for the contactless transfer of bare chips onto a substrate.

Research

Automated 3D printing for highly individual production

IPH | By automating process steps, additive manufacturing can be integrated into industrial value chains. The Institut für Integrierte Produktion Hannover (IPH) gGmbH has been designing a process chain linking 3d printers and mounting stations automatically.

Research

Printing hearing aids with customized hardness zones

LZH | Individually shaped earmolds are already commercially available, but do not take into account the varying tissue hardness in the ear canal. In a joint project on multi-material printing, the Laser Zentrum Hannover e.V. works on hearing aids with customized hardness zones.

Research

Process-reliable definition of subsurface properties

IW/IFW | The quality of a component is dependent on its subsurface properties. However, their process-reliable definition can only be reached by component-specific production control. By the use of soft sensors and a learning process model, the production system shall modify process parameters autonomously.

Research

Understanding digitalisation online

IFW | What does digitalisation mean and how can new work tasks be understood? There are many open questions, but employees often find it difficult to match job and continuing education. To find a remedy, researchers from Hannover are presently developing an online-based learning platform.

Lightweight design: thermomechanical precision forging

IFUM | IFUM uses thermomechanical process control to produce thin-walled gear rims. Within the scope of the joint research project “Lightweight Forging”, such gear rims are combined to weight- and efficiency-optimized gear wheels used for gearboxes in cars.

Research

The best of two materials: light and strong at the same time

IPH | Hybrid structures used in automotive lightweight design are composed of different materials as well as of bulk and sheet metal parts. Hybrid compound forging is a method to create a material bond between a steel sheet and a bulk aluminium part already during the forming process.

Research

Drilling and milling: Robot lets chips fly

IFW | Conventional industrial robots are not suitable for use in machining processes. However, most recent research results present mechanisms that increase the positioning accuracy and stiffness of robots, making them usable in metal machining processes. Research at IFW increased the stiffness tenfold.

Research

Benefits from clever site selection in metropolitan areas

IFA | High potential for work and employment, strong infrastructure and dense production networks: The advantages in metropolitan areas. Researchers are currently developing a trendsetting planning approach that allows companies to identify and use them for their own benefit.

Research

Innovative method for the production of grinding wheels

IMPT | Micro structures have a lot of advantages, but their creation is a complex process. This has motivated IMPT and IFW to develop a method for the manufacture of high-precision micro grinding tools with a flexible bond matrix: one process for two types of grinding wheels.

Research

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.

Research

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.

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.

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.
