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.

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.

Research

Taking the laser to the workpiece: mobile laser material processing

LZH | So far, the on-site welding, cutting or material removal of large and heavy components was only possible within narrow limits. The Laser Zentrum Hannover e.V. (LZH) and the SET Ltd. have now further developed a new mobile laser processing system to a prototype.

Research

Intelligent tire: Micro production technology meets rubber

IMPT | Novel sensor concepts are supposed to facilitate strain and temperature measurement in future vehicle tires. In cooperation with Continental Reifen GmbH, IMPT is developing production concepts to implement micro components into rubber, which is a quite unusual substrate material.

Research

3D cameras evaluate ergonomics of assembly workstations

IPH/IFA | Awkward bending, lifting heavy items, working overhead: Such movements may cause permanent health problems. As a preventive measure, researchers of IPH and IFA developed an ergonomics assessment tool for assembly workplaces: 3D cameras capture unhealthy movements automatically.

Research

Underactuation: More flexibility through passive structures

match | Passivity pays off – also in robotics. Researchers of the Institute of Assembly Technology (match) are currently developing systems with passive joints: Compared to conventional parallel robots, the advantages are higher flexibility, lower weight, reduced costs and easy reconfigurability.

Research

Communication module stores and processes production data

ITA | Researchers from Hanover have developed a communication module which is able to store and process component-relevant data and communicate it to its environment. The autonomous system is supplied by a tiny solar cell. Its overall size is only a quarter the size of a sugar cube.

Research

Web page explains production planning and control

IFA | With the Hanoverian Supply Chain Model, the Institute of Production Systems and Logistics (IFA) has developed a model which links the tasks of production planning and control with logistic actuating variables, control variables and objectives. The model is freely available on a web page for everybody.

Research

Longer lifetime for tool steels by cryogenic treatment

IW | Up to now, tool steels have been hardened by heat treatment. However, deep-freezing could improve wear resistance even more. For this reason, researchers at the Institute of Materials Science (IW) are investigating a method called cryogenic treatment, i.e. deep-freezing of steel using liquid nitrogen.

Research

Repairing FRP components instead of exchanging them

LZH | Fiber reinforced plastics (FRP) can be used to replace steel sheets, and thus lower the weight of automobiles and aircrafts. However, repairs are often expensive. The Laser Zentrum Hannover e.V. (LZH) is working on making repairs less expensive and more efficient.
