Welcome to the website of the research group - Regeneration of moulding tools for mass-suitable lightweight design. Our research group of scientists from the Institute of Production Engineering and Machine Tools (IFW) of the Leibniz Universität Hannover and scientists from Institute of Joining and Welding Technology of the Technischen Universität Braunschweig.
Beside the collaborative research project, the group creates a new moulding tool centrum in Hanover/Brunswick. Issues from the industry concerning die castings, injection mouldings and forming tools will be discussed in specialist conferences and thematic working groups. Furthermore, new research projects and ideas for industrial applications will be developed together.
Resource-efficient mobility requires the reduction of component weight of vehicles. To achieve this goal, the automotive and aerospace industries are increasingly using light metals and plastics, which are processed by injection and die casting processes. Due to the increased production demand, the used moulding tools are exposed to high loads, which leads to increased wear and more frequent tool failures.
Our research focuses on the regeneration of defective moulding tools. Within the scope of the project, the research group develops a virtual assistance system. The virtual system includes the combination of additive and metal cutting processes. By linking virtual planning and measuring technology inside the tool machine, the assistance system enables automated and process-reliable reworking of defective moulding tools. The research results will be presented in a demonstration machine.
