GMT as an innovative industrial partner for a variety of research projects

GMT is constantly involved in R&D projects, either as active research partner or in project support committees. GMT contributes its specialist knowledge and creativity. We are always interested in research projects related to metal materials: from heating and processing up to quality control in the field of material development and control.
We are very well-acquainted with the application and handling of research projects. Please contact us for your questions!

WI+R network: AdEle

WI+R – Digital repair factory Berlin-Brandenburg – shaping of structural change by innovation in maintenance, servicing and repair – Cottbus. Maintenance, servicing and repair (WI+R) are changed in depth by digitalization. The cooperation of more than 100 players and the founding of research institutes is to create widespread participation for digital solutions on a national level. GMT participates in the project AdEle with the subject additively produced spare parts. When using additively produced spare parts, an important factor is to estimate their service life and to adapt their design to the properties, which can be achieved by means of additive production. This requires precise knowledge on how the material properties of the product can be adapted through additive production.

ZIM-Project: RESI

Resource-saving heating of bars by means of intelligent induction plants (RESI). Within the framework of the user-oriented R&D project, funded by ZIM, GMT develops with GFaI (Society for the Advancement of Applied Computer Science) and BTU (Brandenburg University of technology) Cottbus-Senftenberg a plant control for induction heating plants based on the materials used. For this purpose, material data of different materials are collected during inductive heating and processed in the material data base MatILDa®. Furthermore, automated learning algorithms and data analysis are implemented to recognize the material to be processed on the basis of its heating behavior as well as to select its optimum heat treating parameters avoiding an extensive trial-and-error process. The result is an intelligent control, which determines the optimum heating power depending on the material, and controls it during the process so that the risk for local overheating is minimized.

ZIM-Project: ESPE

Development of shortened forging process chains by using thermo-mechanically treated raw materials. In cooperation with the IFUM - Institute of Forming Technology and Machines of the University of Hanover, a material concept and an adapted process line was developed, which allows the manufacture of solid formed parts with an improved toughness-strength ratio in shortened process chains. By combining the project-specific thermo-mechanical treatment of the raw material with a corresponding solid forming step, the ultrafine real structures reached during the thermo-mechanical treatment and the combination of properties can be transferred to the solid forming parts. Separate heat treatment after forging, which is common in conventional processes, can be eliminated, thus shortening the project-relevant process chain.

ZIM-Network: METALNET

METALNET Customers of the network ask more and more for an end-to-end service chain: starting from the conceptual engineering and process simulation up to design and implementation of a machine and plant concept in manufacturing. Therefore, seven companies from the sectors process development, simulation, automation, image processing and mechanical engineering founded the network “METALNET” in 2002. For a period of 3 years, the network was funded by the Federal Ministry of Economics and Labor (BMWA). The advantages are most obvious, when individual solutions are required, either to optimize a process or to develop and/or modernize a technical plant. To date, the activities of the network have an effect in the form of continuing partnerships and professional exchange.
