Energy efficiency in production

MAFAC is a partner of ETA-Factory

In its project "Energy-efficient factory", the Institut für Produktionsmanagement, Technologie und Werkzeugmaschinen (PTW) of Darmstadt Technical University investigates the energy savings potential in industrial production by co-action of all company departments.

The "Energieeffizienten Fabrik für interdisziplinäre Technologie- und Anwendungsforschung" (ETA) is the first tool to investigate and optimize the energy efficiency of the entire industrial production process.

For this purpose, a representative process chain with high optimization potential was selected. In addition to three metal-cutting processes and one thermal treatment process, two cleaning processes - implemented by MAFAC - are part of the picture. Among others, BMW, BOSCH, DAIMLER, EMAG, BOSCH Rexroth, OPEL, SIEMENS, Stuttgart university, and VIESSMANN are also involved in the research team.

The project is based on the assumption that the overall energy saving potential will be higher with a linked optimisation of building envelope, technical building infrastructure and production machines, than with a separate optimisation of each individual component. The waste heat generated by the machines, for example, can be used directly for air conditioning or for the heat requirements of a parts washer.

After two years of preparation, the research project was officially launched in May 2013. The start of construction of the 650 sqm hall is scheduled for 2014, the completion for 2015. The Bundesministerium für Wirtschaft und Technologie (BMWi), the Federal State of Hesse and the university fund the «ETA-Factory» project with a total of eleven million Euro.

At the AMB 2014 in Stuttgart, the project is presented to the public as a part of the special exhibition "Innovation Tour Metal Working".
