Entwicklung von Kriterien zur Kommunikation der Energieeffizienz von Kunststoff verarbeitenden Maschinen

The aim of this project is the development of an energy efficiency label for plastics processing machines in close cooperation with industrial partners. This allows marketing and communicating highly energy efficient plastic processing machines. Manufacturers should be motivated to develop more energy-efficient machines. As the efficiency criteria for evaluating the energy consumption of plastics processing machinery the specific energy consumption SEC [kW/kg] is used. In order to compare these criteria an energy measurement standard for injection moulding and extrusion has been developed. For injection moulding the EUROMAP 60 has been adapted based on the proposal worked out from the project team, now for download at the EUROMAP recommendations under: www.euromap.org. For extruders, a working group to create a new Energy measurement standard EUROMAP 90 was founded, but no consensus could be found yet. To communicate the two energy efficiency labels, different approaches have been chosen in the next step. The aim is the development of two labels, one for an internal company concerning the communication of the energy demand according to the EUROMAP 60 for injection moulding and the second for extrusion concerning the whole branch. The classification of the machines is made by the Energy Efficiency Index (EEI). The EEI can be calculated from the measured specific energy consumption SEC, the theoretically required energy for melting and three constant correction factors. Furthermore the energy efficiency of the machines has been grouped in energy classes. ...
