KraussMaffei (Munich) has concluded its ZuPrEff collaborative injection molding research project, which, the company says, achieved energy savings of up to 35%, exceeding forecast values. "We consider the condition-dependent management of the injection molding process to have by far the greatest potential for future increases in productivity in injection molding production," said Reinhard Schiffers, head of machine technology and testing at KraussMaffei.
The goal of the project (ZuPrEff stands for "Condition-dependent process management for energy-efficient and resource-conserving production of plastic formed parts") was to "optimize production results and lower costs with robust and energy-efficient processes." KraussMaffei partnered with gwk, Krallman, the University of Rosenheim, and the Fraunhofer Institute IPA on the project.
In order to achieve significant improvements in energy efficiency along with robust process reliability, the company says the task was to "optimize individual processes such as melt preparation and mold tempering and subsequently establish an interlinked system for monitoring the entire process, particularly with a combined machine and heat-balancing control system." ...
