Energy-Flexible Operation of Pressure Die-Casting Systems

This research news article discusses the development of bivalent furnaces by the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, aimed at enhancing the energy flexibility of pressure die-casting systems. The article outlines the significant energy consumption associated with melting and holding furnaces, which contributes to high production costs in the casting industry. The bivalent furnace technology allows for dynamic switching between gas and electricity, enabling manufacturers to optimize energy usage based on fluctuating electricity prices. The research team, in collaboration with industry partners, has successfully implemented this technology in a crucible furnace at Bark Magnesium GmbH's die-casting foundry. The furnace operates continuously without interruptions during energy source transitions, contributing to cost efficiency and supporting the shift towards renewable energy. The article also mentions ongoing research efforts to further optimize the furnace's design and explore the potential use of hydrogen as an energy source.
