Investigating the energy consumption of casting process by multiple life cycle method

The Constrained Rapid Induction Melting Single Shot Up-Casting (CRIMSON) process is an alternative casting process to conventional casting that can be used for small to medium batch production. The aim of the process is to improve the casting quality and reduce the energy consumption within light-metal casting industry. Multiple life cycle method was used in this paper to investigate the energy consumption of the casting process. From the investigation, it was shown that energy consumption of the casting production is influenced by the Operational Material Efficiency (OME): the higher the OME the lower energy consumption of the casting production. It is concluded that the CRIMSON Process only use 23% of energy compared with conventional method for the same casting production. By adopting the CRIMSON method, 130 GJ/tonne of energy can be saved for aluminium casting production.
