The CRIMSON (Constrained Rapid Induction Melting Single Shot Up-Casting) method uses a rapid in-duction furnace to melt just enough metal for a single mould rather than bulk melting used in traditionalcasting process. The molten metal is then transferred to a computerecontrolled platform to completethe counter-gravity upfilling. The highly controlled metalflow is pushed into the mould tofinish thepouring and solidification. In the present paper the energy saving capability of CRIMSON approach iscompared with conventional sand casting process. The paper focuses on the energy and resource effi-ciency optimization of casting stages through simulation and life cycle assessment analysis simulation forproposing alternative means for the better performance of such processes. It is proven that the CRIMSONprocess can produce high quality castings with higher energy efficiency and lower environmental impact.©2016 The Authors. Published by Elsevier Ltd.
