Foundry rejections due to "cold shut" defects on the surface of a graphite cast iron casting made by the "H" Process have been greatly reduced by computer simulation aided optimizing gate-system design. Tohoku University has developed a simulation program named Stefan3D, which has been proved to be very good at mould filling simulation, due to its improved SOLA_VOF method.1 This software was used in the present study to define the experimental process. The results of the simulation are in good agreement with the corresponding experiments.
