Fujitsu Limited and Daido University Professor Yasuhiro Maeda have jointly developed new simulation technology that can accurately replicate splash and wave behavior in the surface of molten metals when they are being poured. In the casting process, which is used in component manufacturing in a variety of fields, such as automobiles and IT devices, molten metal is poured into a mold to be cast into a shape. The way molten metal flows through the interior of a mold significantly effects casting quality, but because the interior is impossible to see, there has been a demand for a simulation that can clarify how molten metal flows within the mold. However, simulation of this flow has been difficult to achieve as the way molten metal flows can change greatly depending on the oxide film that forms when metal contacts the air.
