Casting Defect Simulation, Analysis and Prediction Prosim

Casting defects occur during. Flow of molten metal in the die / mold cavity; Heat transfer (loss of heat during the flow of melt) Solidification (cooling after the die cavity is completely filled) Using computer simulation of metal casting process, accurate prediction of the casting defects is possible.
