It is important to predict shrinkage porosity quantitatively in squeeze casting process by CAE. A new calculation method has been developed considering molten metal supply by pressure in squeeze casting. Using this method, the size of shrinkage-porosity in an aluminum suspension part can be simulated quantitatively. The predicted results were compared with the X-ray inspected results of actual castings, and the size of shrinkage porosity was investigated by changing squeeze pressure. As a result, the predicted size of shrinkage porosities was found to agree well with the sizes of shrinkage porosities of the actual castings.
