Quantitative Prediction Method for Shrinkage Porosity Considering Molten Metal Supply by Pressure in Squeeze Casting

Abstract

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 has been investigated by changing squeezed pressure. As the results, the predicted size of shrinkage porosities was found to agree well with the sizes of shrinkage porosities of the actual castings.
