Published Online: October 4, 2010
...J. J. Hernández-Ortega; R. Zamora; J. Palacios; J. López; F. Faura One of the most important problems encountered in die-casting processes is porosity due to air entrapment in the molten metal during the injection process. The aim of this work is to study experimentally and numerically...
