...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...

... temperatures. As an example, the effect of the local surface temperature of a casting die on the cooling water outlet temperature is analyzed from a laboratory die casting process simulator. Based on the system identification theory, a control-oriented linear time-invariant model has been developed, which...

...R. Zamora; J. J. Hernandez-Ortega; F. Faura; J. Lopez; J. Hernandez The air entrapment mechanisms in die-casting injection chambers that may produce porosity in manufactured parts are analyzed in this work using visualization techniques of the flow in a transparent injection chamber model, using...

...L. D. Clark; M. T. Alonso Rasgado; K. Davey; S. Hinduja The rate of heat extraction during the pressure die casting process is central to both the quality and the cost of finished castings. Recent efforts to reduce the thermal resistance of dies by optimizing the effectiveness of the cooling...

...A. Nouri-Borujerdi; J. A. Goldak In this study an analytical model has been developed to describe air pressure and residual air mass variations in pressure die casting for atmospheric venting. During injection of molten metal into a die cavity, air is evacuated from the cavity through vents...
