Experimental investigation on the flow behavior of liquid aluminum inside pressure-die-casting dies using high-speed photography

An experimental investigation on the flow behavior of molten aluminium inside the pressuredie-casting dies for manufacturing electric motor rotors by using flow visualization and high speed photography is reported in this paper. The experiments were in fact carried out on several models made of organic glass, in which water instead of liquid aluminium was adopted as the test liquid by virtue of the principle of dynamic similitude in hydraulics. The observed results obtained from the models show a reasonable agreement with those from corresponding prototypes, and therefore provide a valuable scientific basis for the design of the casting dies, and for the selection of technological parameters of the pressuredie-casting and further theoretical analysis.
