The effects of heat released during fill on the deflections of die casting dies

The quality of a die cast product is determined to a great extent by the mechanism of cavity fill. The evolution of this process has received attention both in industry and literature. Because of its effect on the cost of a numerical simulation, the question of whether or not the filling stage takes place under isothermal conditions needs to be addressed. This article analyzes the process of fill in die casting and presents relations that can be used to predict those conditions under which heat release may be significant. In order to put the relevance of fill conditions in context, the effects of heat released during fill on the prediction of die casting die deflections are introduced and discussed.
