A METHOD FOR ANALYSING THE EFFECT OF FLOW ON HEAT TRANSFER IN DIE CASTING

A new method has been developed for determining the effect of flow on heat transfer in die casting during steady production. Aside from the assumption that the casting is thin in comparison with its overall size, there are no restrictions on either the die or casting geometry. Important questions concerning the nature and significance of heat transfer during flow are addressed by analysing a representative two‐dimensional die. The results show that the effect of flow can be critical when the fill time is long, the casting is thin, or the thermal conductance of the die lubricant is high.
