Abstract

This paper presents a point of view and a method which is to use temperature gradient in die wall and boundary layer as estimation of quantity of heat flow of dies. Through pratical measurement and calculation

the influence of die wall temperature

metal released heat

dies wall increased heat by different cooling conditions have been researched. The heat resistance of computer solidification process numerical value simulation is 2.6 cm 2·K·s/J in the die system.
