To calculate the process energy consumption of sand casting,a model for energy con-sumption was built based on Petri net.The process of sand casting energy consumption was huge,and had a large potential for energy saving.A process activity model was proposed with analyzing the characteristics of energy consumption.The relationship between process activity and resource con-sumption was described by graphical description based on Petri net.The consumption model of sand casting process activity was realized.The proposed method was verified through the sand molding workshop.
