Research on optimization design of the heating/cooling channels for rapid heat cycle molding based on response surface methodology and constrained particle swarm optimization

► We develop a method for optimum heating/cooling channels design of RHCM mold. ► A multi-objective optimization method is developed based on RSM and PSO. ► Energy equations in the heating and cooling processes of RHCM are deduced. ► Some guidelines to improve thermal response efficiency of RHCM mold are presented.
