Based on the principle of hot stamping, a simulation model of hot stamping was established. The blank contour line of U part was optimized by using a multiple iterative algorithm. By comparison with the simulation and experimental data, the multiple iterative optimization algorithm was verified. Moreover, the blank contour lines of a bumper and the B-pillar of Numisheet 2008 were optimized. The result showed that the multiple iterative method for optimizing initial blank contour line had high calculating speed and precision. The hot stamping parts’ contour lines match the ideal part contour lines quite well.
