Over the past decades, hot stamping technology has been gradually applied to the production of ultra high-strength automotive components. Although automotive components such as bumpers, door impact beams, center pillar reinforces have been produced by hot stamping and installed in many cars worldwide, this promising technology has not spread as much as expected. One of the major reasons is its high production cost caused by the low productivity of this technology. In this study, we propose a new hot stamping technology characterized by high productivity, which significantly reduces the cycle time of stamping and minimizes or omits laser trimming and piercing.
