摘要
A hot stamping system of the present invention performs heat treatment by injecting cooling water of an interior and exterior portion with respect to first and second close sections (100-1, 100-2) of a bumper beam (100) put on an upper mold (20) and a lower mold (30) simultaneously, wherein the upper mold and the lower mold are merged. Thus, an automobile structural member manufactured by the hot stamping method has a collision performance with a strength deviation within 1.2%. In particular, remarkably improved cooling effect and uniformity are used to expand the hot stamping method with respect to the automobile structural member having at least three close sections.;COPYRIGHT KIPO 2018
