Abstract:
A method containing the steps of: providing an inner structural part blank having a L-shape and an outer structural part blank having a L-shape, the inner and outer structural part blanks being substantially planar; hot stamping the inner structural part blank to form an inner automotive structural part having an inner lowerside sill part and an inner lower front pillar part made of a single part with the inner lowerside sill part; hot stamping the outer structural part blank to form an outer automotive structural part having an outer lowerside sill part and an outer lower front pillar part made of a single part with the outer lowerside sill part; and assembling the inner automotive structural part and the outer automotive structural part to form the automotive structural part.
