Abstract:
A method produces a press-molded article having a hat shaped cross-section with flanges at both sides, a top plate, vertical walls at both sides, and having a shape curved in the vertical direction to an inverted checkmark shape along the longitudinal direction when the molded article is viewed from a side face with the top plate section on the top side. An intermediate molded body is formed by drawing a metal stock sheet into an intermediate shape, and after preparing the outside shape of the intermediate molded body by trimming, drawing is subsequently performed to form the final shape.
