FIELD: technological processes.
SUBSTANCE: invention relates to metal forming at production of car body component by stamping. Component comprises an upper plate, upper ribs, vertical walls, lower ribs and base flanges. Flange of the vertical wall and the flange of the base adjacent to its end section are continuous. At the first stage, the workpiece is forged to form an intermediate molded article.
