As a molding material production method and its molding material for producing a molding material having a flange formed on the body portion and the end of the body portion of the tube-shaped from the material plate, thick unnecessary additional flange member formed in accordance with the load, to wrinkles and buckling avoided, and provides a molding material production method and a molding material, which enables the reduction in size of the molding material weight or the material plate. According as the at least one time of producing the drawing-out process and a drawing-out molding material by molding, including at least one time of drawing is carried out after the machining, the first drawing by opening the die and drawing the sleeve for the area corresponding to the body portion the embodiment, and to maintain a constant spacing of the mold gap between the die and the drawing of the sleeve for the area corresponding to the flange is subjected to ironing.
