description PURPOSE: A mold method for preventing a shock mark of pre-coated metal (PCM) and vinyl-coated metal (VCM) materials from being exposed is provided to mold a steel material so that the shock mark is not exposed, to flange-up only a straight portion and cut the curved portion from a notching process by excluding the curved portion of a material from a flange-up process. CONSTITUTION: A mold method for preventing a shock mark of PCM and VCM is as follows. When the material that is seated in the blank holder of a mold is drawing-molded, the lower bottom of a die is molded deeper than the bottom surface of a product (S10). The entire circumference is cut by using a punch and the die according to the dimension of a flange (S20). The die flange-ups the flat flange in a straight portion, and maintains the shapes of curved portions (fours edges) in a trimming process by the curved portions leaving from the die (S30). The die and punch are configured according to the shapes of the flange front portion and the piercing of a side wall portion, and thus a cam slide moves forward and cuts by a cam drive descending (S40). The cam drive moves the cam slide forward by a press ram descending, and thus the material is bent by a bending punch (S50, S60).
