FIELD: metallurgy.
SUBSTANCE: invention relates to field of plastic working and can be used at manufacturing by punching of composite parts, used, for example in automobile industry. At least one side of steel sheet of thickness less than 0.65 mm is coated by at least one sticky polymer film. Total thickness of films is equal to at least 0.1 mm. In case of necessity received lamellar steel sheet is cut for receiving of sheet billet. Then laminated sheet or blank is formed on forging press by means of puncheon, mould and sheet-holder. Distance between puncheon and mould is controlled so that its value is in provided range.
EFFECT: there is excluded appearance on detail at its formation of folds and ruptures.
