  • Patent number: 6745609
    Abstract: An improved stamping die assembly is provided for controlling the flow of sheet metal during the draw forming process. The die assembly includes a textured die surface on the one or both sides of the binder mating surfaces that replaces conventional draw and lock beads. The textured die surface can be formed using direct metal deposition of a hard material, harder than the existing die surfaces, on the existing die base material to achieve an engineered textured surface. The textured die surface optimizes the performance of the die by enabling longer die life, higher coefficients of friction between the mating binder surfaces and reduction of wrinkles and stringers typically caused by draw and lock beads in the draw forming process.
