  • Blow molding extrusion die with rectangular slots
    Patent number: 5486333
    Abstract: A die for a blow molding machine has at least one circumferential rectangular cutout section contiguous with the die exit in at least the die ring or the mandrel. The rectangular cutout section expands the material flow channel between the die ring and the mandrel to increase the volume flow of material passing through the die exit at the rectangular cutout section. However, the constant length of the rectangular cutout section in a longitudinal direction maintains a constant linear velocity of material flowing through the die exit.
