  • Sealing device for indirect extrusion die

    Abstract: A sealing element for a die which may be used in indirect extrusion is disclosed. The sealing element is in the form of an annular member removably supported on the die. The sealing element has an outer dimension greater than that of the die and one which closely conforms to the inner dimension of a container through which the die is adapted to move. The sealing element provides a lip forming a radially inwardly directed extension of its forward surface, which lip overlies the line of junction between the sealing element and the die.
