ABSTRACT:
In a press for hydrostatic extrusion which has a prestressed outer supporting member and an inner tube or liner, the end surfaces of the inner tube are inwardly inclined towards its center with an inclination of at least 1:20, and the seal holders which take up forces operating on the seals have inclined end surfaces which make contact with the inclined end surface of the inner tube. The sealing arrangement includes a first sealing ring with a cylindrical inner surface which contacts the punch and the die respectively, and an end surface making contact with the support ring, and a second sealing ring with an outer cylindrical sealing surface which makes contact with the inner tube and an inclined end surface which makes contact with the inclined end surface of the support ring.
