Abstract
An improved continuous hydrostatic extrusion process and apparatus for metals is disclosed. In order to reduce the leaks of viscous fluid through the clearances between the rotor and the stator, which clearances are necessary for operation of the apparatus, the drive fluid used in the groove of the rotor to cause forward movement of the blank is of a higher viscosity than the fluid in the isostatic chamber in which extrusion pressure is present. The pumping power is acccordingly greatly reduced and it is possible to avoid the use of expensive and delicate pressure multiplying means.
