CONTINUOUS METAL EXTRUDING DEVICE Abstract of the Disclosure A method and apparatus for continuously extruding non-ferrous metal is shown and described wherein solid metal, such as bar stock, is fed into an entry port of an entirely enclosed melting crucible until the crucible is full of molten metal. A seal is maintained between the metal being fed and the entry port to establish pressure in the crucible and to prevent leakage back through the entry port. When the crucible is full, means are provided to re-solidify the molten metal adjacent a closed exit port. Thereupon, the exit port is opened and the re-solidi- fied metal is extruded through the exit port at the same volumetric rate is metal is fed through the entry port.
