PURPOSE: To execute the compaction and extrusion molding of powder continuously and to obtain an extrusion molding having uniform characteristics by inserting a preformed disk into a container bore and closing the molding hole of a die so as to counter the compaction of the powder.

CONSTITUTION: The disk 14 having required strength is obtd. by molding the powder 11. The disk 14 is inserted into the container bore 2 to close the molding hole of the die 7. The powder 11 is then packed into the container bore 2 and the powder 11 is maintained at a required temp. The powder 11 is extruded. The compression and extrusion molding are thus continuously executed.
