An extrusion method using an extrusion press including an end platen to which a pressure ring is provided, a die, a container, a drive part for movement of the container, and a main cylinder device having an extrusion stem to form a billet into a shape includes extruding the billet loaded in the container by the extrusion stem from the die to shape it to an extruded material, releasing sealing pressure from the die, cutting the billet between the die and the container and between the die and the pressure ring by moving the die, and resuming shaping of extruded materials by the billet remaining inside the container.
