Abstract: The sealing apparatus for use in an extruder simplifies the conventional complexed structure. The modified structure enhances the sealing efficiency as inner pressure of the container causes an extrusion deformation of a metal seal(Be-Cu alloy) to increase. It is characterized in that a channel shaped metal seal(z') having a pair of protrudent lips is installed between a ram(1) and a antainer; the lips being in contact with the walls of the ram and the container. The length and thickness of the protrudent lips of the metal seal(3) is determined by considering the maximum pressure within the container(2) and the elongation ratio of the metal seal(3) when designing it.
