    摘要： An extrusion molding method of an extrusion press includes a first step of loading a billet, the outer surface of which is subjected to a barking treatment, into a container, and extruding the billet in such a manner as to leave a predetermined length, a second step of loading a next billet into the container, additionally extruding the preceding billet with the succeeding billet in such a manner as to leave a predetermined length of the succeeding billet; and a third step of loading a next billet into the container and additionally extruding the preceding billet with the succeeding billet in such a manner as to leave a predetermined discard length of the succeeding billet and stopping extrusion. By way of these steps, the container does not move while maintaining contact with a die, and the billet is continuously extruded by leftover and additional extrusion.

    摘要： An extruder is formed of a container having a container liner for receiving a billet therein, an extrusion stem situated near the container for disposing the billet into the container, and a two-piece seal block installed between the container and the extrusion stem for sealing therebetween. The seal block is formed of two seal block sections for sandwiching the extrusion stem therebetween. Each seal block section includes a base piece having a press member, and a holding block detachably attached to the base piece to be moved by the press member and having a first sealing member facing the extrusion stem and a second sealing member facing the container. A moving device is attached to the seal block sections for moving the seal block sections relative to the extrusion stem. The holding block is urged to the extrusion stem by the moving device, and to the container by the press member to thereby seal between the container and the extrusion stem.

    摘要： An extrusion press has a sealing and suction device (30; 230; 330) mounted around a plunger (18; 118) with the possibility of sliding axially along the same; the device creates an airtight seal against a back face (25) of a container (20) for a billet (B) when the plunger is working within an inner chamber (24) of the container. A vacuum is created inside the chamber as soon as the plunger enters the chamber before extrusion of the billet begins.

    摘要： Double-stem type extrusion method and apparatus used for extrusion-molding rod-like and tubular products. In order to upset a solid or hollow billet (5, 5A) supplied to a container (1), the end of the container (1) which is on the side of a press stem (6) is closed with a blistering-preventing cover (11) which is not moved relatively to the container (1). A pressure is then applied to the billet (5, 5A) from the side of a die (8) to start the yield deformation thereof from the same side thereof. As the yield deformation movement of the billet (5, 5A) progresses, the air existing between the inner surface of the container and billet (5, 5A) is discharged from the portion of the container (1) which is on the side of the cover (11).
