    • 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.
    • 挤压机的挤出成型方法包括将其外表面经受吠处理的坯料装入容器中并以预定长度的方式挤出坯料的第一步骤,第二步骤 将下一个坯料装入容器的步骤,另外用随后的坯料挤压前述坯料,以便留下预定长度的后续坯料; 以及第三步骤,将下一个坯料装载到容器中,并且以随后的坯料另外挤压前述坯料,以便留下预定的后续坯料的长度并停止挤压。 通过这些步骤,容器在保持与模具的接触的同时不移动,并且通过剩余和额外的挤出连续地挤出坯料。
