    摘要： A spacer for use with a core rod, a flexible tubular mold disposed about the core rod, means introducing a powder between the core rod and the mold, and means sealing the ends of the tubular mold so that the powder may be compacted on subjecting the mold to fluid pressure, the compacted powder being removed and sintered to form porous seamless tubing; the spacer having a cylindrical outer shell larger in diameter than the inside of the mold, guide means sliding on the core rod and fixed to the shell positioning the shell concentrically about the core rod, the spacer containing at least one longitudinal opening allowing powder to flow therethrough, and handle means extending through the mold between the mold and the core rod so the spacer may be drawn upward through the tubular mold as powder flows through the opening in the spacer to be positioned about the core rod within the mold, the tubular mold on passage of the spacer contracting to hold powder against shifting.

    摘要翻译： 用于芯棒的间隔件，围绕芯棒设置的柔性管状模具，意味着在芯棒和模具之间引入粉末，以及密封管状模具的端部的装置，使得粉末可以在经受 模具到流体压力，去除压实的粉末并烧结以形成多孔无缝管; 所述间隔件具有直径大于所述模具内部的圆柱形外壳，所述导向装置在所述芯棒上滑动并固定到所述壳体，所述壳体围绕所述芯棒同心地定位所述壳体，所述间隔件包含允许粉末流动的至少一个纵向开口 以及通过模具延伸穿过模具和芯棒之间的手柄装置，使得当粉末流过间隔件中的开口以便围绕模具内的芯棒定位时，间隔件可以向上拉出通过管状模具，管状模具 通过间隔件收缩以保持粉末不会偏移。
