摘要： A method for molding powders which comprises the steps of introducing a thin-wall resilient mold (9) inside a ventilative mold support (6), reducing outside pressure of the ventilative mold support to less than the atmospheric pressure (760 Torr), putting the thin-­wall resilient mold exactly close to the inside wall of the ventilative mold support, supplying material powders (13) into the thin-wall resilient mold, exhausting air existing in the voids which the material powders form, and taking the ventilative mold support apart to apply cold isostatic press treatment to the thin-wall resilient mold. The shape of the thin-wall resilient mold is similar to the shape of the ventilative mold support.

摘要翻译： 一种粉末成型方法，包括以下步骤：将薄壁弹性模具（9）引入通气模具支架（6）内，将通气模具支架的外部压力降低至小于大气压（760托），将 薄壁弹性模具精确地靠近通风模具支架的内壁，将材料粉末（13）供应到薄壁弹性模具中，排出存在于材料粉末形成的空隙中的空气，并将通风模具支撑件分开 将冷等静压处理应用于薄壁弹性模具。 薄壁弹性模具的形状类似于通风模具支架的形状。
