Method for molding powders.

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.
