Abstract
A method for molding powders which comprises introducing a thin-wall resilient mold inside a ventilative mold support, reducing the outside pressure of the ventilative mold support to less than the atmospheric pressure (760 Torr), putting a thin-wall resilient mold exactly close to the inside wall of the ventilative mold support, supplying powder material into the thin-wall resilient mold, exhausting air existing in the voids formed in the powder material, 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.
