ABSTRACT:
In manufacturing products by enclosing a body of powder in a capsule and compacting it into a solid body by subjecting it to high temperature and high all-sided pressure, a capsule is used which has a connection sleeve in one wall with a through opening for connection of a capsule to the vacuum pump. An arrangement is provided for exerting an external outward pressure on this sleeve, so as to lift the wall away from the surface of the powder within the container, so that a large surface area is provided to permit easier release of gases when the capsule is subjected to vacuum. Thereafter, a plug is inserted in the opening of the connection sleeve, so as to seal the opening.
