ABSTRACT:
In isostatic hot pressing of powder in a collapsible container, the powder is enclosed in a container which is provided with one or more evacuation openings, and a conical support is held in position adjacent the evacuation openings. A funnel-shaped body of sheet metal is secured above the support and the evacuation openings by welding its edge to the wall of the container. The body is evacuated through a suction tube connected to the funnel and the tube is sealed. Thereafter the container is subjected to heat and pressure, and the funnel-shaped member collapses into engagement with the conical support.
