FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of foamed aluminium sheets. It may be used in civil engineering, nuclear power engineering, ship building, aircraft engineering, etc. Blank of compacted powder mix sheet with clad top and bottom is placed at foaming die. Said blank is fed horizontally into foaming die inclined toward blank as far as it goes to lifted side inner surface. Thereafter, down side is lifted. Now, powder mix is foamed in furnace to cool foam aluminium panel and to withdraw foamed panel by vertical displacement of die relative to foamed panel from top to bottom.
EFFECT: lower metal input, simplified process, higher reliability.
