A pressing tool for producing shell- or plate-like pressings, as for example crockery plates, beakers, cups, bowls and the like, from powder material, more specially of a ceramic nature, made up of a stamp (10) and a counter-stamp (11), whose facing end faces are responsible for forming the top and lower sides of the shell-like pressings on pressing the powder material placed therebetween, the stamp (10) and the counter stamp (11) being able to be moved along a level axis towards each other, the powder material being run into a space walled in by the end faces of the stamp and counter-stamp and by a ring-like die (12) placed round the stamp and the counter-stamp, said die being able to be moved into the filling position, characterized in that the die (12) has a shutt-off ring-like space (13) on its inner side, said space being in connection with a supply of the powder material, in that at least one of the edges of the end faces of the stamp (10) and the counter-stamp (11) is designed running out towards the edge of the other end face like a ring (at 20) and in that the stamp (10) and the counter-stamp (11) may be moved so far towards each other that a small axial ring-like gap is kept between the edges of their end faces.
