The invention relates to a powder press () for producing a pressed article from a material that can be pressed, having a press frame (), an upper and/or lower punch assembly () and a die assembly, which define a molding cavity, into which the material that can be pressed can be introduced, and an electric drive unit () which is operatively connected to the punch assemblies () and/or the die assembly, wherein, in order to mold the pressed article, the punch assemblies () and the die assembly can be moved relative to each other along a pressing axis () and pressed against each other by means of the electric drive unit (). Furthermore, the operative connection between the electric drive unit () and one of the punch assemblies () comprises a toggle lever drive () which moves the punch assembly () into a pressing end position along the pressing axis ().

The coach body construction comprises an upper structure having extruded profiles, which are connected detachably to one another by corner connectors and are made of an aluminum alloy, and a lower structure. The lower structure is composed of longitudinal and transverse supports which are made of an extruded aluminum alloy and are detachably connected to one another and to the upper structure by corner connectors. In interaction with the upper structure, it is of inherently sturdy construction. The corner connectors are, in particular, screw-on corner connectors.
