A direct or indirect extrusion press is disclosed, which includes a container (20) that defines a chamber (19) to hold a billet (11) to be extruded, a ram (12), a die (14), a die holder (41), a base (13) and a shears (15) to shear heels (17) of the billets (11). The die (14) is movable axially to the container (20) or vice versa. The container (20) defines at least two chambers (19) and is movable in a plane perpendicular to the plane on which the axis of the chamber (19) and the die (14) lies. An extrusion plant which includes a press as described above is also disclosed. The extrusion plant includes three stations that perform extrusion (19a), charging (19b) and the cleaning and readying of chambers (19c) respectively, the stations cooperating respectively with the chambers (19).
