Device for manufacturing a metal profile

An extrusion press device for manufacturing a profile from an extrusion block (36) of a material that is at least in part metallic, whereby the extrusion press device (5) contains a container (10) with a container bore (12) for accommodating the extrusion block (36), a stem (32), a shaping means (18) and a heating facility (25) situated between the container bore (12) and the shaping means, the improvement comprising:

• the heating facility (25) contains a heating chamber (22) in the form of a hollow body arranged, with respect to the direction of extrusion x, following the container (10) and includes at least a first and a second heating section (22a, 22b) with heating chamber walls (26a, 25b) and means (30) for heating the heating chamber walls (26a, 26b), wherein the first heating section (22a) exhibits a larger cross-sectional diameter than the second heating section (22b) with respect to the direction of extrusion x, wherein a transition which includes a step is between the first heating section and the second heating section.
