The experimental conditions chosen as a reference for the 2007 edition of the extrusion benchmark and the corresponding main results are summarized in this work. The die design stage is first explained in order to address the main features of the experiment and its objectives. The die is a flat one with multiple holes; four angular profiles were produced with different pocket geometries, the experimental plan being entirely described. The initial temperatures for the billet and the die set, together with the temperature development during the process strokes, are also reported. The results are shown, for each profile, in terms of final profile length, mean exit speed, global process load, profile exit temperature.
