ABSTRACT --- The experimental conditions chosen as a reference for the 2007
edition of the extrusion benchmark that was held in Bologna, Italy, 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, and profile exit temperature.
