For centuries, the production of metal semifinished products implied transforming the casted material into bars or plates, then cooling, moving,reheating and finally give them a shape. it was a great effort in terms of time, space, water and energy to produce just a few kilos of product per day. In 1948 Ilario Properzi patented the Continuum Properzi to produce kilos of rod with one single machine in only a few minutes starting from casted metal.
