Downsizing and energy savings are key words in the automotive industry. Danieli Breda & C.'s R&D department studied a way to quench the cylinders' thirst for oil between the empty dead cycle time and the extrusion phase, and has patented a 23MN extrusion press prototype that completely discards the old dead cycle time. The project is based on twin containers laterally shifting. During extrusion, the billet that waits to be processed can be loaded outside the extrusion axis; at the end of the extrusion, the twin containers shift laterally and the new extrusion can start immediately. In this way, the cylinders' oil demand is balanced during dead cycle time and extrusion phase, so that the number of installed pumps depends just on the extrusion speed. Last but not least, the dead cycle time is drastically reduced.
