Continuous Pre-forming — With the continuous pre-forming method, the forging is given a defined pre-shape in a single forming movement. Some of the traditionally used pre-forming units are hydraulic or mechanical presses as well as cross rolls. The continuous process offers the advantage, especially for aluminum, that the short process involves only little cooling for the component and high cycle times can be reached. A disadvantage is that the degree of forming is often limited in the pre-forming process, since only a limited amount of energy and a limited forming capability are available for the component within a single stroke (of the press) or a single revolution.
