Extrusion is a process of cold bulk metal forming for manufacturing near-net shape pre-forms or components from circular blanks, billet sections, tubes and the like. In order to produce complex components, extrusion is also performed in warm or hot forming.

The workpiece material is displaced in a shaping tool and flows into an intended opening of the die while changing its cross-section. The required component geometries can be quite complex. Several process variants of extrusion are available to realize a large variety of shapes. These process variants are combined with one another sequentially or parallel.
