Rotary swaging

Rotary swaging – lightweight construction and variety of shapes

Rotary swaging is a gradual process of compressive forming for reducing the cross-section of mainly rotationally-symmetric components. In principle, rotary swaging exists in two process variants.

In feed swaging comparably long reduced cross-sections are generated with a flat angle of transition. In contrast, recess swaging produces local reductions of cross-sections with steep angles of transition. Here the workpiece is completely or partially enclosed by two or several tool segments. With each downward movement a part of the workpiece is formed depending on tool geometry and stroke. In addition to a variation of outer and inner diameters, it is also possible to simultaneously manufacture inner profiles.
