Swaging, or round hammering, is a precise procedure for the chipless transformation of pipes, wires and rods.


This procedure is appropriate for cold forming rotationally symmetrical metal parts and offers a short processing time in addition to the advantage of high surface quality.


The final contour of the work pieces is hammered round with special forming tools (two to eight, usually four swaging jaws), which are arranged concentrically around the work piece.


In principle, tools (ram or swaging jaws) specially driven by shaft hammer on the component during the entire forming process.
