Swaging
swaging
[′swāj·iŋ]Swaging
a forging process that reduces the cross-sectional area and increases the length of a billet by the plastic deformation that results from the application of a radial, compressive force. Rods and thick-walled tubing are swaged in rotational swaging machines to yield reduced rods, wire, and shaped conical articles, as well as graduated solid and hollow shafts. Thin-walled, hollow billets are swaged in the hollow part of a die; for example, the necks of cartridge cases are shaped in this way. The tools used in swaging are called swages.
