Swaging


swaging

[′swāj·iŋ] (metallurgy) Tapering a rod or tube or reducing its diameter by any of several methods, such as forging, squeezing, or hammering. Also known as cressing.

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.
