Swaging

Swaging is a kind of forging process, which is commonly used in forging application. In the process of swaging, the dimensions of an item are altered using a die or dies, into which the item is forced and changed into a different shape compared to before. Swaging is a cold working process in the most time; however, in some special situation it is done as a hot working process.

As a general manufacturing process swaging may be broken up into two categories. The first category of swaging involves the workpiece being forced through a confining die to reduce its diameter, similar to the process of drawing wire. This may also be referred to as "tube swaging." The second category involves two or more dies used to hammer a round workpiece into a smaller diameter. This process is usually called "rotary swaging" or "radial forging."

Tubes may be tagged (reduced in diameter to enable the tube to be initially fed through the die to then be pulled from the other side) using a rotary swager, which allows them to be drawn on a draw bench. Swaging is normally the method of choice for precious metals since there is no loss of material in the process.
