Torrington’s rotary swaging machine is used to form a circular cross-section material into a smaller circular cross-section material.
​
Reduction starts from one end of the part and occurs over a specific length or the entire length of the part. We offer a vast range of different sizes of rotary swaging machines to accomodate multiple material & diameters (1/16″ to 3.5″)
Torrington’s Die-closing (DC) swaging machine is also used to form a circular cross-section material into a smaller circular cross-section material.
​
However, a special mechanism allows the reduction to happen anywhere on the part, without having to start on one end of the part. It is also used for creating mechanical assemblies.
Torrington’s stationary-spindle swaging machine is used to obtain a formed part with a non-circular cross-section.
​
The part may or may not be of circular cross-section before forming. Reduction happens from one end of the part for a determined length, or the entire part can be swaged.

A swaging machine converts kinetic energy into forming forces that are applied radially by the dies to the workpiece with short strokes at a high frequency.
Most materials can be swaged at room temperature ("cold swaging") and without any lubrication. For materials having high tensile stength, it is recommended that the reduction be done at elevated temperatures. Hot swaging is useful for very steep tapers on both tubular and solid work and where long tapers and large reductions are required.
Â
Some metals such as tungsten and certain brazing materials can only be swaged hot. Special machines with water-cooled heads and components made from heat-resistant alloys are available for hot swaging.
Swaging machines
« Swaging » is a metal forming method by which the cross section of a tube, bar or wire is reduced to another specific cross-section of predetermined shape and dimension. Torrington manufactures industrial swaging machines including rotary swaging machines, die-closing swaging machines and stationary spindle swaging machines for precision metal forming applications
