Swaging is the forming method of reducing the cross section of a tube, bar or wire to a specific cross-section of predetermined dimensions, resulting in an increase in length of the swaged part. This must not be confused with crimping (or segmented swaging) or pointing methods which cannot achieve the high accuracy or surface quality of the swaging process.
A swager converts kinetic energy into forming forces, applied by the dies to the workpiece with short strokes and a high frequency. The forming is thus performed by multiple impacts of the dies, applying the forming forces radially.
There are three types of swaging:
Torrington Forming Machinery offers a variety of quiet swagers that respond to OSHA, CSA and CE standards. Our quiet swagers produce less than 85 dB of noise level.
For materials having high tensile stengths, 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. Some metals such as tungsten and certain brazing materials can only be swaged hot. Special machines with water-cooled heads and components made fro heat-resistant alloys are available for hot swaging.
