SWAGING - Tube Swaging SWAGING - Tube Swaging

Swaging is a process that is used to reduce or increase the diameter of tubes. A swaged piece created by placing the tube inside a die that applies compressive force by hammering radially.                             

04/10/23 19

SWAGING - Tube SwagingSWAGING - Tube Swaging

Swaging can be further expanded by placing a mandrel inside the tube and applying radial compressive forces on the outer diameter. Thus, through the swage process, the inner tube diameter can be a different shape, for example a hexagon, and the outer is still circular.
