Comprehensive Guide To Swaging Machines

Swaging machines are used to increase or reduce the diameter of rods or tubes. It does it by forming a workpiece forcing it into a die and creating new materials with varied dimensions. To reduce the diameter of the metal rod or tube the metal is placed inside the machine and is hammered to get desired results.

The resultant shape of the metal is deformed, however; there is no loss of material in the process. Since there is no loss of material, these machines are used widely in processes involving precious metals.

These machines form a part of a larger commonly known process, which is known as cold forming processes. Although, these machines are sometimes used for the hot forming process in some rare situations.


There are mainly two categories. One is rotary swaging and the other is tube swaging. The tube swaging machines are similar in process to drawing wire. These machines are also adjustable, as they can be expanded for various types of diameters of rods and tubes.

Cold tube process is most common in aluminum, thin steel, and copper industry. The radial swaging is also a cold working process that reduces the diameter and creates a tapered end on a round work-piece; it is also useful to add a point on the work-piece. The machine is able to hammer up to 2000 times a minute.

The motor rotates the main components, which are located inside a cage containing the rollers and the dies are mounted in such a way that they are on top of machines spindle. The rotary swaging can produce internal shapes inside the tube. It uses a mandrel to operate as long as the shape of the tube has a cross-section that is equally present throughout its length.


The most common application of these machines is in attaching cables or pipes with extra fittings. Firearms and ammunition are also created through this process. Pipe flaring and sawmilling also uses this type of industrial process. Many of the automotive components are produced through this process. The rubber industry also uses this machine to produce various kinds of materials.

From aerospace applications to agricultural machinery, these machines have a crucial part to play. Other places where these machines are used extensively are medical devices, measurement and adjustment devices, tool construction and optics, brazing and welding devices, manufacture of jewelry, fixtures, and metal joining. Apart from these, there are several other uses of this machine in various
