What mechanical process involves shaping metal at ambient temperatures?

Swaging is the mechanical process that involves shaping metal at ambient temperatures through deformation. This technique typically uses a die to compress or reduce the diameter of the metal, allowing for the creation of specific shapes and sizes without the need for heating.

In swaging, tools work together to apply pressure to the metal, which can lead to various outcomes, such as tapering ends or creating intricate designs. Since the process occurs at room temperature, it helps preserve the integrity and characteristics of the metal being manipulated.

Though other processes like forging, welding, and bending also alter metals, they either involve high temperatures (as with forging and welding) or may not significantly shape the material (as seen in bending). Therefore, swaging stands out for its cold-working technique that effectively reshapes metal while maintaining its ambient qualities.
