What is the difference between Crimping and Swaging?

What exactly is the difference between crimping and swaging?

The basic difference between the two processes is that the swaging process starts at the end closest to the hose and begins reducing the ferrule moving toward the fitting, stopping about ¾ of the way up the ferrule creating a bell area creating a pocket for the excess hose to flow into. “In swaging, a machine pushes a fitting and ferrule through a fixed split die bed to reduce the OD of the ferrule, compressing the hose into the stem serrations, while a crimping machine has any number of segment dies that close around the ferrule or sleeve and reducing it to a predetermined OD. The crimping process changes the shape of the entire circumference and length simultaneously. Crimping takes a lot more force (muscle) to reduce heavy wall ferrules all at once,
