Crimping is joining two pieces of metal or other malleable material by deforming one or both of them to hold the other. The bend or deformity is called the crimp.
Crimping is most extensively used in metalworking. It is not generally used of specialised connectors that are designed to be deformed, but only of workpieces. Crimping is commonly used to join bullets to their cartridge cases, and for rapid but lasting electrical connectors. Because it can be a cold-working technique, crimping can also be used to form a strong bond between the workpiece and a non-metallic component. Sometimes, a similar deformity created for reasons other than forming a join may also be called a crimp [1][2][3][4].
