Crimpers - Crimp Heads, Die SetsCrimpers are tools that are used to connect two pieces of metal by deforming one or both of them, typically by pressing them together with a special device called a crimp head or die set. Crimp heads and die sets are the interchangeable parts of a crimper that are used to apply the necessary force to create the connection. Crimp heads and die sets come in a variety of sizes and shapes, depending on the type and size of the connectors being used. They are typically made of hardened steel or other durable materials to withstand the forces involved in crimping. Crimpers are commonly used in the field of electrical and electronic engineering, where they are used to create connections between wires, cables, and other conductive materials.
