A crimper and anvil have different functional requirements. Both need to withstand high loads and moderate impacts. However, a crimper is actually an aggressive forming tool. It must withstand high shear loads, which shear The load is due to the frictional load that occurs when the terminal barrel slides along the surface of the crimper during forming, and then completes the termination as the barrel terminal plastically deforms and squeezes. The anvil experiences some of the same conditions, but Severity is low.
Special material properties related to the crimping process include toughness to withstand the shocks created during the crimping process and sufficient wear resistance to maintain dimensional tolerances.
