4-1579001-6 is a crimp tooling component used in electrical terminal crimping processes. The tooling is designed to achieve precise crimp height (CH) and crimp width (CW) control to maintain an Area Index (AI) of approximately 80%, which is critical for proper electrical and mechanical performance. Key dimensional parameters include a nominal crimp height of 0.073 inches, crimp width of 0.110 inches, crimper leg taper of 3.0 degrees, and anvil width of 0.109 inches, with a nominal anvil-to-crimper clearance of 0.005 inches. The tooling components, particularly the wire crimper and anvil, are manufactured from materials selected to withstand high loads, moderate shock, and the shear loading generated during the terminal barrel forming and plastic deformation process. This crimp tooling is essential for maintaining production quality metrics such as crimp symmetry, pull test values, and consistent lead termination rates in high-volume connector assembly operations.
