91521-3 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 ensuring proper electrical and mechanical connection quality. Key dimensional parameters include 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 extrusion process. Proper dimensional control and material selection are essential to minimize flash generation and maintain consistent crimp quality across production runs.
