The 91510-3 is a crimp tooling component used in wire termination and barrel crimping applications within electrical connector assembly. This tooling is designed to achieve precise crimp height (CH) and crimp width (CW) control to maintain proper Area Index (AI) performance, typically targeting an 80% AI design point. The component operates with critical dimensional tolerances, including crimp height tolerances of ±0.002 in and requires careful control of anvil-to-crimper clearance to prevent excessive flash formation. The tooling experiences high shear loading and moderate shock during the plastic deformation and extrusion of terminal barrels. Proper material selection and dimensional control are essential for maintaining consistent crimp quality, pull test values, and production throughput in high-volume termination processes.
