The 48131 is a bottoming die assembly used in crimp tooling systems to ensure proper and repeatable crimp force application during terminal crimping operations. The die is designed to work within a handle force range of 40–47 lbs and produces a crimp height between 38.18 and 498 units (as-received) and 452–389 units (after crimp), ensuring consistent mechanical stability and electrical conductivity. This tooling component is part of TE Connectivity's application tooling portfolio and requires recertification every 8 months or 1,000 cycles to maintain crimp quality standards. The bottoming die is essential for achieving specified tensile strength and proper wire-to-terminal compression in high-volume crimping production environments.
