The 91391-2 is a bottoming die component used in TE Connectivity's crimp tooling systems to guarantee proper crimp force application during wire termination. This die is calibrated to work within specified handle force parameters and crimp height tolerances to ensure consistent terminal compression and cross-sectional area reduction of both wire and terminal. The component is part of TE's CERTI-CRIMP tool line, which includes certification documentation of critical crimp area dimensions and handle pressure settings. The 91391-2 operates within a handle force range of 40–47 lbs and maintains crimp height specifications between 38.18 and 498 units, ensuring repeatable crimping results. This bottoming die is essential for maintaining long-term consistency in crimping production, delivering specified tensile strength, mechanical stability, and electrical conductivity in crimped connections. It is commonly used in wire processing applications where reliable, certified crimp tooling is required for quality assurance and manufacturing compliance.
