91544-1 is a bottoming die component designed for use with TE Connectivity's CERTI-CRIMP hand tool crimping systems to ensure proper and repeatable crimp force application. The bottoming die is a critical element in maintaining consistent crimp performance by controlling the compression and reduction of the cross-sectional area of both wire and terminal during the crimping process. Based on the certification documentation, the tool operates with a handle force range of 40 to 47 lbs and achieves a crimp height between 38.18 and 498 units after crimping. Regular maintenance and certification on an 8-month cycle or every 1,000 cycles ensures that the bottoming die continues to produce crimp quality that meets specifications for tensile strength, mechanical stability, and electrical conductivity. This component is essential for applications requiring reliable terminal crimping in wire processing and connectivity solutions.
