Abstract
A method of requalifying a die after storage under this disclosure could be said to include the steps of running production parts on a die, stopping production for a period of time, taking a pre-storage 3D scan of the die, storing the die for a period of time, taking a post storage 3D scan of the die, comparing the post storage 3D scan information to the pre-storage 3D scan information, and requalifying the die for use in production should the post storage 3D scan be found to be sufficiently close to the pre-storage 3D scan.
