New approaches on reusing dies (Decoating / repolishing / recoating)
Summary
PVD coating of dies is an already well known technique to increase die life of minting tools. It is common to use Cr-based coating materials, due to it positive behaviour on striking coins.
However, one of the biggest challenges was always a sustainable removal of Cr-Coated dies, due to the severe environmental rules in regards of chemical decoatings and potential residuals of Cr 6 / Hexavalent Chrome.
