GRAMM Galvanoforming technology is used to create precise and pure gold copings of uniform thickness from .20 mm – .30 mm. Using this technique, the dies are duplicated and an insulated copper electrode is attached within 1 mm of the prepared margin. A silver electroconductive spacer is then painted over the die to the margin area and is extended to contact the previously attached electrode. The electrode is attached to the galvanoforming equipment and the die is submerged in an electrolyte bath. The duration of the cycle as well as the desired current (mA) are programmed into the machine according to the overall surface area of the preparation. The completion of the cycle yields 99.99% pure gold copings of consistent thickness.
