Abstract:
A two-part reusable mask to protect objects to be plated. The mask can be used for painting, chemical treatment or other treatments. By adjusting the shape of the mask, any object can be plated. In the case of coins or medallions, a two sided mask is formed. For use with coins, the coin is laid on a piece of glass. A dam is formed around the coin. A quantity of ultraviolet-sensitive liquid polymer is poured on and around the coin. The dam is covered with another piece of glass and the mold is clamped and cured. The mold is removed and an exact copy of the coin is left in the rubber. The rubber mask is then placed on a hard surface and the areas to be plated are cut out. After the mask is cut out, it is placed back over the coin and aligned. A piece of clear, hard plastic is bonded to the rubber using a clear adhesive. After the glue is cured, the plastic is cut out to match the corresponding pattern cut in the rubber.
