ABSTRACT:
In a process for metal replication of Glass dies, the cleaned die is secured in a cavity of a fixture, and a thin masking diaphragm is placed over the die and fixture to expose only the die surface to be replicated. A vacuum is applied through passages in the fixture to secure the diaphragm. The diaphragm-die surface is silvered to render it conductive, and the fixture is immersed in an electroplating bath. After sufficient buildup of electrodeposited material, the fixture is removed from the bath. The metal replica is then removed from the die to reveal a surface which includes an exact replica of the glass die master.
