ABSTRACT:
A low cost tooling replication technique for producing glass pressing tools capable of producing precision complex optical surfaces is disclosed. A master glass pressing tool surface is first passivated and plated with nickel or other suitable material to a thickness sufficient to give the plated material some mechanical strength. The plated material is separated from the master glass pressing tool surface to reveal a negative of the master glass pressing tool surface. This negative surface is passivated and plated with nickel or other suitable material to a thickness sufficient to give the plated material some mechanical strength. The plated material is separated from the negative surface to reveal a replica of the master glass pressing tool surface. A plurality of platings may be made on the negative surface to produce a plurality of replicated master glass pressing surfaces. The replicated master glass pressing surfaces are provided with a backer. The backer may be electro-plated copper, for example, to provide good heat conduction from the glass pressing surface. The backer is attached to a flange for mounting in a press.
