Abstract
A method includes placing a conductive mold in a first bath of electroforming solution, the solution including metal and having a selected temperature. A current is provided to the electroforming solution so that metal deposits onto the mold, thereby forming an electroformed element on the mold, the electroformed element and the mold being a composite assembly. The method further includes removing the composite assembly from the electroforming solution and transferring the composite assembly to a second bath having the same selected temperature. Thereafter, the electroformed element is separated from the mold while the composite assembly is in the second bath.
