Abstract
A method of fabricating a metallic hermetic sealing cover for a container comprises plating a strip of base metal with a material comprising preponderantly a precious metal such as gold to a thickness of 40% to 90% of the ultimate required minimum surface thickness, which may be 25 to 100 microinches, preferably about 40 microinches, dividing the strip into cover elements of predetermined size, and barrel-plating such cover elements with the plating material to provide a resultant minimum thickness of surface plating substantially equal to the required miniumum thickness.
Claims5
The method of fabricating a metallic hermetic sealing cover for a container comprising:
- plating a strip of base metal with a material comprising preponderantly a precious metal to a fraction of the ultimate required minimum surface plating thickness;
- dividing said strip into cover elements of predetermined size;
- and plating said cover elements with said material to provide a resultant minimum thickness of surface plating substantially equal to the required minimum thickness.
