ABSTRACT:
A three-dimensional electroformed shell for a mold consists of a three-dimensional thin-walled body, and an electroformed coating deposited on it. The coating may, or may not close the base holes of the thin-walled body completely. If it does not close the base holes completely, the shell has a multiplicity of apertures. A process for manufacturing the shell is also disclosed.
