发明名称 METHOD OF MANUFACTURING AN ELECTROCAST SHELL HAVING PERMEABILITY
摘要 The manufacturing method for an electroformed shell comprises; forming electroconductive layer for a pattern surface, and adhering soluble particles to the electroconductive layer, forming space between the electroconductive layer and the particle layer and a space between adjacent particles except the adhering layer between the electroconductive layer and the particle layer. Many fine drafting holes are formed on both sides of the electroformed shell utilising dissolving out of the particles from the electroformed shell.
