MOLD FOR PRESSING AND MOLDED GLASS SUBSTRATE FOR COMPUTER MEMORY BY USING IT

摘要

A mold for pressing molded glass plates where the desired flatness of the shaped surface of the metallic mold-made of super-hard material- is achieved by carbon coating. Before the carbon coating is applied, ions are injected into the mold surface. This increases the adhesiveness of the carbon coating resulting in an increased usable life for the mold.
