Process for producing glass mold |
摘要 |
According to the present process for producing a glass mold, a base for a glass mold to be produced is subjected to a sputtering treatment using an inert gas and graphite as a target at a mold base temperature of 250 DEG -450 DEG C., and thereby is formed on the mold base a hard carbon film having excellent adhesion to the mold base and excellent hardness and being unliable to cause fusion bonding to a molded glass article produced. Accordingly, the glass mold produced according to the present process has excellent durability and excellent glass releasability.
