| 摘要 |
The present invention relates to a process for producing a mold for glass press molding which comprises adopting, in the ion plating method to form an i-carbon film, a given hydrocarbon, given voltages, given temperature conditions, etc. According to the process, there could be obtained a mold for glass press molding, having an i-carbon film superior in adhesion to mold base, hardness, lubricity, etc. In this mold for glass press molding, the i-carbon film is less susceptible to peeling and glass releasability is good even after many times of press molding. Therefore, the mold can be used for glass press molding over a long period of time.
