Press molding die and method of manufacturing the same, and magnetic disk glass substrate |
摘要 |
A press molding die for a glass material is manufactured by forming an organic compound layer composed of an organic compound having a pyrolysis temperature on the press molding surface of the press molding die; and converting the organic compound layer into a mold release layer by heating to a temperature of at least the pyrolysis temperature of the organic compound. The mold release layer is thus inexpensively provided on the press molding surface, secures excellent releasability of a glass material from the press molding surface of the die, and does not cause unevenness of the press molding surface even upon repeatedly carrying out press molding.
