MOLDING MOLD FOR PRECISION PRESS, METHOD FOR PRODUCING THE MOLD AND METHOD FOR PRODUCING GLASS

摘要

PROBLEM TO BE SOLVED: To provide a method for producing glass, capable of preventing surface defect of press molding product caused by a reaction product between mold release films and glass when a preform comprising glass containing lead oxide or titanium oxide is pressed by a molding mold for precision press by supplying the mold release films having low reactivity to glass when the preform comprising the glass containing lead oxide or titanium oxide is pressed by the molding mold for precision. ;SOLUTION: This molding mold for precision press improves hardness of the mold release film by forming the mold release films 2 and 4 composed of Au on molding bases 1 and 3 and irradiating the surfaces of the mold release films with Ar ion.;COPYRIGHT: (C)2001,JPO
