METHOD FOR PRODUCING GLASS GOB, METHOD FOR PRODUCING GLASS MOLDED BODY AND APPARATUS FOR PRODUCING GLASS GOB AND APPARATUS FOR PRODUCING GLASS MOLDED BODY

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing glass gob or a glass molded body having small surface roughness while suppressing the occurrence of the accumulation of a gas even when a lower mold having small unevenness on the surface is used.;SOLUTION: The flow of the gas flowing from the center of a receiving surface to the outer periphery is formed above the receiving surface of the lower mold. In the formation of the gas flow, a molten glass droplet is dropped from the dropping nozzle and received on the lower mold.;COPYRIGHT: (C)2010,JPO&INPIT
