Quartz Glass Molding by Precision Glass Molding Method

Abstract

Demand for various glass-parts is now increasing rapidly as information technology is developed. There are several methods for processing glass-parts, and Precision Glass Molding Method is one of the best processing methods for making precise parts and lowering the price of glass-parts for mass-producing. Recently, quartz glass is studied for new glass-parts materials. But molding of quartz glass is difficult because softening temperature of quartz glass is very high and there is little information about molding of quartz glass. We researched about quartz glass molding and developed Glass Molding Machine for molding quartz glass. This paper describes that how to mold quartz glass, what is important for quartz glass molding, and analyzing of mobility of glass and heat expansion of mold in molding temperature.
