• This paper deals with the separation behavior of a press-molded glassware from the pressing mold surface. Since the separation of the glass from a mold surface affects the transcription of the glass shape from the mold, it is desirable to control the separation behavior in the practical press-molding of glassware. In this study, paying attention to that the separation or sticking of the glass was mainly influenced by thermal pressing conditions in practical molding, separation forces during the demolding process between glass and mold were measured under various pressing conditions. The results showed that, under the certain conditions, the glass stuck on the pressing surface of the mold even after the mold was removed from the pressed glass, and that the separation (sticking) force increased with rising initial temperature of glass and mold, increasing the pressing pressure, and with elongation of pressing duration. In order to translate the obtained results, the separation forces were correlated to the interface temperature between glass and mold at the end of pressing process. The correlation showed that the sticking force became evident when the interface temperature exceeded a certain temperature for whole experiments. Under the experimental conditions, the threshold temperature was about 660℃, and was slightly lower than the softening temperature of the glass used. From the results, it is concluded that the separation behavior of a press-molded glassware is dominated by the interface temperature between glass and mold at the end of pressing process.
