利用一种专门研制的配有高灵敏度测力传感器和压力传感器的成型装置，对氧化物玻璃从模具中的脱模行为进行了实验分析。脱模点和脱模力随施加在压制轴上的拉力和冷却速度的增大而增大。特别是当脱模点位于玻璃化转变温度附近时，脱模力受冷却速率的影响更大。这些结果为高精度玻璃模压和玻璃压印工艺提供了有益的指导。
Demolding behavior of oxide glasses from molds was experimentally analyzed using a specially developed molding set up equipped with highly sensitive load cell and servomotor. The demolding point and the demolding force were apt to increase with the tensile force applied to the pressing axis, and also to the cooling rate. Especially the demolding force was strongly affected by the cooling rate when the demolding point was located near the glass transition temperature region. These results offer a useful direction for highly accurate glass-molding and glass-imprint processes.
