Abstract

In order to make 3-D glass from 2-D glass for mobile device windows, a mold is used for heat forming. In this process, the temperature of the glass is very important. However, measuring the temperature of the glass inside the mold is very difficult owing to the mold structure and the high temperature. The purpose of this study is to measure the temperature inside the mold by using Process Temperature Control Rings (PTCR) and to compensate for temperature differences in the heat forming machine and inside the mold. The measuring method uses the ceramic material's shrinkage characteristics, which makes it possible to measure the temperature inside the mold at various locations.
