Abstract
A method for processing a curved plastic panel is to first form a hard coating layer, an optical function layer, and a printing layer on a flat plastic substrate, and then cut it into a predetermined shape, and then use a hot pressing and curving device to perform a hot pressing and curving process to the flat plastic substrate in order to make it becoming a curved plastic substrate. The hot pressing and curving device can simultaneously perform hot pressing during the heating process, and has the functions of real-time monitoring of the local temperature and the local curvature forming state, and then feedback to the local heating and curvature forming mechanism for adjustments. The monitoring of temperature and curvature can be divided into multiple stages, which can be monitored stage by stage and adjusted for heating or curvature forming to improve production yield.
