Development of a Vacuum Melt Press for Fiber Optic Plate

Based on hydraulic proportional feedback system and sensor testing technique, an automatic melt press for FOP fabrication was developed to improve the low control accuracy and reproducibility of conventional melt presses to fabricate fiber optic plates (FOP). Describes its working principle, process flow and structural characteristics, especially the working principle of its hydraulic control system that is the core in machine reforming. Experiment results showed that the melt press we developed is highly automatic, and its control accuracy of technological parameters is proved not lower than other advanced similar domestic/foreign systems, i.e., the control accuracies of vacuum degree, temperature and pressure are ± 2 Pa, ± 0.1°C and ± 1%, respectively. A new means was thus provided for R&;D of FOP fabrication.
