Optimization of process parameters of GMP for 3D ultrathin glass based on cuckoo search algorithm

Abstract

From the current development trend of mobile phone industry, 3D curved glass screen is undoubtedly the hot spot of the industry, and glass molding processing (GMP) is the main method of 3D curved glass manufacturing at present. 3D curved glass is a kind of curved glass which is formed by heating, softening, and annealing process in the mold. In GMP, process parameters not only determine the efficiency and quality of curved glass processing, but also affect the emission of CO2. Moreover, there is no definite mathematical model for the influence of these involved process parameters on the effect of hot bending. In this paper, the GMP experiment of the finished glass is carried out, and the relationship between the processing parameters and the processing quality of the finished glass is summarized. Furthermore, the experimental data is analyzed to investigate the influence of process parameters on performances of GMP. By cuckoo search algorithm method, the parameters of GMP are optimized.

Study of Heat Transfer Strategy of Metal Heating/Conduction Plates for Energy Efficiency of Large-Sized Automotive Glass Molding Process

“…To improve heat transfer efficiencies, Li et al [14] proposed a low-energy consumption, short-cycle, and high-precision temperature control heating system for hot press forming to improve temperature control accuracy and process quality. Ming et al [15][16][17] simulated and tested the energy use of different heating methods for smartphone casing. Under optimal process parametric conditions, the model decreased the expected energy consumption from 614 kJ to 594.4 kJ, a decrease of 3.19%.…”
