Abstract

Nonisothermal glass molding press (NGMP) was proposed to fabricate aspherical lenses, and its characteristics were studied by both experiments and finite element method (FEM) simulations in comparison with the traditional isothermal glass molding press (IGMP). The cycle time, form accuracy, surface roughness, stress/strain distributions of the aspherical lenses made by IGMP and NGMP were examined and compared. Experimental results and simulation results show that NGMP is an effective way to improve the molding efficiency and prolong the service life of the molding dies.
