Abstract
Glass molding press (GMP) process has emerged as a promising technology to fabricate aspherical glass lens in mass production. The quality of the molded glass lens mainly depends on the transferability of GMP process. In this paper, temperature rise during heating and material flow during the deformation of the glass ball in GMP process were simulated by the finite element method (FEM), and the stress and strain distributions were illustrated. With that, the deformation of the molds was calculated and the countermeasures to prolong the service life of the molds are proposed.
