采用非等温玻璃模压机（NGMP）制备非球面透镜，并与传统等温玻璃模压机（IGMP）进行对比，通过实验和有限元模拟研究了非等温玻璃模压机的特性。对两种工艺的非球面加工周期、形面精度、表面粗糙度、应力应变分布等进行了测试和比较。实验结果和模拟结果表明，NGMP是提高成型效率、延长模具使用寿命的有效途径。
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.
