摘　　要：精密模压技术是制造非球面红外硫系玻璃光学元件的重要方法,采用正交试验法对Ge-Se-Te硫系玻璃精密模压成型开展工艺参数优化研究,探究升温速率、冷却速率等不同工艺条件对成型质量的影响规律。结果表明:升温速率越大,模压成型破裂的比例越大,升温速率越小,模压成型雾的比例越大;冷却速率越大,模压成型破裂的比例越大,当硫系玻璃模压成型过程升温时间和降温时间均为160~200 s时,产品质量最优。Precision molding technology was an important method for manufacturing aspheric surface infrared chalcogenide glass optical elements,the orthogonal test method was used to optimize the process parameters of Ge-Se-Te chalcogenide glass precision compression molding,and it was explored that the influence of different process conditions such as temperature rise rate and cooling rate on molding quality.The results showed that the faster the heating rate was,the larger the proportion of molding rupture was,the smaller the heating rate was,the larger the proportion of compression molding fog was,and the faster the cooling rate was,the greater the proportion of molding rupture was.When the heating time and cooling time of the chalcogenide glass compression molding process were between 160 and 200 seconds,the product quality was the best.
