Abstract: In order to realize the precision molding of small dual aspherical chalcogenide glass lenses, the influence of the relevant process parameters on the quality of molded lenses was studied by orthogonal molding experiment. Firstly, the molding process and the PFLF7-60A multi-station molding machine were introduced, the target lens was designed according to the aspheric curve formula. Secondly, an environmentally friendly chalcogenide glass IRG205 was selected, and the relationship between the viscosity and temperature of the glass was fitted by the VFT equation, then the molding temperature was determined, and the experimental parameters of each station were also established. Finally, the orthogonal molding experiments were conducted with no-coated mold and spherical preform, the regular influence of molding process parameters such as molding temperature, pressing load and maintenance force on the lenses' molding quality(form accuracy PV, surface roughness Ra and profile deviation) were analyzed, and the optimized molding process parameters were obtained. The results have demonstrated that the values of PV for ASP1 and ASP2 are 129.2 nm and 174.8 nm, the values of Ra are 19.6 nm and 25.6 nm, and the values of profile deviation are 0.614 m and 2.682 m, respectively. The results can satisfy the requirements for high-precision applications of lenses, and provide reference and basis for the high-precision mass production of small dual aspheric chalcogenide glass lenses.
