A technique for controlling and optimizing injection molding parameters by numerical simulation is proposed. Using this method for an optical element designed for roadway lighting, multilens molding quality criteria have been defined. Optimal parameters for lens manufacturing have been determined. Based on these parameters, a polycarbonate multilens has been made with an absolute tolerance equal to 0.01 mm.
