Abstract: The present disclosure discloses an injection molding method for fabricating a transparent device, and belongs to the technical field of material processing. The method comprises: preparing a nano-microsphere structural polymer material from a long-chain polymer material; obtaining a glass transition temperature and a viscous flow transition temperature of the nano-microsphere structural polymer material; obtaining a processing temperature of the nano-microsphere structural polymer material according to the glass transition temperature and the viscous flow transition temperature; drying the nano-microsphere structural polymer material; plasticizing the dried nano-microsphere structural polymer material according to the processing temperature; filling the plasticized nano-microsphere structural polymer material; cooling the filled nano-microsphere structural polymer material; and demolding the cooled nano-microsphere structural polymer material to form a transparent device. With the present disclosure, the technical effect that the fabricated device has high precision and no oriented optical distortion and strain birefringence is achieved.
