The invention discloses a production process of an automobile lamp shade. The production process includes the following steps that S1, selected materials are dried; S2, melting and cooling are conducted; S3, laser cleaning is conducted; S4, the outer surface is treated; S5, outer surface curing is conducted; and S6, the inner surface is treated. According to the production process of the automobile lamp shade, an anti-dazzle coating film coating is coated on the inner surface of a lamp shade semi-finished product, the anti-dazzle coating film coating is a PTFE thin film coating, and PTFE has the advantages of high humidity, high hardness, scratch resistance, long service life and the like, and can further insulate water vapor, infrared rays and ultraviolet rays;and invasion of the ultraviolet rays and theinfrared rays can be effectively prevented when coating the PTFE thin film coating on the inner surface of the lamp shade semi-finished product, the anti-dazzle coating film coating iscoated on the inner side face of the lamp shade, radiation of the ultraviolet rays and the infrared rays can be eliminated, the glare phenomenon can be avoided, and eyes of a drivercan be effectivelyprotected.
