Preparation method of front cover of head-mounted display equipment

The invention provides a preparation method of a front cover of head-mounted display equipment, which comprises the following steps: repeatedly printing more than two layers of ink in a preset area on the inner surface of a substrate, and baking and curing in an interval between two adjacent times of printing to form more than two ink printing layers; the substrate comprises a PC layer located on the inner surface of the substrate and a PMMA layer located on the outer surface of the substrate. Milling areas, located on two sides of the ink printing layer, of the PC layer to obtain a middle substrate; fixing the middle substrate in a forming mold, and softening the middle substrate by using high-temperature and pressurized gas; heating and bending the middle substrate by using a forming mold to obtain a primary cover body; the PMMA layer on the surface of the primary cover body is hardened, and a hardened layer is formed; waste materials of the primary cover body are removed, at least one front cover is obtain
