Abstract
A PVB film for HUD, a forming mold and a forming method thereof are presented. The accuracy error of HUD imaging achieved by the PVB film for HUD is ±0.1 mrad. The forming mold includes an upper mold and a lower mold, the two of which can form an enclosed mold cavity when clamped together, wherein protective films are disposed on inner surfaces of the upper mold and the lower mold, respectively, for supporting PVB material and preventing the PVB material from bonding with the upper mold and the lower mold, and wherein shapes of the protective films match shapes of the upper mold and the lower mold.
