Excuse me, what material is used for headlights? Please elaborate, hehe, including reflective net, lampshade and lamp shell. It would be better if you could talk about the properties of the materials, hehe. The main material of headlights: lampshade PC, generally only UV-resistant materials from GE and Bayer can be used. After injection molding, the surface needs UV curing to improve the surface hardness. Shell PP-T40, good toughness. BMC for reflector is a thermosetting plastic with good temperature resistance.

The main material of taillights: PMMA lampshade. Compared with PC, it has higher surface hardness and better wear resistance, but the disadvantage is that the temperature resistance is about 1 10C. The shell PC+ABS or ABS is made of alloy material, because PC has higher temperature resistance and certain rigidity than ABS. Tail lamp reflector is generally made directly on the shell.
