The plastic front bumper consists of three parts, namely the outer panel, the buffer material, and the cross member. The raw materials of the outer plate and the buffer material are all plastic, the beam is stamped into a U-shaped groove from a cold-rolled sheet, and the thickness of the cold-rolled sheet is about 1.5 mm.
