The car bumper is an indispensable component of the vehicle safety system, whose core function is to protect the vehicle body and occupants through a hierarchical energy-absorbing structure. Modern bumpers adopt a three-layer design consisting of an engineering plastic outer panel, a polyurethane buffer layer, and a high-strength steel crossbeam. They can absorb energy through plastic deformation in low-speed collisions at 4-15 km/h, effectively reducing repair costs and protecting pedestrians' legs. Additionally, bumpers contribute to aerodynamic optimization. For instance, models like the Xpeng P7 achieve a drag coefficient as low as 0.236 Cd through airflow channel designs, improving driving stability. With technological advancements, bumpers have evolved from passive protection components into intelligent safety modules integrating millimeter-wave radars and cameras, enabling active safety features such as automatic emergency braking. Regarding materials, the widespread use of ABS engineering plastics and polypropylene has reduced bumper weight by over 60% compared to traditional metals while maintaining impact resistance and weather resistance. For Malaysian consumers, selecting original equipment manufacturer (OEM) specification bumpers is particularly crucial as they ensure precise alignment with vehicle body dimensions, proper heat dissipation channels, and compliant collision buffer zones. Professional installation further guarantees sensor calibration accuracy and structural integrity.
