Car bumpers are made of plastic material. The method and precautions for replacing a bumper are as follows: Method for replacing a bumper: Remove the bumper cover, clips, screws, and bolts. Pull the bumper in the wheel arch area, remove the bumper from the side, and replace it with a bumper of the same model. Precautions for replacing a bumper: Pay attention to the model. For general brand vehicles, original parts must be configured to ensure a perfect fit. Additionally, there should be no color difference. When drilling or disassembling the energy-absorbing device, safety must be prioritized by wearing reliable goggles. When replacing an energy-absorbing bumper, the energy-absorbing device must be tested.

I noticed that most modern car bumpers are made of plastic, like commonly used polypropylene, which is both flexible and lightweight. I remember driving older cars with metal bumpers that were prone to rust and deformation, making repairs troublesome and costly. Now, with plastic bumpers, there are many benefits. For example, in minor collisions, they can absorb impact forces, protecting both the vehicle body and pedestrians, while also reducing vehicle weight to help save fuel. Last time I accidentally scraped against a pole, the bumper only had scratches, and I fixed it with a heat gun without spending much money. In short, plastic bumpers have become mainstream—simple to manufacture, environmentally friendly, with high recyclability, offering both safety and affordability.

From an automotive engineering perspective, bumper materials are primarily plastics such as ABS or TPO, designed with lightweight and impact resistance in mind. Plastic bumpers are lighter than metal, easier to assemble, and more effective in absorbing deformation during crash tests—especially in low-speed collisions where they minimize damage. My material research shows plastics also resist corrosion and rust, extending service life. While some express strength concerns, modern manufacturing techniques have reinforced their structure. Though specialty vehicles occasionally use composites, household cars predominantly feature plastic bumpers—cost-effective, eco-friendly, and simpler to repair via welding or full replacement, while delivering smoother driving experiences.

I often deal with bumper repairs, mostly made of plastic, which is easy to fix. Small dents or cracks can be repaired with professional heat tools and repainted to look like new, costing only a few dozen to a hundred yuan. Metal bumpers don't have this advantage. Plastic is lightweight, quick to remove and install, saving time, and minor bumps in daily driving are less concerning. I recommend car owners choose models with plastic bumpers—lower maintenance costs, longer lifespan, and even DIY fixes for minor issues. Practical and hassle-free.
