Why is it recommended to replace bumpers during repairs nowadays?

[FranciscoLynn]

Because it mainly depends on the extent of damage to the bumper, which the repair technician will make a clear judgment on. If the front bumper is cracked, the decision to repair or replace it can be based on the size of the crack. If the crack is relatively small, it can be welded and repaired. If it exceeds the repair standard, replacement is necessary. Below is relevant information: 1. Introduction: The car bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear of the vehicle body. Many years ago, front and rear car bumpers were made of steel plates stamped into channel steel and riveted or welded to the frame longitudinal beams. 2. Function of the bumper: The bumper primarily serves as a buffer to absorb and alleviate external impacts. During low-speed collisions, the bumper can reduce the impact force and protect the vehicle body. If the damaged area of the bumper is large, repair is unnecessary, as it would not provide the intended buffering effect even if repaired.
