Should a cracked rear bumper be repaired or replaced?
1 Answers
Automobile bumpers are safety devices designed to absorb and mitigate external impacts, protecting the front and rear of the vehicle body. They provide cushioning when the car or driver experiences collision forces. With the continuous development of the automotive industry, engineering plastics are now widely used in vehicles. Today, both front and rear bumpers are made of plastic, which not only harmonizes the vehicle's overall design but also contributes to weight reduction. The decision to repair or replace depends on the extent of the bumper damage: 1. If the internal support structure of the bumper is severely damaged or cracked: Replacement is generally recommended. When replacing, it is advisable to opt for an original equipment manufacturer (OEM) bumper. Although OEM bumpers are relatively more expensive, they offer superior quality compared to aftermarket options, with better toughness and resistance to deformation under high pressure, as well as minimal color differences. Therefore, if conditions permit, choosing an OEM bumper is the best option. 2. If the bumper has only minor cracks: Welding is an option, but it is not recommended. Although plastic welding technology for bumpers is advanced, with minimal issues in color matching and strength, there are still potential safety risks after welding.
