What to do if there is a crack in the front bumper?
2 Answers
A crack in the front bumper can be repaired. Using a professional plastic welding gun, the plastic welding rod and the surface of the film are melted and bonded by heating; after repairing the crack, a paint touch-up is required, and then it should be dried. Additional Information: 1. Function of the bumper: The car bumper (anti-collision beam) is located in most areas at the front and rear of the car. It is designed to prevent damage to the vehicle's safety system caused by external impacts and has the ability to reduce injuries to passengers during high-speed collisions. 2. Material of the bumper: The plastic bumper consists of three parts: the outer panel, the buffer material, and the crossbeam. The outer panel and buffer material are made of plastic, while the crossbeam is formed by stamping cold-rolled thin plates about 1.5 mm thick into a U-shaped groove. The outer panel and buffer material are attached to the crossbeam, which is connected to the car frame's longitudinal beams with screws and can be easily removed.
I encountered the same issue last month—my front bumper had a crack from who-knows-when. Though it wasn’t obvious, it nagged at me. I worried water might seep in, causing rust and internal damage, which would be a real headache. As a temporary fix, I used strong double-sided tape to seal the crack from the inside, preventing further widening from driving vibrations. Over the weekend, I took it to a repair shop. The mechanics inspected it and said the crack was short enough to be fixed with professional plastic welding tools for just a few hundred yuan. If it had been longer, they’d have had to replace the entire bumper, which would’ve cost significantly more. Addressing it promptly restored the car’s appearance and saved both hassle and expense. Lesson learned: be extra careful when parking or reversing to avoid scratches, and fix minor damage early to prevent bigger problems.
