What is the name of the plastic plate under the front bumper
The plastic plate under the front bumper is usually called the spoiler (also known as the front spoiler or air dam), and its main function is to optimize aerodynamic performance, reduce driving resistance and prevent mud and water splashing.
Youdaoplaceholder0 Name and function
The deflector is fixed at the bottom of the bumper. Through a downward-sloping design, it guides the airflow and reduces the air pressure under the vehicle, thereby reducing the lift and air resistance during high-speed driving and improving fuel efficiency. At the same time, it can prevent the damage to the bottom of the vehicle caused by road debris, silt and water waves.
Youdaoplaceholder0 Materials and installation
Youdaoplaceholder0 Material : Polypropylene (PP) or acrylonitrile butadiene-styrene copolymer (ABS) and other engineering plastics are mostly used, which take into account both lightweight and durability.
Youdaoplaceholder0 Installation method : Fixed by clips or screws, it can be disassembled and replaced separately without the need to replace the entire bumper.
The front bumper is a safety device at the front of a car, and its main functions are as follows:
Absorb impact force
In low-speed collisions, the front bumper absorbs the impact force through deformation and elastic materials, reducing damage to the vehicle body and occupants.
Protect the vehicle body structure
When a high-speed collision occurs, the bumper works in coordination with other parts of the vehicle body to prevent severe damage to the vehicle.
Decoration and aerodynamics
The streamlined design is adopted to enhance the vehicle's aesthetic appeal while optimizing its aerodynamic performance and reducing fuel consumption.
Pedestrian protection
Some vehicle models are equipped with buffer blocks or energy-absorbing materials at the lower end of the bumper to reduce injuries when colliding with pedestrians.
When choosing to repair or replace the front bumper after it is cracked, a comprehensive judgment should be made based on the extent of the damage, the material used, and the budget: minor cracks can be repaired, while severe cracks or damage to the inner bracket are recommended for replacement.
Youdaoplaceholder0 Core decision-making factor
Youdaoplaceholder0 degree of damage .
Youdaoplaceholder0 repairable conditions : Small crack area (such as fine lines, local cracking), no structural deformation or intact inner support. Plastic welding, structural adhesive bonding or putty filling and other repair methods are preferred.
Youdaoplaceholder0 situations requiring replacement : The crack area is large (exceeding 1/3 of the bumper), the inner bracket is damaged or the metal parts are deformed. After repair, the protective performance significantly decreases. It is recommended to replace it directly.
