What material is the front lower grille frame made of
The material of the front lower grille frame is usually modified plastic (such as modified ASA, ABS, PC/ABS, etc.), which combines lightweight, weather resistance and processing performance.
Material properties
Youdaoplaceholder0 modified ASA : Made by blending acrylonitrile butadiene-styrene copolymer (ABS) with acrylate copolymer (ASA), it features high weather resistance, UV resistance and aging resistance, making it suitable for long-term outdoor exposure to intense sunlight.
Youdaoplaceholder0 ABS : Engineering plastic, with low water absorption and strong impact resistance, suitable for electroplating processing of complex shapes, and commonly found in components with high appearance requirements.
Youdaoplaceholder0 PC/ABS : an alloy of polycarbonate and ABS, featuring high transparency, high strength and heat resistance, suitable for complex structural components.
Functional requirements
The front lower grille should meet the following requirements:
Youdaoplaceholder0 Weather resistance : resistant to ultraviolet rays, high temperatures (such as intense summer sun exposure) and low temperatures (such as ice formation in winter)
Youdaoplaceholder0 processability : It is convenient to be formed into complex shapes through molds
Youdaoplaceholder0 Lightweighting : reducing vehicle wind resistance and fuel consumption
Youdaoplaceholder0 Safety : Prevent foreign objects from entering the engine compartment while maintaining an aesthetic appearance
The front lower grille frame (usually referring to the air intake grille) is a key component at the front of a car, and its main functions are as follows:
Engine intake and cooling
Provide fresh air for the engine to ensure complete fuel combustion and enhance power performance; At the same time, it guides cold air into the engine compartment to help dissipate heat and maintain the optimal operating temperature of the engine. In winter, the speed of warming up the car can be accelerated and the efficiency of the warm air can be improved.
Protective function
Block the flying stones, sand and other foreign objects during driving to prevent them from hitting key components such as the engine and radiator, and reduce maintenance costs.
Ventilation and heat dissipation assistance
Provide air intake channels for the air conditioning system to ensure temperature regulation inside the vehicle. At the same time, it assists in the heat dissipation of the water tank and maintains the normal operation of the cooling system.
Exterior decoration
Different design styles (such as mesh, strip, honeycomb, etc.) can highlight the brand characteristics and personality of a vehicle and become the core elements of the front face design.
Faults of the front lower grille frame are usually related to the grille partition, mainly manifested as loose grille rakes, clogged grille bars or abnormal control systems. The following are the specific reasons and solutions:
Common causes
Youdaoplaceholder0 Loose rake : The gap between the rake and the grid surface is too large, resulting in ineffective filtration. The adjusting spring needs to be adjusted to make the rake closely adhere to the grid surface.
Youdaoplaceholder0 water level gauge failure : Abnormal water level detection causes system misjudgment. The water level gauge needs to be inspected, repaired or replaced.
Youdaoplaceholder0 bar clogging : Large solid particles clog, causing poor water flow. Foreign objects between the bars need to be cleared.
Youdaoplaceholder0 Abnormal water pressure : When the vehicle is wading through water, the water pressure causes the partition to act out of command. It is necessary to check the matching of the motor control system.
Solution
Adjust the rake spring or remove foreign objects
Inspect and repair the water level gauge or replace faulty components
Regularly clean the grille to prevent clogging
Avoid driving through water or install protective devices
It is recommended to contact a professional institution for inspection to avoid engine failure caused by abnormal cooling system.
