Underbody coating is necessary. The chassis is a crucial component that supports and mounts the car's engine and various other parts and assemblies, forming the overall shape of the vehicle, bearing the engine's power, and ensuring normal driving. Underbody coating involves spraying a 2 to 4 mm thick layer of elastic sealing material underneath the car's chassis, akin to putting a thick armor on the vehicle's underbody. The functions of underbody coating are: 1. It can effectively protect the chassis from road gravel impacts and prevent minor scraping and friction; 2. It prevents corrosion of the chassis iron plate by acids, alkalis, and salts; 3. It prevents loosening of chassis screws; 4. It reduces noise transmission during driving, enhancing driving tranquility; 5. It blocks heat conduction from the chassis iron plate, keeping the cabin warm in winter and cool in summer.

What is the Difference Between Cast Wheels and Forged Wheels?

Here are the specific differences between cast wheels and forged wheels: 1. Manufacturing process: Cast wheels are made by pouring molten aluminum into a sand mold. After cooling and solidifying, they undergo mechanical processing (deburring, surface finishing, polishing) to complete the production. Forged wheels, on the other hand, involve placing a heated and softened aluminum block into a steel mold, then using stamping to shape it. After cooling, the wheel undergoes mechanical processing. 2. Cost: The casting process is simpler and more suitable for mass production, resulting in relatively lower costs. Forging, due to its more complex procedures, incurs higher manufacturing costs. 3. Weight: During the forging process, the aluminum block undergoes continuous stamping, which makes its molecular structure very dense after forming. This allows it to withstand higher pressure, meaning that forged wheels are lighter in weight than cast wheels of the same size and strength.
