What are the impacts of rear-end collision and subsequent cutting on a vehicle?

[ColinMarie]

A rear-end collision typically has minimal impact on the powertrain and mechanical systems of a vehicle. However, if the main frame is damaged, it could significantly affect the vehicle's safety. Additionally, any vehicle that has undergone sheet metal repair or cutting will experience depreciation, resulting in a substantial price reduction when sold as a used car. Below is additional information: 1. Sheet Metal Work: Sheet metal fabrication is a comprehensive cold-working process for thin metal sheets (usually under 6mm), including shearing, punching, bending, welding, riveting, mold forming, and surface treatment. A notable characteristic is the uniform thickness of the same part. 2. Advantages: Most sheet metal components are made from thin metal sheets and tubes. Due to their lightweight, high strength and rigidity, ability to form complex shapes, low material consumption, and smooth surfaces, they are widely used in daily life and industrial production. The finished products are extensively applied in the bodies of cars and trucks.
