In modern automotive manufacturing, to reduce weight and improve structural strength, the components of the engine compartment are increasingly using lightweight materials such as aluminum alloy and engineering plastics. The base of the hood bracket as the connecting point, its robustness directly affects the driving safety and structural stability of the vehicle. There are problems with stress concentration, poor sealing, and low assembly efficiency, so structural adhesion has become a better solution. Background and challenges of hood bracket bondingWith the development of lightweight cars and electrification, the design of the entire vehicle is becoming more modular and the structure of the components is more precise.
