In recent years, with the rapid development of new energy vehicles, the automotive industry has put forward higher requirements for auto parts. In order to meet the demand for lightweight, manufacturers use high-strength materials and optimize the design to reduce weight while ensuring the stability and durability of the structure. In addition, the car battery housing with good sealing and protection is also key to prevent the impact of the external environment on the components and extend the service life. In terms of heat dissipation performance, the heat dissipation effect of the components is greatly enhanced, so that the car can still maintain stable performance under high load. Such innovation not only improves the overall performance of the car, but also promotes the entire industry to a higher technical level. In the field of sheet metal processing of auto parts, Xinzhe has always actively explored and innovated new technologies on the basis of energy saving and environmental protection, and continuously optimized and improved product performance.
