With the increasing prevalence of urban development, smart homes, and surveillance systems, the requirements for electronic device casings for weather resistance, corrosion resistance, and aesthetically pleasing design are continuously increasing. Aluminum alloy, due to its excellent thermal conductivity, aesthetic appearance, and structural stability, is widely used in products such as surveillance cameras, access control systems, and consumer smart devices. In the AI-powered security sector, the demand for integrated, precision casings is particularly growing.
