The powerbox consists of integrated CNC Milling of AL6061-T6 aluminum alloy, with rectangular structure. The outer surface has been subjected to 120# sand treatment and silver anodizing and presents a uniform matte texture, the aesthetics, Wear resistance and corrosion resistance combined. The inner cavity is flat without reinforcements, and the side walls are equipped with projections and positioning columns with cast holes. The outputs of the cables and the passages as well as the spaces for attaching the module are reserved on specific sides, which makes different requirements such as electrical insulation, Heat dissipation and compatibility of the assembly can effectively meet.
Phase 1: After the raw material edges have been cut precisely, key structures such as shells, Interfaces and mounting holes formed by high-precision CNC milling with strict tolerance control to ensure the precision of the assembly.
Step 2: After machining and forming, the product enters the process of surface treatment. First, the sand process 120# is used to spray aluminum abrasive at high speed to the surface of the workpiece by compressed air, which effectively eliminates remaining tool marks during CNC milling. At the same time, a uniform, delicate and controllable matte texture forms on the metal surface, providing an ideal substrate for subsequent anodizing.
Step 3: An anodized treatment in glossy silver is then carried out, to form a dense aluminum oxide film on the product surface by electrochemical reactions. This film not only gets a uniform, vivid silver color, but also greatly improves the wear and corrosion resistance and effectively blocks the external environmental erosion of the inner structure, thereby extending its service life.
Dongguan Shengpeng Precision Technology Co., Ltd. has a mature customized production capacity and can customize the dimensions, wall thickness, adjust the material and the process of surface treatment of the power boxes flexibly according to the customer's needs and provide comprehensive precision milling services. With standardized quality control and an experienced technical team, we guarantee every precise and controllable phase, from the raw materials to the end products, by supplying individual components of high quality and highly customized.
