II. Product Features
(I) Core Advantages
1. Lightweight and high strength: The density of aluminum alloy profiles is only 1/3 of that of steel. After stamping and strengthening, the tensile strength can reach 200-300MPa. While reducing the overall weight of the equipment (weight reduction of 30%-50%), it ensures the structural bearing capacity and is suitable for electronic equipment, new energy vehicles and other scenes with strict requirements for lightweight.
2. Precision adaptability: The mold processing accuracy is controlled at ±0.05mm, the dimensional tolerance of the stamping parts is extremely small, the hole position and bending angle are accurate, and it can be seamlessly matched with other parts to meet the high-precision assembly requirements of automation equipment, such as robot joint connectors, to ensure the operation accuracy of the equipment.
3. Weather resistance and corrosion resistance: The surface of the aluminum alloy naturally forms an oxide film. After stamping, it is combined with anodizing, spraying and other processes. The salt spray test is more than 1000 hours. It can be stably used in harsh industrial environments such as humidity, acid and alkali, and extend the service life of the equipment.

　　(I) Process Flow

　　1. Profile pretreatment: Select industrial aluminum alloy profiles such as 6061 and 6063, cut them into suitable lengths, and then remove burrs and oil to ensure the flatness and cleanliness of the stamping surface.

　　2. Mold design: According to the product structure requirements, use CAD/CAM technology to design special molds, including punching molds and bending molds, which are processed by CNC and heat treated (mold hardness HRC55-60) to ensure accuracy and service life.

　　3. Stamping: On a 100-500T precision punching machine, complete the punching, bending, stretching and other processes, and use a servo control system to accurately control the pressure and stroke to achieve one-time molding of complex shapes, such as arc bending of electronic equipment housings and stamping of heat dissipation hole arrays.

　　4. Surface treatment: Optional processes such as anodizing (forming a colored oxide film to enhance corrosion resistance and beauty), spraying (customized color to enhance protection), and electrophoresis (high corrosion resistance, suitable for harsh environments) can meet the appearance and performance requirements of different industries.

　　(II) Applicable scenarios

　　 Electronic equipment: Processing mobile phone middle frames and laptop cooling brackets, using the lightweight and easy heat dissipation characteristics of aluminum alloy, combined with the precision structure of stamping, to ensure the thinness and stability of equipment, such as high-end model components of consumer electronics brands.

　　 Automated equipment: Manufacturing robot arm connectors and equipment frame rails, relying on high-precision stamping holes and high-strength structures, to achieve modular assembly and precise operation of equipment, and adapt to industrial robots and intelligent storage equipment.
