II. Product Features
(I) Core Performance Advantages
1. High-precision adaptation: mold accuracy is controlled at ±0.05mm, strictly following the EIA-310-D rack standard, frame installation hole position, guide rail spacing error ≤0.1mm, achieve seamless mounting of network equipment, support automated cabinet integration.
2. High-strength load-bearing: using 345MPa tensile strength cold-rolled steel plate, hardened by stamping cold work, frame static load-bearing capacity of 80-150kg, can stably support 4-8 standard server modules, ensure long-term operation without deformation.
3. Efficient heat dissipation design: the honeycomb heat dissipation holes on the side panels are optimized by fluid simulation, with an opening rate of 40%-60%. With the cabinet airflow organization, the heat dissipation efficiency is increased by 25%, effectively reducing the risk of equipment thermal failure.

III. Product Details
(I) Process Flow
1. Mold Development: Based on the 19-inch rack standard, a multi-station progressive die is designed, integrating blanking, bending, and tapping functions. After CNC processing and laser quenching, the mold life exceeds 800,000 times, ensuring the consistency of batch parts.
2. Raw material processing: SPCC cold-rolled steel plate (thickness 1.5-2.5mm) is selected, and pre-treated with degreasing, phosphating, and passivation to enhance the adhesion of the spray coating and adapt to the constant temperature environment of the data center.
3. Stamping: On the 800-1250T servo punch press, continuous die stamping is used to form the frame frame and heat dissipation side panel in one time, and the M5 installation screw hole tapping and guide rail bracket riveting are completed simultaneously, with a dimensional accuracy of ±0.05mm.
4. Surface treatment: electrostatic spraying process (coating thickness 70-90μm), optional RAL9005 (cabinet black) color, salt spray test ≥1000 hours, to resist the humid and static environment of the computer room.
(II) Typical application scenarios
 Data center cabinet: as the main body of the 2U/4U rack-mounted frame, it carries servers and switch modules, and with the hot and cold channel design, it supports the deployment of large data center clusters such as Tencent Cloud and Huawei Cloud. A single cabinet can integrate 16-32 standard modules.
 Enterprise computer room upgrade: replace the traditional sheet metal frame, accurately adapt to Dell PowerEdge, Huawei FusionServer and other servers, and quickly upgrade the computing power density of the computer room through modular stamping parts (power compartment, cable management trough) to meet the expansion needs of 5G services.
 Edge computing site: provide a protective frame for outdoor integrated cabinets. The high strength and corrosion resistance of stamping parts ensure the stable operation of edge servers in high temperature and high humidity environments, such as smart parks and industrial Internet of Things edge nodes.
(III) Quality control system
Implement "full-process quality inspection": full-size three-coordinate inspection of the first piece, process sampling of every 300 pieces to monitor hole tolerance and coating adhesion, 100% of the finished products pass the load-bearing test (loaded with 150kg for 72 hours) and vibration test (simulating cabinet transportation vibration), and key parts comply with the GB/T 15395-2023 metal cabinet standard, laying a solid "metal foundation" for data center rack deployment.
