II. Product Features
(I) Core Performance Advantages
1. High-strength structure: using cold-rolled steel plates with tensile strength ≥345MPa, hardened by stamping and cold working, the frame load capacity is increased by 25%, which can stably support 800-1200kg equipment load and ensure that the cabinet will not deform for a long time.
2. Precise adaptability: the mold accuracy is controlled at ±0.05mm, the stamping part size is 1:1 matched with the 19-inch cabinet standard, and the installation hole position error is ≤0.1mm, realizing seamless integration of network equipment and supporting automated cabinet assembly.
3. Efficient heat dissipation design: honeycomb heat dissipation holes are optimized by fluid mechanics simulation, with an opening rate of 45%-55%. Compared with traditional punching, the heat dissipation efficiency is increased by 30%, effectively reducing the risk of equipment failure caused by high temperature.

III. Product Details
(I) Process Flow
1. Mold Development: Based on the ANSI/EIA-310-D cabinet standard, a multi-station progressive die is designed, integrating blanking, punching, and bending functions. After CNC milling and EDM finishing, the mold life exceeds 1 million times, ensuring the consistency of batch parts.
2. Raw material processing: SPCC cold-rolled steel plate (thickness 1.2-2.0mm) is selected, and pre-treated with degreasing, phosphating, and passivation to enhance the adhesion of the surface coating and lay the foundation for the spraying process.
3. Stamping: On a 630-1000T servo punch press, a continuous die is used to stamp the cabinet frame and heat dissipation side panel in one step, and the M6 installation screw hole tapping and guide rail bracket riveting are completed simultaneously, with a molding accuracy of ±0.05mm.
4. Surface treatment: electrostatic spraying process (coating thickness 60-80μm), optional RAL7035 (cabinet gray) and other colors, salt spray test ≥960 hours, suitable for the constant temperature and humidity environment of the data center all year round.
(II) Typical application scenarios
 Data center cabinet: as the main frame of the cabinet and the rear door heat sink, the honeycomb holes cooperate with the air conditioning system to achieve cold and hot channel isolation, ensuring the stable operation of 300+ server clusters, such as Tencent Cloud and Alibaba Cloud computer room projects.
 Enterprise computer room renovation: replace old cabinet accessories, accurately adapt to Dell and Huawei server installation, and quickly upgrade cabinet functions through modular stamping parts (power compartment bracket, cable management trough) to meet the expansion needs of network equipment in the 5G era.
 Edge computing node: provide protective side panels and reinforcement frames for outdoor integrated cabinets. The high strength and corrosion resistance of stamping parts ensure that edge servers can operate 7×24 hours in high temperature and high humidity environments, such as smart transportation and industrial Internet of Things scenarios.
(III) Quality control system
The “three inspections + one test” standard is implemented: the first piece is scanned in full size by a three-coordinate measuring machine, and every 200 pieces are sampled during the process to monitor the hole tolerance and coating thickness. 100% of the finished products pass the load-bearing test (loaded 1200kg for 48 hours) and heat dissipation simulation test. The key parts comply with the GB/T 3047.2-2023 cabinet standard, building a solid “metal defense line” for the data center infrastructure.
