II. Product Features
(I) Core performance advantages
1. High-precision modular adaptation: The mold accuracy is controlled at ±0.05mm, strictly matching the internal component size of the industrial computer (such as ATX motherboard, PCIe expansion slot), the installation hole tolerance is ≤0.1mm, supporting automated production line assembly, realizing the "plug and play" of the motherboard and module, and ensuring the operation accuracy of the equipment.
2. High-strength impact resistance: Using cold-rolled steel plate (or 6061 aluminum alloy) with a tensile strength of 345MPa, after stamping and cold working hardening, the frame's deformation resistance is increased by 30%, and it can withstand 10G vibration and 50J impact, and is adapted to the high-frequency vibration environment of industrial field robotic arms and production line equipment.
3. Efficient heat dissipation design: The back panel honeycomb heat dissipation holes + side fence-type vents, the opening rate is 45% - 60%, and the "air duct circulation" is formed with the industrial computer fan, and the heat dissipation efficiency is increased by 25%, effectively reducing the risk of failure of the CPU and power module due to high temperature.

III. Product Details
(I) Process Flow
1. Customized mold: Based on the size standards of industrial computers (such as 1U/2U rack-mounted and desktop-mounted), 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 to ensure the consistency of batch parts.
2. Raw material selection: SPCC cold-rolled steel plate (thickness 1.2-2.0mm, suitable for heavy-duty industrial computers) or 6061 aluminum alloy (thickness 1.5-3.0mm, suitable for lightweight industrial computers) is selected, and the surface coating adhesion is enhanced after degreasing and phosphating pretreatment.
3. Stamping: On a 630-1000T servo punch press, continuous die stamping is used to form the frame frame and heat dissipation backplane in one step, and M3-M6 installation screw hole tapping and guide rail bracket riveting are completed simultaneously. The forming accuracy is ±0.05mm to ensure the precise installation of internal components.
4. Surface treatment: electrostatic spraying (coating thickness 60-80μm, optional industrial control gray and black) or anodizing (aluminum alloy parts), salt spray test ≥960 hours, to resist the erosion of oil, dust and humid environment in industrial sites.
(II) Typical application scenarios
Industrial automation production line: As a 1U rack-mounted industrial computer frame, it carries motion control cards and PLC modules. The high-strength structure can withstand the high-frequency vibration of the production line robot, and the efficient heat dissipation ensures that the visual inspection system can run 7×24 hours, such as automobile welding lines and 3C product assembly lines.
 IoT edge computing: Processing desktop industrial computer frames, adapting to Intel NUC motherboards and Mini-ITX modules, lightweight aluminum alloy materials meet the "small size and high reliability" requirements of edge nodes such as smart warehousing and environmental monitoring, and integrating 4G/5G communication modules to achieve real-time data upload.
 Intelligent equipment control: Customizing 2U industrial computer frames for CNC equipment and laser cutting machines, modular positions adapting to motion control cards and IO expansion modules, precise hole positions to ensure equipment linkage control accuracy, and help intelligent equipment processing errors ≤ 0.01mm.
(III) Quality control system
Implement "full-process digital quality inspection": During the stamping process, the pressure sensor monitors the mold load in real time and warns of deformation risks; the first piece is scanned in full size by a three-coordinate measuring instrument to generate a deviation report; during batch production, 1 piece is selected for every 50 pieces for vibration testing (simulating 10G vibration on industrial sites) and salt spray testing, and 100% of key dimensions pass the pass and stop gauge to ensure that the product complies with the GB/T 15395-2023 metal cabinet standard and the IPC-A-610 electronic assembly standard, building a solid "metal defense line" for the stable operation of industrial control equipment.
