Hydraulic Press Machine Was Widely Used in AI ServerUpdate：2025-05-15 Hits：12
Hydraulic press machine usually using external force to cause metal or non-metal materials to undergo plastic deformation to form parts of a specific shape. In AI servers, the following scenarios may be widely used with hydraulic press.1. Manufacturing of heat dissipation components
Heat sink/heat pipe:
Through forging process, aluminum or copper materials are processed into dense fin-shaped heat sinks, or heat pipes (liquid working fluids are vacuum-encapsulated inside) are formed to improve heat conduction efficiency.
Advantages: Forging process can realize ultra-thin and high-density fin design of heat sink (such as fin thickness < 0.5mm), increasing the heat dissipation area.
Liquid cooling components:
The cold plate in the liquid cooling system needs to be manufactured through forging or stamping process to ensure the flow channel of the coolant to ensure uniform flow and take away the heat of the chip.
Case: Some AI servers use immersion liquid cooling. The cold plate needs to fit the GPU chip precisely. The forging process can ensure the flatness of the contact surface (tolerance ±0.01mm).
2. Lightweight design of structural parts
Chassis frame:
Use high-strength aluminum alloy or titanium alloy to manufacture an integrated chassis frame through forging process, while ensuring strength and reducing weight (such as 30% weight reduction compared with traditional sheet metal process).
Application scenario: Edge computing AI servers need to take into account both portability and shock resistance, and forged magnesium alloy frames can meet these requirements.
Motherboard bracket/interface module:
Forging PCIe slot brackets, power interfaces and other components to improve mechanical strength and avoid poor contact caused by vibration.
3. Electromagnetic shielding and signal optimization
Shielding cover:
The internal chips of the server (such as CPU, GPU) need electromagnetic shielding to reduce interference, and the forged metal shielding cover can achieve seamless fitting through precision stamping.
Technical points: The edge of the shielding cover needs to be folded through the forging process to ensure good grounding with the motherboard, and the shielding efficiency can reach more than 60dB.
Antenna module:
In the wireless communication module of the AI server (such as 5G/6G network card), the forged metal antenna bracket can optimize the signal radiation direction.
The hydraulic press machine mainly serves the needs of heat dissipation, structural strength and lightweight in AI servers, and is one of the key manufacturing technologies to improve server performance and reliability. With the explosion of AI computing power demand, the forging process will be deeply integrated with new materials and intelligent manufacturing in the future, driving server hardware to develop in the direction of higher efficiency and lower energy consumption.
