Product Overview
High-Density Micro-Channel Copper Cold Plates for AI Server Liquid Cooling
As AI computing density continues to surge, GPU power consumption has surpassed the 700W–1000W range, pushing traditional air-cooling solutions to their physical limits. Liquid cold plates — mounted directly against GPU/ASIC chip surfaces — have become the critical thermal interface in modern AI servers. The micro-channel geometry inside these cold plates directly determines system thermal resistance and heat transfer efficiency.
AXI Metal provides precision CNC machining services for copper cold plates and vapor chamber bases used in AI servers and data center liquid cooling systems. Using high-purity C1100 oxygen-free copper, our high-precision CNC milling process achieves micro-channel structures as narrow as 0.3mm, paired with electroless nickel plating to meet the demanding requirements of high thermal conductivity, corrosion resistance, and solderability.
We support flexible delivery from single-piece prototypes to low-volume OEM validation batches.
Core Manufacturing Capabilities
We produce cnc machined ai server cold plate, GPU liquid cold plate and vapor chamber base for ai server as CNC precision parts.
Micro‑channel CNC Milling
