Our Dongguan precision machining factory specializes in manufacturing AI liquid cooling components. We offer one-stop custom fabrication services for AI liquid cold plates, covering aluminum alloy and oxygen-free copper micro-channel cold plates. Our full workflow includes drawing evaluation, 5-axis CNC precision milling, friction stir welding / vacuum brazing, surface treatment and helium leak detection.

The internal micro-channel structure, flatness of sealing surface and inner channel roughness of liquid cold plates directly determine heat transfer efficiency and long-term leak reliability. Equipped with high-speed CNC machining centers, we tightly control tolerance within ±0.005mm for precision machining of complex micro-channels. Friction stir welding solid-state sealing eliminates weld pores and cracks to reduce liquid leakage risk at source. All finished products pass hydraulic pressure and helium mass spectrometer dual leak testing to guarantee 7×24h stable operation of AI servers.

Our products are suitable for high-density AI servers, GPU accelerator cards and supercomputing clusters. Customization is available according to customers’ thermal simulation solutions, supporting prototype sampling and mass production.

With years of experience in precision machining, we continuously supply highly reliable cooling components for AI computing, new energy, medical and aerospace clients, helping global computing infrastructure reduce costs and improve efficiency.
