Hongming Sheng manufactures custom liquid cooling cold plates for AI servers, GPU, CPU and high-power electronic modules according to customer drawings and thermal interface requirements.

We support copper and aluminum cooling parts, CNC-machined channels, sealing surfaces and custom inlet / outlet structures.

Liquid Cooling Cold Plates

Cold plates transfer heat from GPUs, CPUs and power modules into a liquid cooling loop. Manufacturing accuracy is important at both the cooling channel and component interface.

• GPU and CPU cold plates
• Power module cooling plates
• Custom flow channels
• Inlet and outlet ports
• Mounting and sealing features

Cooling Channels & Sealing Surfaces

• Channel geometry
• Contact surface flatness
• Sealing surface quality
• Mounting hole positions
• Port and connector locations

Copper & Aluminum Cooling Parts

Copper is often selected for high thermal conductivity, while aluminum offers lower weight and good machinability. Material selection depends on the project design.
