Hongming Sheng manufactures custom heat sinks, liquid cold plates and CNC thermal management components according to customer drawings and cooling system requirements.

We support aluminum and copper thermal parts, machined cooling structures, fin assemblies and custom components for power electronics, battery systems and industrial equipment.

Custom Liquid Cold Plates

Liquid cold plates can be manufactured with machined channels, embedded tubes or other cooling structures depending on the system design.

• Machined aluminum cold plates
• Copper tube cold plate structures
• Custom inlet and outlet locations
• Mounting holes and threaded features
• Flat interface surfaces
• Sealing and assembly features when required

Heat Sinks & Fin Structures

Heat sink structures can be developed using machined aluminum, extrusion profiles, skived fins or assembled fin structures according to space and thermal requirements.
