Custom Precision CNC Machined Liquid Cooling Manifold

The liquid cooling manifold is a critical fluid distribution and collection component used in advanced thermal management systems. It is widely applied in EV battery packs, electric drivetrains, and power electronics cooling systems. Its primary function is to precisely distribute and collect coolant flow, ensuring uniform temperature control and stable thermal performance across multiple cooling channels.

As power density continues to increase in electric vehicles and energy storage systems, thermal management architectures are becoming more complex. As a key interconnection element between cold plates, piping networks, and heat exchange modules, the cooling manifold must deliver precise flow distribution, low pressure drop, and reliable sealing performance within a compact design space. Its structural design and machining accuracy directly impact the overall efficiency and stability of the thermal system.
 

Engineering & Design Capabilities
We provide end-to-end engineering support from concept development to production release, including fluid structure design optimization and simulation analysis. During the development stage, CFD-based flow and thermal simulations are applied to optimize internal channel design, reduce pressure losses, and improve flow distribution uniformity and overall cooling efficiency.

Based on different application scenarios—such as battery pack thermal systems, electric motor controllers, and power electronics cooling modules—we offer fully customized designs to meet specific space constraints, interface requirements, and flow performance targets.
 

Manufacturing Capabilities
The liquid cooling manifold is manufactured using high-precision CNC machining processes, enabling the production of complex internal flow channels and tight-tolerance geometries.

With advanced multi-axis machining capabilities, we are able to machine intricate internal structures, deep cavities, and integrated interfaces in a single setup, significantly reducing assembly errors and improving overall system reliability.

Through precise fixturing and strict process control, we ensure dimensional consistency and repeatability across both prototype and mass production batches.
 

Materials & Surface Finishing
Depending on application requirements, we offer a variety of material options, including aluminum alloys (such as 6061 and 6082) and other high-performance metals to achieve an optimal balance between lightweight design and corrosion resistance.

Surface treatment options include anodizing, hard anodizing, protective coatings, and corrosion-resistant finishes, which enhance durability and long-term stability when operating in coolant environments.
 

Quality Control
All products undergo strict quality inspection prior to delivery, including CMM dimensional inspection, sealing/leak testing, and verification of critical flow channel consistency, ensuring full compliance with design specifications.

Our production process follows a fully traceable quality management system, covering raw material inspection, in-process control, and final inspection to guarantee reliability and consistency in real-world operating conditions.
