What is Die Casting Cold Plate?

We melt aluminum, zinc, or magnesium. We inject it fast into a mold under high pressure. It cools into one solid plate with complex inner channels and outer mounts. No extra parts.
Core Process:
High-pressure injection: Metal fills mold in seconds. One-piece build.

Winshare die cast cold plate is different from other cold plate processes

When choosing the best cold plate solution for your application, it's crucial to understand the advantages and disadvantages of different manufacturing processes. The table below compares the key characteristics of die casting cold plates with other mainstream cold plate processes.
Process type Manufacturing method Runner complexity Thermal performance Structural integrity Cost vs. Volume Integration
Die Casting Cold Plate High-pressure molten metal is formed in one go High (complex 3D runners Medium-high (balance performance and cost) Very high (one-piece molding without welds) Low Cost/Unit (High Volume) Extremely high (can be integrated with multi-function)
Deep Hole Drilling Cold Plate Precision drilling of solid metal blocks Extremely high (custom 3D path) Extremely High (Extreme Performance) Highest (pure integration) High Cost/Unit (Low Volume) Low (mainly runner)
Brazed/Bonded Fin Cold Plate Fins brazed/bonded to the base plate and then sealed High (high surface area fins) High (excellent heat transfer efficiency) High (brazing is better) Medium Cost/Unit (Medium to High Volume) Medium (simple functions can be integrated)
FSW Plate (Friction Stir Welding Cold Plate) CNC machined by runners following of friction stir welding High (complex 2D/3D) High (stable thermal contact) Very High (solid-state weld is excellent pressure resistance) Medium (Medium to High Volume) High (suitable for large scale structural integrated)
Extruded Cold Plate Metal profiles are extruded and formed Low (simple straight passage) Medium-low (basic cooling) High (Integrated Profile) Very low cost/unit (very high volume) Low (basic profile)

Winshare Surface Treatment & Finishing: Enhancing Customization and Batch Quality

Die-cast cold plates typically have a good surface finish, but further surface treatment and finishing can significantly improve their corrosion resistance, wear resistance, insulation, or aesthetics in specific application scenarios. Winshare offers a variety of professional surface treatment solutions to meet your customization needs and ensure consistency and high quality of bulk products.
Anodizing
Forms a dense oxide film on the surface of aluminum alloys, significantly improving corrosion resistance, hardness, and insulation, and can be colored to enhance aesthetics, meeting customized appearance needs.
 
Electroless Nickel Plating
A layer of nickel-phosphorus alloy is uniformly deposited on the metal surface, providing excellent corrosion resistance and wear resistance, suitable for fluid environments with high corrosion protection requirements, ensuring the long-term reliability of batch products.
 
Passivation
Chemical treatment of stainless steel or certain aluminum alloys to remove surface impurities and form a passivation film that enhances its inherent corrosion resistance, suitable for batch applications in specific environments.
 
Sandblasting/Painting
Used to improve surface roughness or provide additional protective layers and colors, suitable for applications with special requirements for appearance, and for the individualization of bulk products.
 
In addition to surface treatment, we also offer high-precision CNC finishing services to ensure the flatness of the contact surfaces between cold plates and heat sources, as well as the accuracy of critical dimensions such as interfaces and mounting holes, ensuring optimal thermal contact and system integration, and providing superior precision assurance for your bulk products.

Winshare Die Casting Cold Plate Customization & Mass Production Process

Customized needs assessment and conceptual design
 
Gain insight into your heat load, size, fluids, costs, and volume production needs to develop a preliminary product concept and custom design direction together.
