Die Casted Liquid Cold Plate

Die Cast Cold Plates are suitable for complex liquid cooling. Die casting is an efficient, economical process offering a broader range of designs than any other manufacturing technique. Die castings are monolithic. They combine many functions in one, complex shaped part. Produced at high rates of production with little or no machining required.

The process involves forcing molten metals into a die cavity to create reproducible three-dimensional parts. It can quickly yield complex, precise, rigid cast parts with smooth surfaces that don’t need intense secondary machining.

Many customers will start their designs with a machined aluminum liquid cold plate for prototyping, pre-production and small volume production. As their production volume grows, the tooling investment cost to transition to a die casted part, provides for a good return, due to the lower cost of the cold plate.

Benefits Include:

• Can be produced with thinner walls.
• Have the feel and appearance of quality.
• Complex shapes within closer tolerances.
• Holes can be cored, and made to tap drill sizes.
• External threads on parts can be readily die cast.
• Provide parts which are durable, dimensionally stable.
• Corrosion resistance of die casting alloys rates from good to high.
• Can be produced with surfaces simulating a wide variety of textures.
• Inserts of other metals and some non-metals can be die cast in place.
• Can be easily plated or finished with a minimum of surface preparation.
• Much stronger than plastic injection moldings with the same dimensions.

Because die castings do not consist of separate parts, welded or fastened together, the strength is that of the material, not that of threads or welds. Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant. Die casting also provides integral fastening elements, such as bosses and studs, which can result in assembly economies. They can produce thousands of identical castings within specified tolerances before additional tooling may be required.
