Product Details Key Industries Related Products
High Pressure Die Cast Heat Sinks are a cost-effective option for high volume applications that are weight-sensitive and require superior cosmetic surface quality or complex geometries otherwise not achievable in alternative heat sink manufacturing methodologies. Die Cast Heat Sinks are produced in near net shape, require little to no additional assembly or machining, and can range in complexity. Die cast heat sinks are popular in LED and 5G markets due to their unique shape and weight requirements as well as high volume production needs.
High Pressure Die Casting enables us to produce complex shapes with a high degree of accuracy and repeatability. Our experienced design and manufacturing team can help you custom design a die cast heat sink optimized for your application to maximize heat transfer and cost efficiency while minimizing weight, assuring you optimize your investment in die cast tooling.

Die Cast Heat Sink Solutions
- Complex heat sink geometries with little to no secondary machining operations required
- Ideal for high volumes of complex geometries
- Modified Die Cast Heat sinks can include additional thermal technologies such as embedded heat pipes, copper heat spreaders, or vapor chambers for additional thermal performance
- Die casting can be used for heat sink bases only so you can combine with other fin types like folded or zipper fin stacks.
