Die-Cast Heat Sinks

Die-cast heat sinks are manufactured by injecting molten metal (e.g., aluminum or zinc) into reusable steel molds, creating intricate, near-net-shape cooling components. This process excels for high-volume applications requiring complex geometries, such as integrated mounting bosses, cavities, or EMI shielding enclosures.

Our proprietary Technology optimizes mold cooling channels and gate placement, achieving 15% faster cycle times and 10% lower porosity than industry standards. Prototype tooling ready in 10-14 days, mass production in 3-4 weeks.

Why Choose Die-Casting?

✔️Cost-Effective Complexity – Combine heat sinks with enclosures, brackets, or connectors in a single part.

✔️Rapid High-Volume Production – Cycle times as low as 30 seconds per part.

✔️Material Versatility – Aluminum for lightweight cooling, zinc for EMI/RFI shielding.

✔️Durability – Seamless designs resist vibration and thermal cycling fatigue.
