Industrial / Precision Die Casting
Heat Sink
Precision die-cast heat sink providing passive thermal management for electronic components through an extended fin array that maximizes convective heat dissipation. The aluminum alloy construction combines low weight with high thermal conductivity for effective cooling in space-constrained designs. Widely used in power modules, industrial control boards, and embedded computing platforms.

Frequently Asked Questions
What fin geometries are available for this die-cast heat sink?
CZT offers straight fin, cross-cut fin, and pin fin configurations depending on airflow direction and space constraints. Straight fins suit unidirectional airflow; pin fins perform better in omnidirectional or low-airflow environments. Custom fin geometry can be incorporated into the die tooling for OEM orders.
How is the mounting base surface prepared for thermal interface materials?
The mounting base is machined after casting to achieve the flatness and surface roughness required for effective thermal interface material contact. This minimizes air gaps between the heat sink and component package, directly reducing thermal resistance at the critical junction-to-heat-sink interface.
What is the minimum order quantity for custom heat sink tooling?
MOQ for custom die-cast heat sink tooling varies based on part complexity and die size. CZT typically works with OEM customers to amortize tooling costs over production volumes. Contact CZT's sales team with your thermal specifications and target volume for a tooling and unit price quotation.
