What is Die-Cast Heat Sink?

Die casting heat sink is a heat sink component manufactured by die casting. Die casting is a metal casting process characterized by the use of high pressure to inject molten metal (usually aluminum or zinc alloy) into a precision mold cavity, and then the metal is cooled and solidified to form a part of the desired shape. This process can produce metal parts with high dimensional accuracy, good surface finish, complex structure and thin wall.

In heat sink manufacturing, the advantage of die casting is that it can form complex fin arrays, mounting holes, reinforcing ribs and other functional features in one piece, thus achieving a highly integrated design. This not only reduces the steps of post-processing and assembly, and improves production efficiency, but more importantly, the die-cast heat sink has excellent structural strength and consistency, which can effectively manage high heat flux density and ensure stable operation of electronic equipment under various working conditions.

Winshare Thermal Alloy relies on advanced die-casting technology and rich experience to provide you with customized die-casting heat sinks with excellent heat dissipation performance and structural integration.

Detailed explanation of the advantages of die casting materials

The die-casting process can give full play to the characteristics of the selected alloy and provide the heat sink with excellent comprehensive performance.

Aluminum alloy (such as A380, ADC12, A356): Aluminum alloy is the most commonly used material for die-cast heat sinks, and is favored for its excellent thermal conductivity, light weight, good casting performance and cost-effectiveness.

Die-cast aluminum alloy heat sinks can achieve complex and precise fin structures and have good mechanical strength.

Zinc alloy (Zamak series): Zinc alloy has excellent fluidity and can cast extremely complex and thin-walled parts, while having good mechanical strength and corrosion resistance. Although the thermal conductivity is slightly lower than that of aluminum, zinc alloy die-cast heat sinks are an ideal choice in certain applications that require higher structural complexity and precision.

High integration and cost-effectiveness: The die-casting process can form multiple components such as heat sinks, substrates, and mounting bases at one time, reducing subsequent processing and assembly costs. This is especially beneficial for mass production, making die-cast heat sinks a cost-effective and high-performance solution.
