The die-casting process Unparalleled cost efficiency with high quantities
The die-cast process allows the production of heat sinks with complex geometries at low costs per piece. From tiny components for PCB cooling weighing only a few grams to custom designed electronic cooling housings and heavy cooling plates with a weight of several kilograms for liquid cooling, virtually any application-specific form and size can be implemented. Typical die-cast materials are aluminum, zinc and magnesium, although aluminum is by far best suited for the manufacture of heat sinks.
How it works
The metal is placed in a steel form, the die-casting tool, under high pressure and at high speed. This tool precisely defines the shape of the cooling element and can be provided with several cavities depending on the size of the particular heat sink. This process enables the production of multiple heat sinks in one operation.
The benefits
- Very low costs per piece for series production despite tool costs
- Aluminum die-cast parts are lightweight and withstand very high operating temperatures
- Improved thermal dissipation of sturdy, rigid and corrosion-resistant aluminum heat sinks
- CNC machining necessary only on areas with very high surface quality requirements
