Product Description
A Cold forged heatsink is a good alternative to casting to form complex shapes with excellent thermal conductivity.
The Cold forging process can make fins almost perfectly straight, allowing for more fins per square mm. Cold forged heatsink shapes include plate fin heat sinks, round pin heat sinks, and elliptical fin heat sinks. Cold forged heatsink manufacture lends itself very well to using aluminum and copper because high temperatures are not required to shape these metal heatsinks, and they can be formed with minimal damage.
Secondary machining operations such as holes, chamfers, and steps can usually be included in the cold forged heatsink manufacture, reducing waste.
Product Features
Integrated Cold Forged Monolithic Structure
One-step cold forging molding for base + pin fins as a single aluminum piece, zero thermal interface gap between fins and base, far lower thermal resistance than assembled split heat sinks.
01
Ultra-Dense Vertical Pin Fin Design
Straight, uniform cylindrical pin fins arranged closely; more pins per unit area to maximize air contact surface, outstanding passive convection & radiation cooling efficiency.
02
Flat Smooth Mounting Base
Precision flat circular top plate for tight attachment with heat sources; customizable tapping holes, counterbores and chamfers via secondary CNC machining.
03
Uniform Black Anodized Surface Treatment
Matte black oxidation coating enhances infrared heat radiation, anti-oxidation, scratch-proof and long service life for outdoor lighting equipment.
04
Lightweight Solid Aluminum Body
Made of high-purity aluminum alloy with superior thermal conductivity, lighter weight than copper cold forged radiators, easier product assembly.

Advantages
Over Cast/Extruded Heat Sinks
Superior Thermal Conductivity
Cold forging forms metal without high-temperature melting, retaining original high thermal conductivity of aluminum; no internal air pores common in cast heat sinks.
Higher Fin Density & Larger Cooling Area
Cold forging produces perfectly straight thin pins, enabling far more fins per square millimeter than extrusion casting, drastically improving heat dissipation capacity.
Minimal Material Waste & Cost Saving
Integrated forming + one-stop secondary machining (tapping, countersink, chamfer) reduces extra processing steps and raw material loss, lowering overall manufacturing cost.
No Structural Damage During Molding
Cold forming at room temperature avoids metal grain damage from high-temperature casting; finished product features higher structural strength and vibration resistance.
Flexible Custom Geometry Support
Craft adaptable for round pin, plate fin, elliptical fin shapes; we tailor pin height, density, base thickness and mounting hole layout to match clients' thermal power demand.
Uniform Heat Dissipation Without Hotspots
360° surrounding pin layout achieves omnidirectional air flow circulation, evenly disperses heat and eliminates local overheating of high-power chips.
