Round Pin Fin Diameter 110mm Al1070 Anodizng clear Cold Forged Heat Sink For Led Light

Quick Detail

Description

    This cold forged heat sink is based aluminum 1070 material to processing, first of all, we check the raw material dimension is fine or not, the second is that according to the drawing, use Hydraulic press machine to do the roughcast, the third is that accroding to the drawing, use the wood machine to cut the  outline dimension, the forth is that use the CNC to do exact dimension, the fifth is do anodizing clear, the last step is riveting, and then inspection/packing. First inspection and patrol inspection are done in processing. 

Note

Cold forging is a highly precise manufacturing process in which the workpiece is formed under high pressure and low temperature. The process ensures that no air bubbles, porosity or other impurities are trapped in the material, and thus produces products with exceptionally high quality.

In making aluminum heat sinks, cold forging can produce pins that are 50 times as tall as their diameters – an aspect ratio that is considered impossible with other methods, such as die-casting or extrusion.

Unlike stamped-fin or bonded-fin heat sinks, the pins on a forged heat sink are an integral part of its base plate – they are simply squeezed out of the base. There is no air gap or thermal interface between the pins and the base. Heat can dissipates easily from the base to the pins without additional resistance.
