LED lighting heat sinks or enclosure produced by aluminum die casting process , it will be drilled and tapped, or CNC machining, as well as painting if necessary.

if the volume is small and the design is available for gravity casting or sand casting, we can change the process to save tooling cost.

1.Advantages of die casting process

1.1 high volume but low cost Compared with aluminum sand casting and gravity casting, aluminum die casting can produce precision parts in high volume at low costs.

1.2 good surface finish and good dimensional accuracy,Aluminum die casting generally has good surface finish and good dimensional accuracy. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size.

2,Economize the product’s cost, improve product\'s service life

 2.1,When the production volume is  large, the cost is lower than lathe processing heat sink, what’s more, the common section aluminum heat sink are split-type, so it have to involve in artificial assembly costs.

2.2,We made a comparison in the common lathe processing section aluminum heat sinks, die casting heat sinks and cold forging unibody type heat sinks:
　　①,In the addition of the same size and shape, the cold forging unibody type heat sinks can be applied on bigger power appliance than the other heat sinks. For example, the common lathe processing section aluminum lamp cups can be only used for cooling the 3W bulb, but our heat sinks can be used for cooling 5W bulb. If the common heat sinks applied on the cooling of 5W bulb, the material and size must be added, the cost will higher than the cold forging unibody type heat sinks much more.
　　②,The more worthy of praise, if you put our products and common heat sinks on the same power bulb respectively, you can find that own to the excellent radiation capacity, the temperature of the bulb which used our heat sinks is sharply lower than the others,which expanded the service life of the appliance obviously.
