Should LED heatsink use extruded aluminum or cast aluminum?

​There are two types of heatsinks commonly used in LED manufacturing, namely extruded aluminum heatsinks and cast aluminum heatsinks. In general, the heat sink will be designed according to the corresponding shape and heat dissipation requirements of the LED light.

These two types of heatsinks have their own advantages and disadvantages, which need to be analyzed from different angles, especially in combination with the production method and specific requirements of each business & customer:

  1. If you require a beautiful appearance and complex shape, you should choose a die-cast aluminum heatsink.

  2. If a relatively regular shape and good symmetry is required, an extruded aluminum heatsink can be considered.

  3. With two heat sink products with the same shape, the price of the die cast is usually higher than the extrusion one, but the later processing price of extruded aluminum is higher than that of cast aluminum

  4. In addition, the price of cast aluminum material is relatively cheap, while the cost of extruded aluminum will usually be more expensive.

In fact, the production of LED radiators must be combined with a specific use, it is necessary to comprehensively consider various factors to minimize product costs, including material costs, mold costs, etc. sample...  The choice of production method must be appropriate to the environmental circumstances, ensure safety, and most importantly, have good heat dissipation effect
