26. What Steps Should I Take So That I’ll Be Able To Extrude Aluminum Heat Sinks?

Here is how you extrude aluminum heat sinks:
Step 1: Prepare the Materials You Need

  • Initially, start up with creating and designing how you want your aluminum heat sink to look like.
  • Immediately afterwards, begin the preparation for the die so you’ll be able to finish things faster.
  • Then heat the die to 450-500°C.
  • While the die is being heated, make sure to keep producing aluminum. So that the metal keeps moving and the heat is continued.
  • It’s important to take note that you should be pre-heating the aluminum billet while you’re doing so and then you insert the die inside the aluminum press.
  • Heat the aluminum billet to 450-500°C to shape it.
  • Apply a releasing agent to the malleable aluminum billet. Then you put it in the heat press.

Step 2: The Official Extrusion Process

  • At this point, a 15,000-ton hydraulic press will begin extrusion. Once pushed against the extrusion die, the extrusion will make sure that it takes on the shape of the die you prepared. How you shape the die is what determines the final shape to be.
  • Once finished, the product will then be squished and then quickly withdrawn. Cool it in a water bath or using table fans.
  • Then cut the extrusion to the table’s length and cool it to room temperature.
  • Align the extrusion after stretching it. Extrusion forms will be extended.

Step 3: The Secondary Machining Process

  • Even though you’ll have a final product, it’ll need to be further machined. The aluminum heat sink will now be modified via the use of secondary machining.
  • Additional options for the aluminum heat sink include: applying a surface finish,punching holes and creating pockets in it.
  • Finally, you will put the aluminum heat sink through its paces before packing and shipping it.
