Extrusion Heatsink Process Flow

Extrusion heatsinks are divided into aluminum alloy extrusion heatsink and aluminum copper extrusion heatsink.

Following is the process flow of extrusion heatsink
1.A billet of aluminum is heated to temperatures in excess of 900°F.
2.Next, the billet is pressed and drawn through a die of the desired cross section by a rod with up to 22 tons of force.
3.The extrusion is then manually pulled through the opposite end and cooled.
4.In the final stage, the extrusion is cut to the requested length.
5.At this point secondary processes are then performed. Pioneer Thermal's extrusion molding process is simple and reliable, which greatly shortens the production cycle. Usually our heatsink delivery is within 15 working days after confirm heatsink samples with customer. Our aluminum copper extrusion heatsink transition layer has a fine structure, high heat dissipation efficiency, and can save a lot of high-quality precious non-ferrous metals, effectively reducing costs.
