Custom Aluminum Extrusion Service

We make customized aluminum heat sinks from Aluminum extrusion technology and it works this way: firstly the aluminum ingot will be heated at high temperature to about 520~540℃,and its liquid will flow through the extrusion die with grooves under high pressure to make the preliminary heat sink, and finally the preliminary heat sinks will be cut to its length.
Except aluminum extrusion, on major cases, the heat sinks need to be CNC machined as post processing, including holes drilling and tapping. But if you don’t need to cut any complex shapes with an extrusion tool in small quantities, we can directly produce from milling or wire cutting, which is a good solution for small orders.
