The material that produces aluminum heatsink heat conduction property is good, at present the majority uses 6063 aluminium alloy, its have the characteristic such as easy processing, heat dissipation performance is good, mechanical property is good. Additional need from ingot, mold, extrude craft a few respects to cooperate, ability produces heat sink profile smoothly.

Because the mold of aluminum extrusion heat sink profiles are a lot of long and thin fin, want to bear very big extrusion pressure, every heat sink fins should have very high strength and toughness, if the performance between each other has very big difference, easy to make the strength or toughness of those teeth produced fracture.

Can smooth extrusion success, the key is the design of the mold to reasonable, manufacturing to accurate, this aluminum heat sink manufacturers of higher technical requirements, only strong manufacturers can complete from mold design extrusion to the finished product of the whole process.
