Product details

DONGRUN CASTING is one of the leading heat sinks manufacturers and suppliers in China. We have customized heat sinks made in China, welcome to check the quotation with our factory.

Product Introduction
Aluminum radiator profiles are mainly three typesg: flat wide shape, or a fishbone-shaped comb-shaped; round or oval-shaped;and branching shape. Compared with the other aluminum extruded sections radiator has its own characteristics: the distance between the heat sink is short, between two adjacent heat sink to form a trough, and its large aspect ratio; differential wall thickness, heat sink teeth thin, and its roots in the bottom thick. The mold design, manufacturing and production are very difficulty for the complexity of the shape of radiator extruded sections.
