  The aluminum extruded heat sink has the characteristics of beautiful appearance, light weight, good thermal performance and great energy saving effect. The surface of the extruded aluminum heat sink is anodized for surface treatment to increase the corrosion resistance, wear resistance and appearance of the aluminum profile. Aluminum extrusion heat sink are generally used for electronic components and cooling systems. Sinda Thermal can provide reliable cooling solutions in natural convection environments based on the existing mature aluminum extrusion heat sink technology. The aluminum extrusion section is formed by pushing the aluminum billet through the tooling die, and the complex fin structure can be accomplished by the extrusion tooling die, These complex fins can increase the heat dissipation surface area and reduce the cost and time of aluminum ingot extruding.

Why select the aluminum extrusion heat sink?

1) The production is more efficient than stamped heat sinks; 

(2) More cost-effective than machining; 

(3) A variety of standard shapes and sizes are available; 

(4) Easy customization, lighter than copper, excellent thermal performance;

(5) The MAX CLIP fastener system does not require installation hardware and tools.

Aluminum extruded heat sink: how they are proceeding?

  In the aluminum extrusion process, the metal is heated to a point that is soft enough that it can be extruded through an extrusion die, but cannot be manipulated when it's totally molten because it will drip. A hydraulic press pushes a plunger into the billet, forcing the aluminum through a tightly designed extrusion die. The die is a cross section of the extruded shape.

  Engineers design the extrusion die to produce the desired shape while being able to withstand the pressure on the aluminum billet without breaking itself. This is especially improtant for heat sink molds, as there are many fins that can come off the mold and fill the gaps in the fins. Excessive pressure on the fins can easily jam and destroy the mold.

  After the aluminum has been extruded, it is pulled along the beating table, where it is straightened and cooled. When originally manufactured, these bars can be hundreds of feet in length. Very long lengths need to be cut to more manageable lengths, usually around 8 feet, for ease of shipping and manufacturing.

  These aluminum profiles are then cut to length for the application in which they will be used. Any type of hole or other feature can be machined in the profile and customized as needed. Then process the surface finish like anodizing or painting to produce a finished extruded heat sink.
