Extrusion heat sink

Aluminum extrusions heat sink
High-Quality aluminum extrusions heat sink - Always Delivered On Time

Aluminum extrusion is the most common process for manufacturing heat sink. This process is cost-effective, and custom heat sink specifications can easily be manufactured. Producing heat sink from aluminum allows for significant weight savings and cost savings over copper.

Custom Extrusion Heat Sink Fabrication

If you already have a design for your extrusion heat sink, we can help you manufacture them according your design. Our extrusion facilities in China offer a wide range of capabilities to get you the heat sink extrusion, surface finish, and cnc machining you need.

Aluminum alloys

1. Alloy Selection

Aluminum alloys in the 6000 series have good thermal conductivity, are widely available, and are fairly strong. They tend to extrude well too. The most common alloys for extrusion heat sink are 6061 and 6063. Our extrusion facilities can extrude in these alloys or in the alloy of your choice. Let’s know alloy and temper you prefer.

Black anodizing

2. Surface Finishing

Our factory offer a range of finishing options. One of the most common surface finishes for heat sinks is anodizing. The anodizing electrochemical process increases surface emissivity, corrosion resistance, wear resistance, and electrical isolation. But coatings like paint or powder are not recommended because they will act as insulators. Heat sink can be anodized at our extrusion facilities with colored dyes. Let’s know the anodizing you prefer.

Post Machining & Secondary

3. Post Machining & Secondary

One way to help maximize the surface area of extrusion heat sink is by cross-cutting after extrusion. CNC machining is a very precise way to convert the fins on extrusion heat sink into pins. Pins help to maximize heat sink heat dissipation, making your heat sinks more effective. In addition, we can perform other secondary operations like drilling, milling, stamping, and cutting. Tell us about any secondary operations or machining your project may require. Please contact us.

We regularly post helpful content to help our design engineers and procurement professionals get the most out of their extrusion heat sink projects. Here are some helpful posts on the topic of aluminum extrusions heat sink.

Aluminum heatsink

Advantages of aluminium heat sink

Aluminum profile is pure aluminum or aluminum alloy as raw material, Various aluminum alloys include 6061, 6105, 6005, 6063, 6060, 6101, 1100 and 1350 alloys. The aluminum alloy after smelting, cutting, extrusion and other processes can form different section shape of the metal panel. And then can be cast in drawing, grooving, grinding, deburring, sandblasting, electroplating, radium screen printing, anodizing and other surface treatment processes can be fine surface, making heat sink enclosure with superior performance.

LED extruded aluminum heat sink

LED extruded aluminum heat sink manufacturing and features

LED extruded aluminum heat sink is formed by aluminum extrusion, and by CNC machining, embedded in heat pipe, and finally finished by surface treatment. Led aluminum heat sink is liquid aluminium formed through a fixed mold. Then cut the led heat sink aluminum profile and mchined into the desired shape. The post processing cost is high, and the heat sink fin can be made very thin to increase the heat dissipation area.
