One-stop solution for aluminum Heat Sink
We have 1000+ molds for aluminum radiators, and we can match your radiator project to reduce project costs without involving confidentiality agreements. With rich expertise in aluminum extrusion and precision CNC machining, we provide customized radiator solutions to meet your design needs (produced according to drawings).
Our own industrial park includes aluminum extrusion, CNC machining and surface treatment, covering the entire process of aluminum extrusion radiator production – from molds and extrusion to surface treatments such as anodizing, coating and finishing, with an aluminum extrusion tonnage of up to 5000 tons. Work with us to get tailor-made aluminum radiator solutions to maximize product quality and reduce project costs.
Aluminum radiator manufacturing process
With 12 years of experience in custom processing of aluminum profiles, we have accumulated 1000+ different aluminum radiators and a large number of radiator extrusion dies. We have established our own industrial park, which is equipped with extrusion production lines, CNC processing workshops and surface treatment workshops to provide one-stop production for aluminum radiators.
Molds and extrusions
Design a new mold according to the aluminum shell project drawing or use an existing mold, and then extrude the shell prototype through the aluminum extrusion process for further processing. (We will check our existing molds for your aluminum shell project, contact our sales staff for mold inspection to reduce costs.)
CNC machining
The required aluminum housing prototype can be directly processed by CNC processing, or the aluminum housing prototype obtained by aluminum extrusion can be further processed by drilling, grooving, etc.
Improve surface performance and aesthetics
Through surface treatment processes such as anodizing, sandblasting, and spraying, the performance of aluminum shell projects can be improved, corrosion resistance can be enhanced, and aesthetics can be improved.
Aluminum Heat Sink prices
Understand the cost and price of aluminum extruded radiators to provide a reference for your aluminum radiator project decision.
What does the price of aluminum extruded radiator include?
Usually the price of aluminum extruded heat sink includes mold cost (new molds require mold opening fees, existing molds usually charge a certain usage fee, our existing molds are free to use without involving confidentiality agreement), material cost, extrusion cost, CNC processing and surface treatment cost as required, and packaging and transportation cost.
How to reduce the cost of aluminum extrusion radiator project?
Based on the price analysis above, we can use molds, materials, additional CNC machining and surface treatment options to reduce costs, such as checking the manufacturer’s existing extrusion molds. Using existing molds can avoid the cost of new molds; project costs can also be reduced by ordering quantity. The cost per piece of mass production will be lower. It is worth considering placing an order when there is a long-term demand for your aluminum radiator project. Of course, you need to ensure the manufacturer’s production quality first.
Are there any other ways to reduce costs?
In addition to production costs, costs can be significantly reduced through design improvements and production feedback. Our team of engineers will evaluate your aluminum extrusion radiator project and provide suggestions for reducing production costs.

Aluminum radiator application scenarios
With its excellent thermal conductivity and lightweight characteristics, aluminum heat sinks effectively help equipment dissipate heat, ensuring its stability and extended service life during high-power operation.
LED lighting
LED lighting generates a lot of heat, and aluminum heat sinks provide effective heat dissipation solutions to maintain a stable operating temperature of the LED, ensuring that the lamps operate efficiently for a long time.
Car cooling
The battery pack and drive system of electric vehicles will generate a lot of heat during operation. Aluminum radiators can help dissipate heat and improve the overall efficiency and safety of the vehicle.
Electronic devices
When electronic equipment runs at high power or high frequency, it generates a lot of heat. The heat sink can effectively release the heat to avoid overheating that affects the performance and life of the equipment.
Advantages of Aluminum Extruded Heatsinks Compared to Other Materials
Excellent Thermal Conductivity with Lightweight Profile：
Aluminum offers a high thermal conductivity-to-weight ratio, making it ideal for efficient heat dissipation without adding unnecessary mass. This is especially valuable in applications where both cooling and weight control are critical, such as electronics and automotive components.
Cost-Effective for High-Volume Production：
Aluminum extrusion allows for rapid, repeatable manufacturing with relatively low tooling costs, especially compared to copper or die-cast options. It supports mass production with consistent quality.
Corrosion Resistance and Aesthetic Finish：
Aluminum forms a natural oxide layer, providing corrosion resistance even without surface treatment. It also offers flexibility for anodizing, painting, or powder coating to meet both protective and visual design needs.
Design Considerations for Aluminum Extruded Heatsinks
Optimize Fin Spacing and Thickness for Manufacturability and Performance：
The spacing and thickness of heat sink fins must be carefully optimized to balance thermal performance with production feasibility. If you have a preliminary design and wish to evaluate its manufacturability or control production costs, our engineering team is available to review and offer practical, cost-effective recommendations based on your specific requirements.
Consider Surface Area and Fin Complexity When Designing for Heat Dissipation：
The surface area of the fins plays a critical role in thermal efficiency. If your heat sink design includes contoured or non-flat fin surfaces, it becomes essential to maintain sufficient spacing between the fins. Excessively narrow spacing not only impairs airflow and reduces cooling performance, but also significantly increases manufacturing difficulty and cost.
Allow for Post-Machining if Necessary：
Design features like mounting holes, notches, or cutouts should be considered in advance and simplified when possible, to reduce secondary machining time and expense.
Surface Finishing Options for Aluminum Heatsinks
Anodizing (Clear or Black)：
Anodizing is the most common finish, enhancing corrosion resistance and surface hardness without significantly affecting thermal performance. Black anodizing can also improve radiative cooling under certain conditions.
Powder Coating and Painting：
These finishes are primarily used for aesthetic or protective purposes. However, thick coatings may reduce thermal efficiency slightly, so they are better suited for non-critical thermal applications.
However, due to the multi-fin structure of heatsinks, powder coating or spray painting often leaves certain areas uncoated or unevenly finished. As a result, this type of surface treatment is rarely considered for aluminum extruded heatsinks.
Aluminum extrusion radiator transport packaging
Each heatsink is individually wrapped with a protective paper or film layer to prevent surface scratches during handling and stacking. For additional cushioning, expanded polyethylene (EPE) foam and shrink film are applied to absorb impact and resist moisture.
