Product details

The manufacturing process of aluminum radiators involves multiple steps, from material selection to finished product inspection, and each step requires precise control to ensure the quality and performance of the final product. The following is the basic process of aluminum radiator manufacturing:

Aluminum alloy	6061,6063 Aluminum Heat Sink
Temper	T5,T6
Standard	GB5237.1-2017
Surface treatment	Mill finish, Sandblasting, Anodizing, Electrophoresis, Polishing, Power coating, PVDF coating, Wood transfer, etc.
Color	Customized
Thickness	Customized
Payment terms	30% deposit, 70% balance before shipping by T/T; L/C at sight

1. Material preparation

Material selection: Aluminum alloy is usually used because it has good thermal conductivity and machinability.

Cutting: Cutting aluminum ingots or aluminum sheets to the appropriate size and shape according to the design specifications. Aluminum Anodizing

Step 2 Form

Extrusion molding: This is one of the most common methods of manufacturing aluminum radiators. The desired heat sink shape is formed by placing the heated aluminum alloy into the mold and applying high pressure to push it through the mold opening.

Die casting: For some radiator with complex structure, die casting process can be used. This method is suitable for making products with complex internal structures.

Stamping: Suitable for thin-wall, large-area heat sink manufacturing, low cost but limited scope of application. Aluminium Extrusions

3. Surface treatment

Anodizing: In order to improve corrosion resistance and aesthetics, aluminum radiators are usually anodized. This process forms a hard oxide film on the surface of the aluminum.

Plating or spraying: Sometimes additional protective layers or colors are added by plating or spraying.

Step 4 Assemble

If the radiator consists of multiple parts, it needs to be assembled. This may include steps such as fixing fans, installing heat pipes, and so on.

5. Quality inspection

Performance test: Test whether the heat dissipation efficiency meets the standard.

Physical inspection: Confirm that there are no defects, deformations or other quality problems. Aluminum Cutting

Environmental adaptability testing: such as corrosion resistance testing, etc., to ensure that the product can operate stably in the expected working environment.

Matters needing attention

In the manufacturing process, the quality of each link must be strictly controlled, especially the selection of materials and the molding process, which is crucial to ensure the final performance of the radiator. In addition, with the development of technology, new manufacturing technologies and materials continue to emerge, further improving the performance and application range of aluminum radiators.
