Die-casting is made by melting aluminum alloy into a liquid state, filling it into a metal mold, and using a die-casting machine to directly die-cast to form a heat sink. The fin-shaped radiator in the common aluminum profiles for electrical & electronics
radiator can be formed by die-casting process, and can be made into complex shapes according to requirements, and the fins can be made into various three-dimensional shapes. The fins made are thin and dense, and have high dimensional accuracy, without seams, and can increase the heat dissipation area.
2. Baking paint
If the ordinary aluminum profiles for electrical & electronics heat sink is not subjected to surface processing, the surface will be rough, grainy, and burred, and the baking paint can completely block these drawbacks. By applying multiple primers and topcoats on the aluminum profile panel, and then baking it in a high temperature, the metal panel paint film after baking paint is uniform, full of color, smooth and clean, and no paint peeling phenomenon, which can help users to achieve individuality customized into various colors, the appearance is high-end and chic.
Wire drawing is to form fine lines on the metal surface by grinding, which can clearly show the fine silk marks, so that the metal panel has a fine luminous metalline luster, so that the product can have both technique and vogue elements.
Electroplating is a processing technology for aluminum profiles for electrical & electronics radiator to improve physical properties and appearance aesthetics. Electroplating is to coat a relatively thin metal coating on the surface of the aluminum profile. With the help of the coating, the wear resistance, corrosion resistance and oxidation resistance of the electronic radiator can be improved. In addition, if the metal coating with stronger thermal conductivity is used, it can be further improved. Improve the thermal conductivity and heat dissipation capacity of the electronic radiator.
Anodizing is actually similar to electroplating. Both add a protective layer on the surface of the aluminum profiles for electrical & electronics profile radiator. However, electroplating is to add a metal protective layer, while anodizing is to oxidize the surface of the aluminum alloy by electrochemical oxidation to form a protective layer type of oxide layer.
