electronic products are developing rapidly, with more and more functions. With more functions, it is necessary to solve the problem of heat dissipation and ensure that the operation is not affected by high temperature. Then, what are the commonly used processing techniques for aluminum radiators

According to the different types and models of electronic products, the electronic aluminum heat sinks that need to be installed will vary in size and appearance specifications. Electronic radiator manufacturers must master mature electronic aluminum radiator molding technology in order to achieve special specificity, that is, to ensure that the high precision of electronic radiators can be matched with electronic products, and die casting tooling is commonly used in the production of electronic radiators. Craft. Die-casting molding is to melt aluminum alloy into a liquid state, fill it into a metal mold, and use a die-casting machine to directly die-cast it into a heat sink. The fin-shaped radiator in the common electronic aluminum profile radiator can be formed by die-casting process, and can be made into complex shapes according to requirements. The fins can be made into a variety of three-dimensional shapes. The fins made are thin and dense, with high dimensional accuracy. , No joints, and can increase the heat dissipation area. As the beginning of the electronic heat sink production process, die-casting molding technology can directly affect whether the radiator can match the electronic product, otherwise there will be errors. Even subsequent repairs are a very time-consuming and laborious project. In this process, the electronic heat dissipation Manufacturers must master precise mold making technology and skilled die-casting technology.

2. Paint

If the ordinary electronic aluminum heat sink is not surface processed, the surface will have roughness, particles, and burrs, and the baking varnish can completely cover these drawbacks. By applying primer and topcoat several times on the aluminum profile panel, and then baking it in high temperature, the metal Panel after the baking paint has a uniform paint film, full color, smooth and clean, and no paint drop phenomenon, which can help users achieve individuality Customized into various colors, the appearance is high-end and unique. Different from ordinary spray paint, the paint layer after baking is more stable, and will not cause the paint to soften and fall off due to long-term high temperature when helping electronic products to dissipate heat.

3. Drawing

Drawing Die casting parts

The paint can be created for the appearance color of the electronic aluminum profile radiator, but it covers the metallic luster of the aluminum profile panel. If you want to retain the metal texture of the electronic aluminum profile radiator and look beautiful, the drawing process is the best Solution. Wire drawing is to form fine lines on the metal surface by grinding, which can clearly show the fine wire marks, so that the metal panel will have a fine luminous metallic luster, so that the product can have both technology and fashion elements.

Electroplating Die Casting Products

Electroplating is a processing technology for electronic aluminum radiator(after cnc machining and die casting process ) to improve physical performance and enhance appearance. Electroplating is to plate a relatively thin metal coating on the surface of aluminum profiles. 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 and heat dissipation capacity of the electronic radiator. Of course, the electroplating coating does not only play a role in protecting and improving the heat dissipation performance, but can also play a decorative role. In the case of coins, electroplating is used on its outer layer, which can enhance the metallic luster of the surface with the help of electroplating, and has a smooth and delicate touch. Through this process, the purpose of enhancing performance and aesthetics can be achieved at the same time, which is a very scientific and economical processing method for electronic radiator manufacturers.

Anodizing Die Casting Products

Anodizing is actually similar to electroplating. Both add a protective layer to the surface of the electronic aluminum profile radiator. However, electroplating is to add a metal protective layer, while anodizing uses electrochemistry to oxidize the surface of the aluminum alloy to form protection. Type of oxide layer. Both can enhance the surface aesthetics and wear resistance of electronic radiators, but the most commonly used in the production of electronic aluminum profile radiators is anodizing, because the surface of the electronic radiator after oxidation is more refined and beautiful, and the performance is more stable, and With the help of oxidation, the surface of the electronic radiator can be oxidized into various colors, which broadens the ability of the electronic radiator manufacturer to shape the appearance.
