Common processing technology of shell Heatsink production
Electronic products are developing rapidly, and are developing towards a lighter and thinner body and superior performance. In order to achieve this goal, electronic manufacturers must first solve the problem of heat dissipation of electronic products, that is, let electronic products dissipate heat faster and more efficiently in a shrinking space, so as to ensure that the operation is not affected by high temperature. Configuring electronic radiator shell for electronic products is a basic and effective method to solve heat dissipation.
In order to make the electronic heat sink with good quality and excellent performance, we need not only excellent aluminum alloy materials, but also professional and exquisite processing technology.
Die Casting:
Die casting is to melt the aluminum alloy into liquid, fill it into the metal tooling , and use the die-casting machine to directly die-casting to make the heat sink. The fin radiator among the common electronic radiators can be formed by die-casting process. It can be made into complex shapes according to the needs. The fins can be made into a variety of three-dimensional shapes. The fins are thin and dense, with high dimensional accuracy, no joints, and can increase the heat dissipation area.
Baking Paint:
Without surface treatment processing, the surface will be rough, with particles and rough edges, and the baking paint can completely cover these disadvantages. By applying primer and finish paint on the aluminum profile panel for several times, and then baking at high temperature, the paint film of the metal panel after baking is uniform, full of color, smooth and tidy, and there is no paint falling phenomenon, which can help customers customize various colors and have a high-end and unique appearance. Different from ordinary painting, the paint layer after baking is more stable and will not soften and fall off due to long-term high temperature when helping electronic products to dissipate heat.
Wire Drawing:
Wire drawing is to form fine lines on the metal surface by grinding, which can clearly show fine wire marks, so as to make the metal panel exude fine luminous metal luster and obtain better flatness.
Nickel Plated:
Nickel plating is a processing technology to improve the physical properties and appearance of electronic radiator. Electroplating is to coat a thin metal coating on the surface of aluminum profile, which can improve the wear resistance, corrosion resistance and oxidation resistance of electronic radiator.
Anodizing:
Anodizing is similar to electroplating, which adds a protective layer to the surface of electronic radiator, but electroplating adds a metal protective layer, while anodic oxidation oxidizes the surface of aluminum alloy with the help of electrochemistry to form a protective oxide layer. Both of them can enhance the surface beauty and anti loss performance of the electronic radiator, but anodizing is commonly used in the production of aluminum profile electronic heatsink , It widens the ability of electronic radiator manufacturers in shaping appearance.
Heatsink production should not only have a systematic and perfect production and processing process, but also be able to skillfully use different processing technologies according to the needs of different customers, so as to produce products with impeccable quality and performance.
