As precision parts, custom heat sinks are widely used in various fields, and their structure and quality have an indispensable influence on the heat dissipation effect. This requires custom heat sink manufacturers to strive for excellence in material selection and surface treatment. Scientific and efficient surface treatment technology can not only help aluminum heat sink manufacturers save costs, but the custom aluminum heat sinks produced are more cost-effective and have a better aesthetic effect. They also play an important role in building their own brands.
As a manufacturer of high-end precision heat sinks, Shengyida has put an end to rough manufacturing. In addition to the fine selection of materials, the surface treatment process is more down-to-earth and stable. After sandblasting, wire drawing, paint baking, electroplating, anodizing and laser, etc., The final product is beautiful and exquisite, durable, and efficient in heat dissipation. Let's follow the footsteps of Xiaobian to learn more about these crafts.
1. Sandblasting
Sandblasting is a process of cleaning and roughening the surface of the heat sink by using compressed air as the power and the impact of the high-speed sand flow. Through impact and cutting, this process can not only remove all kinds of dirt such as rust on the surface of the heat sink, make the surface of the product show a uniform and consistent metallic luster, but also improve the mechanical properties of the heat sink surface and improve the resistance of the heat sink. Fatigue performance.
2. Stretch
When drawing the surface, it is a surface treatment method that forms light lines on the surface by grinding the product to achieve a decorative effect. Using this process can make the heat sink highlight the texture of the metal material and make it more beautiful and exquisite. At the same time, for the heat sink, this is also a good way to increase the heating area of the heat sink and improve work efficiency.
3. Paint
That is, a high-performance special coating called Teflon is added to the surface of the heat sink through high temperature (temperature between 280°C—400°C), so that the surface of the heat sink is non-sticky, heat-resistant, moisture-resistant, and wear-resistant. Corrosion resistance and other characteristics. Compared with the traditional painting process, baking paint has more advantages in terms of aesthetics and thermal conductivity.
4. Gilded
Using the principle of electrolysis, a thin layer of other metals or alloys is plated on the metal surface of the heat sink. This additional layer of the metal film process can prevent the surface of the heat sink from oxidation, and enhance wear resistance, conductivity, reflection, and corrosion resistance. , Improve appearance, etc. This process of plating a protective layer and a decorative layer on the metal surface is very economical and scientific for manufacturers.
5. Anodizing
Anodizing is the most widely used and most successful process in modern surface treatment processes, and Chicco is one of the few manufacturers capable of anodizing. In a sulfuric acid environment, anodic oxidation usually forms an oxide film on the surface of the heat sink by applying an electric current. Compared with the traditional electrostatic spray powder, anodizing does not affect the heat dissipation effect of the heat sink, thus effectively overcoming the lack of surface hardness and wear resistance of aluminum alloy, so it is favored by manufacturers.
6. Laser processing
Laser processing is also laser processing, which uses a high-energy-density beam to irradiate the surface of the material to process the shape of the custom heat sink. Because it is non-contact processing, there is no direct impact on the material, the processing speed is fast, and the cut is complete, which helps manufacturers effectively reduce material loss and ensures the high precision and high quality of the finished product.
Don't accumulate steps for thousands of miles, don't hone meticulously to make a good product. Shengyida will treat every process with the most rigorous attitude, use the most complete process to produce each product, and is committed to creating high-end and exquisite heat sinks and becoming a leader in the heat sink industry.
