If the material is compared to the "body" of the product, then the surface treatment is undoubtedly the "skin" of the product. It has a significant impact on the appearance and beauty of the product. Whether it is the mobile phones and computers we use daily, or various smart products and household appliances, the high-cold and delicate sense of technology presented by their appearance is inseparable from the careful creation of surface treatment. So, how is this magical effect achieved? Next, let us explore the secrets of anodizing together.

Anodizing, a magical process of electrochemical reaction, can put on a solid "armor" for aluminum alloy products. It carefully builds a uniform and dense oxide film on the surface of the aluminum alloy through electrolytic oxidation. This film not only has excellent protective performance, but also can significantly improve the wear resistance, corrosion resistance and electrical insulation performance of aluminum alloy products.

Create a technological "new outfit" for aluminum alloy

The anodizing process not only builds a solid protective layer for aluminum alloy, but also gives it a colorful appearance. Through dyeing technology, parts can present a variety of different colors, except white, which greatly enhances the decorativeness of the product. This technology complements the metallic texture of aluminum alloys and creates a new image full of technological charm for aluminum alloy products.

In addition, anodizing is divided into two types: matte and glossy. The glossy surface has excellent reflective effect, the light is clear and bright, which significantly improves the appearance of the product and is often used in the production of fine products and decorations. The matte surface has a low reflectivity, the light is blurred and not obvious, provides a soft light feeling, and is not easily affected by scratches and pollution. Therefore, it is often used for metal products that require a soft light feeling, anti-pollution and not easy to scratch.

Next, we will explore some common problems of anodizing.

These include the differences between ordinary anodizing, hard anodizing and conductive oxidation.

The above three anodizing methods all have the effect of preventing natural oxidation, but they are different in specific characteristics. Ordinary anodizing provides good wear resistance and insulation, and is easy to color and has rich color options, which is very suitable for products that require decorativeness. Hard anodizing is more resistant to wear and has ideal insulation properties. Its surface is harder after treatment. However, please note that its color selection is relatively limited, and light colors (such as natural color and black) may not be applicable, so it is more suitable for products with high functional requirements, such as cylinders, transmission parts, and military products. Conductive oxidation is known for its superior conductivity, but it should be noted that it is not wear-resistant and does not support dyeing, so it is often used in specific electrical and electronic devices, such as electrolytic capacitors, integrated circuits, and semiconductor devices.

Next, let's explore why Oxidation uses sandblasting-120 mesh surface treatment by default. This treatment method may be to meet the needs of specific products and provide the required surface characteristics. But please note that this does not mean that other anodizing methods are not applicable or have no advantages. The specific treatment method should be determined according to the actual needs and characteristics of the product.

Sandblasting has many functions, including degreasing, deburring, derusting, de-scratching, and de-scratching. It can effectively improve the uniformity of oxidation color and enhance the appearance of the product. Jiali Chuang Oxidation uses sandblasting by default, aiming to provide customers with a better processing experience. However, this treatment method may sometimes produce slight sand marks on the micropores, affecting their use (for example, for threaded holes smaller than M2 or blind holes smaller than 2MM). If your processing needs have special requirements for smoothness, such as fine holes, fine shafts or gear surfaces, you can make a special note when placing an order and request not to perform sandblasting. At the same time, too thin workpieces may be severely impacted and deformed during the sandblasting process, so we recommend increasing the workpiece thickness to more than 5MM, or clearly stating that sandblasting is not required when placing an order.
