What is industrial aluminum profile? Industrial aluminum profiles are aluminum rods that are hot melted and extruded to obtain aluminum materials with different cross-section shapes. The mechanical properties and application fields of the industrial aluminum profiles produced are also different with different proportions of addition. Industrial aluminum profiles in the industry generally refer to those in addition to doors and windows aluminum, building curtain wall aluminum profiles.

When it comes to the surface processing technology of industrial aluminum profile, it is necessary to make clear whether to change the structure of aluminum profile or surface processing technology. Generally speaking, the structure of aluminum profiles can be easily changed with CNC lathes. Milling, drilling, tapping, stamping, bending and other processes can be deeply processed, especially for aluminum shell and some mechanical parts.

The production process of industrial aluminum profiles is to obtain different sections of aluminum profiles by hot melt extrusion of aluminum rods. And industrial aluminum profiles have other surface treatment technology, roughly divided into the following kinds:

1. Sandblasting technology: The process of cleaning and rough metal surface under the impact of high speed air flow. The method can make the surface of industrial aluminum profiles obtain certain cleanliness and different roughness, improve the mechanical properties of the workpiece surface and improve the anti-fatigue properties of the profiles.

2. Polishing: Reduce the surface roughness of automobile aluminum parts by mechanical chemistry or electrochemical methods to obtain a smooth surface. Polishing technology is mainly divided into mechanical polishing, chemical polishing, electrolytic polishing.

3. Wire drawing: Metal drawing is the manufacturing technology of repeatedly scraping out aluminum sheet with sandpaper. Drawing is divided into linear drawing, random drawing, rotary drawing and thread drawing.

4. Anodic oxidation: Anodic oxidation refers to the electrochemical oxidation of metals. Aluminum and its alloy form an oxide film on aluminum products (anode) under the action of adding current under the corresponding electrolyte and specific technological conditions. Anodic oxidation can not only solve the defects of hardness and wear resistance of aluminum surface, but also extend the life of aluminum and improve the appearance of aluminum. In addition, some construction aluminum profiles using wood grain technology, electrophoresis technology, baking technology, etc., is the surface treatment technology widely used in industrial aluminum profiles in recent years.
