FACTORY  VIEW

The production process of Black Stained Anodized Aluminium Door Frame Extrusion is a process involving multiple delicate steps, mainly including the following key stages:

1. Pretreatment: First, the aluminum profile is thoroughly cleaned to remove oil, dust and other impurities on the surface. This step is crucial to the effect of subsequent treatment, because any residue may affect the quality of the oxide layer.

2. Machining: According to the design requirements, the aluminum profile is cut into the required length and shape, and the necessary drilling, milling and other processing are carried out to form the basic structure of the door frame.

3. Anodizing: The processed aluminum profile is placed in the electrolyte as an anode, and a porous aluminum oxide film is formed on its surface through electrolysis. This oxide film not only increases the hardness and wear resistance of the material, but also provides a good foundation for dyeing.

4. Dyeing treatment: After the oxide film is formed, the aluminum profile is immersed in a solution containing a specific dye, and the dye is penetrated into the micropores of the oxide film by electrochemical or chemical methods, so that the aluminum surface presents a uniform and deep black.

5. Sealing treatment: In order to enhance the corrosion resistance and wear resistance of the oxide film, the dyed aluminum profile needs to be sealed. This process usually uses boiling water or a special sealing agent to improve the overall performance of the material by sealing the micropores on the oxide film.

Compared with other metal materials, aluminum profiles have the following advantages:

1.Lightweight: The density of aluminum is about 1/3 of that of steel, which is convenient for transportation and installation.

2.High strength: Aluminum profiles that have been heat-treated and alloyed have high mechanical strength.

3.Corrosion resistance: The oxide film formed on the surface of aluminum gives it good corrosion resistance.

4.Easy to process: Aluminum profiles are easy to cut, weld and assemble, and can meet the needs of various complex structures.

With the advancement of science and technology and the continuous changes in people's aesthetic needs, the application prospects of Black Stained Anodized Aluminium Door Frame Extrusion are becoming more and more broad. In the future, we can expect more innovative surface treatment technologies and more diverse color options to meet the needs of different industries and consumers. At the same time, with the enhancement of environmental awareness, the research and development of more green and environmentally friendly production processes will also become an important direction for the development of the industry.
