Industrial aluminum materials refer to all aluminum profiles other than building doors and windows, curtain walls, indoor and outdoor decorations, and building structures. When it comes to the processing method of industrial aluminum materials, we must first understand whether it is the structure of aluminum profile or the surface processing process.
Generally speaking, using CNC lathes can easily change the structure of aluminum profiles. Milling, drilling, attack wire, stamping, bending and other processes can be processed, especially suitable for aluminum shells and some mechanical structures. The production process of industrial aluminum is aluminum profiles that obtain different sections through hot -melt squeeze by aluminum rods. Industrial aluminum profiles also have other surface treatment processes, which are roughly divided into the following.
1. The process of cleaning and rough metal surfaces under the impact of high -speed airflow. This method can make the surface of the workpiece obtain a certain cleanliness and different roughness, improve the mechanical properties of the workpiece surface, and improve the anti -fatigue performance of the workpiece.
Second, polishing can reduce the surface roughness of the car aluminum through mechanical, chemical or electrochemical methods to obtain a bright and smooth surface. The polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing.
Third, drawing metal drawing is a manufacturing process for repeatedly scraping the aluminum plate with sandpaper. The drawing is divided into linear pull -up, random pull -pulling, rotating pulling and threading.
Fourth, anode oxidation anode oxidation refers to the electrochemical oxidation of metal. Under the corresponding electrolyte and specific process conditions of aluminum and alloys, under the action of adding current, an oxide film is formed on aluminum products (anode). The anode oxidation can not only solve the defects of aluminum surface hardness and abrasion resistance, but also extend the service life of aluminum and improve the beauty of aluminum. There are also some architectural aluminum profiles using wood grain technology, electrophoresis technology, baking process, etc. are some surface treatment processes that have been gradually adopted by industrial aluminum in recent years.
