Industrial aluminum profiles have unparalleled excellent properties such as corrosion resistance, dirt resistance, environmental protection, and good tensile performance compared to other metals. Therefore, industrial aluminum profiles have been widely used in various fields such as construction, transportation, and aviation in recent years. We often see the use of industrial aluminum profiles in our daily lives. Do you know how industrial aluminum profiles are produced and manufactured? Next, we will talk about the specific processing process of industrial aluminum profiles.

Casting is the first process in aluminum production. Ingredients: Calculate the amount of various alloy components added based on the specific alloy grade required for production, and reasonably match various raw materials. Melting: The prepared raw materials are added to the smelting furnace according to the process requirements for melting, and the impurities and gases in the melt are effectively removed through degassing and slag refining methods. Casting: The melted aluminum liquid is cooled and cast into various specifications of round cast rods through a deep well casting system under certain casting process conditions.

Squeeze. Extrusion is a means of forming profiles. First, design and manufacture a mold based on the cross-section of the profile product, and use an industrial aluminum profile extruder to extrude the heated round cast rod from the mold.

Oxidation. The surface corrosion resistance of extruded aluminum alloy profiles is not strong, and surface treatment through anodizing is necessary to increase the corrosion resistance, wear resistance, and aesthetic appearance of the aluminum material.

The main process is surface pretreatment, which involves cleaning the surface of the profile using chemical or physical methods to expose a pure substrate, in order to obtain a complete and dense artificial oxide film.

Anodizing refers to the process in which the surface of a pre treated profile undergoes anodizing on the substrate surface under certain process conditions, resulting in a dense and porous film layer.

Sealing pores refers to sealing the pores of the porous oxide film generated after anodizing, enhancing the anti pollution, corrosion resistance, and wear resistance of the oxide film. The oxide film is colorless and transparent. By utilizing the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores, which can make the surface of the profile show many colors beyond its natural color.
