Industrial aluminum profiles have unparalleled excellent properties such as corrosion resistance, dirt resistance, environmental protection, and good tensile properties. Therefore, industrial aluminum profiles have been widely used in various fields such as construction, transportation, and aviation in recent years. We can often see the use of industrial aluminum profiles in daily life. Do you know how industrial aluminum profiles are manufactured? The following is from Dongguan Lianxin Hardware Co., Ltd. to talk about the specific processing process of industrial aluminum profiles.

Casting is the first process of aluminum production. Ingredients: According to the specific alloy grade to be produced, calculate the addition amount of various alloy components, and reasonably match various raw materials. Smelting: The prepared raw materials are added to the melting furnace for melting according to the process requirements, and the slag and gas in the melt are effectively removed by means of degassing and slag refining. Casting: Under certain casting process conditions, the smelted aluminum liquid is cooled and cast into round cast rods of various specifications through a deep well casting system.

extrusion. Extrusion is a means of profile forming. First, the mold is designed and manufactured according to the cross-section of the profile product. The industrial aluminum profile extruder is used to extrude the heated round cast rod from the mold.

Oxidation. The extruded aluminum alloy profile has poor surface corrosion resistance and must be surface-treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum material.

The main process is: surface pretreatment, using chemical or physical methods to clean the surface of the profile, exposing the pure matrix, in order to obtain a complete and dense artificial oxide film.

Anodization, the surface pre-treated profile, under certain process conditions, anodization occurs on the surface of the substrate, resulting in a dense, porous film layer.

Sealing, so-called sealing is to close the pores of the porous oxide film formed after anodizing, so that the oxide film has enhanced anti-pollution, corrosion resistance and wear resistance. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film pores, which can make the appearance of the profile show many colors other than the original color.
