What are the general aspects of aluminum profile processing technology?

Aluminum profile processing melting casting is the first process of aluminum production, ingredients according to the need to produce the specific alloy brand, calculate the amount of various alloy components, reasonable collocation of various raw materials.

Smelting

According to the process requirements, the prepared raw materials are added to the melting furnace to melt, and the impurities and gases in the melt are effectively removed by means of degassing, slagging and refining.

cast

Under certain casting process conditions, the molten aluminum is cooled and cast into various specifications of round casting rods by deep well casting system.

extrusion

Extrusion is a means of forming profiles. First, according to the section design of the profile product, the mold is produced, and the heated round casting rod is extruded from the mold by an industrial Aluminum Extrusion machine.

oxidation

The surface corrosion resistance of extruded aluminum alloy profiles is not strong, and the surface treatment must be carried out by anodizing, and the corrosion resistance, wear resistance and appearance are beautiful.

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

Under certain technological conditions, the surface of the substrate is anodized to form a dense, porous film.

Sealing hole, the so-called sealing hole, is the pores of the porous oxide film produced after sealing anodic oxidation, enhancing the anti-pollution, corrosion resistance and wear resistance of the oxide film.

The oxide film is colorless and transparent, and the strong adsorbability of the oxide film before sealing is used to adsorb and deposit some metal salts in the film holes, which can make the appearance of the profiles show many colors.
