Aluminum profile production process:
It mainly includes three processes of casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon coating, powder coating, wood grain transfer, etc.).
1. Melting and casting is the first process of aluminum production.
The main process is:
(1) Ingredients: Calculate the amount of various alloy components according to the specific alloy grades that need to be produced, and reasonably match various raw materials.
(2) Smelting: The prepared raw materials are added to the melting furnace for melting according to the process requirements, and the impurities and gases in the melt are effectively removed by degassing and slag refining means.
(3) Casting: The molten aluminum liquid is cooled and cast into various round casting rods under a certain casting process condition through a deep well casting system.
2. Extrusion:
Extrusion is the means of profile forming. Firstly, the mold is designed and manufactured according to the section of the profile product, and the heated round cast rod is extruded from the mold by an extruder. The commonly used grade 6063 alloy is also subjected to an air-cooling quenching process and an artificial aging process after extrusion to complete the heat treatment strengthening. Different grades of heat treatable reinforced alloys have different heat treatment regimes.
3. Coloring (here mainly on the oxidation process)
Oxidation: The extruded aluminum alloy profile has a low surface corrosion resistance and must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum. The high compartment aluminum profiles produced by the Jane's high compartment aluminum profile plant are almost all oxidized.
The main process is:
(1) Surface pretreatment: The surface of the profile is cleaned by chemical or physical means to expose a pure substrate to facilitate the obtaining of a complete and dense artificial oxide film. It is also possible to obtain a specular or matt (matte) surface by mechanical means.
(2) Anodizing: After surface pretreatment, under certain process conditions, the surface of the substrate is anodized to form a dense, porous, strong adsorption AL203 film.
(3) Sealing: The pores of the pores of the porous oxide film formed by anodization are closed, so that the oxide film is prevented from being contaminated, and the corrosion resistance and wear resistance are enhanced. The oxide film is colorless and transparent. By using the strong adsorption property of the oxide film before sealing, some metal salts are adsorbed and deposited in the pores of the film, so that the appearance of the profile shows many colors other than the natural color (silver white), such as black, bronze, Gold and stainless steel.

Aluminum extrusion profile features:
1. Corrosion resistance
The density of aluminum is only 2.7g / cm3, about 1/3 of the density of steel, copper or brass (7.83 g / cm3, 8.93 g / cm3, respectively). In most environmental conditions, including in the air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.
2. Conductivity
Aluminum is often used because of its excellent conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly twice that of copper.
3. Thermal conductivity rate
The thermal conductivity of aluminum alloys is about 50-60% of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and car cylinder heads and radiators.
4. Non - ferromagnetic
Aluminum is non-ferromagnetic, which is an important feature for the electrical industry and the electronics industry. Aluminum is not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.
5. Machinability
The machinability of the aluminum profile is excellent. Among the various deformable aluminum alloys and cast aluminum alloys, and in the various states that have been produced in these alloys, the machinability of the composites varies considerably, requiring special machine tools or techniques.
6. Formability
Specific tensile strength, yield strength, ductility and the corresponding work hardening rate dominate the change in allowable deformation.
7. Recycling
Aluminum has a very high recovery, the characteristics of recycled aluminum and native aluminum is almost no difference
