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.






Material needs to meet the requirements of 5 aspects
1, Thickness: Aluminum alloy sliding door has 75 series, 88 series, 103 series, 120 series (series number represents the thickness of the frame thickness mm), the interior of the aluminum alloy sliding door usually use 88 series. The aluminum alloy window, there are 50 series, 55 series, 70 series, 76 series, 118 series/120 series, 130 series for options, should be based on the size of the window hole and the local wind pressure value, among them, used as a closed balcony aluminum sliding sash should not be less than 55 series.
2, Strength: Tensile strength should reach 157 Newtons per square meter and yield strength to 108 Newtons per square millimeter. When you purchase, you can hand moderate bending profile, let go after the restoration of the best.
3, Flatness: Check aluminum alloy surface, it should be no depression or bulging.
4, Gloss: aluminum doors and windows to avoid the purchase of open surface air bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects profiles.
5, Degree of oxidation: oxide film thickness should reach 10 microns. When you purchase light profile in the profile to see if the surface of the oxide film can be erased.
