In daily life, aluminum profiles can be seen everywhere. Industrial aluminum profiles generally refer to all aluminum profiles except those used for building doors and windows, curtain walls, indoor and outdoor decoration and building structures. The aluminum profile processing process includes three whole processes: melting, extrusion and coloring (coloring key includes: oxidation, electrophoresis process, fluorocarbon painting, electrostatic powder spraying, wood grain transfer printing, etc.).
Aluminum alloy processing parts
1、 Melting is the first process of aluminum profile processing and manufacturing:
(1) Seasoning: Calculate the added amount of various aluminum alloy components according to the actual aluminum alloy model that must be manufactured, and effectively match various raw materials.
(2) Smelting: add the selected raw materials into the smelting furnace for melting according to the processing technology regulations, and reasonably remove the impurities and vapors in the solution according to the degassing and slag discharging refining methods.
(3) Forging: under certain forging process standards, the melted lithium bromide solution can be refrigeration cast into round cast rods of various specifications and models according to the deep water well forging system software.
2、 Extrusion is the second process of aluminum alloy processing:
Extrusion is the way of processing aluminum profiles. First, according to the cross section design scheme of profile goods, the grinding tool is manufactured, and the heated round cast rod is extruded from the grinding tool by an extruder. For the common 6063 aluminum alloy, the whole process of air cooling heat treatment and artificial aging after extrusion is also used to strengthen the heat treatment process. The rules and regulations of heat treatment process for different types of heat treatable reinforced aluminum alloys are different.
Aluminum alloy processing coloring
3、 Coloring is the third process of aluminum alloy processing:
Anodizing: Anodizing is one of the important steps in the processing of aluminum profiles. Extruded aluminum alloy profiles have poor surface corrosion resistance. Surface treatment must be carried out according to anodizing to improve the corrosion resistance, wear resistance and surface beauty of aluminum profiles.
(1) Surface preparation: clean the profile surface with organic chemistry or physics to expose pure convention, so as to obtain detailed and high-density manual oxide film. Mirror glass or matte surface can also be obtained according to mechanical equipment.
(2) Anodic oxidation: under a certain processing standard, the profile after surface preparation will produce anodic oxidation on the conventional surface, which will be converted into a layer of high-density, porous and highly adsorptive AL203 film.
(3) Grouting reinforcement: the membrane pore porosity of the porous structure oxide film converted from anodic oxidation is closed, so as to improve the pollution control, corrosion resistance and wear resistance of the oxide film. The oxide film has no color and is completely transparent. The strong adsorption of the oxide film before grouting reinforcement is used to absorb and accumulate some metal salts in the film hole, which can make the profile surface show many colors other than the primary color (silver color), such as gray black, copper, orange yellow and stainless steel plate color.
The process precision of aluminum profile processing is far more than what we have mentioned above. A complete aluminum profile can only be produced by finishing, sealing, anodizing and other treatments. Of course, partners who want to know more about the process and methods of aluminum profile processing will look at the aluminum profile processing technology together. How are aluminum profiles processed? It can be divided into the following aluminum alloy processing processes:
1. Melt casting. Aluminum profile is an aluminum alloy product, so first add aluminum ingot, magnesium and other metals into the smelting furnace in proportion to obtain aluminum liquid, and then through the casting process, aluminum rods of different specifications can be obtained.
2. Extrusion. According to the aluminum profile dies with different sections, the aluminum rods are extruded into aluminum profile products with different specifications.
3. Straightening. The straightness of aluminum profiles affects whether aluminum profiles can be used on mechanical equipment, so the straightness of aluminum profiles up to standard is one of the important standards for the quality of aluminum profiles. Generally, the extruded profiles need to be straightened for straightness.
4. Surface treatment. The surface of general aluminum profiles is treated with anodized silver white, which is elegant, beautiful and corrosion resistant. Generally, after this step is completed, the finished aluminum profiles will come out after cooling.
Take the aluminum profile frame as an example. The formation of a frame can be roughly divided into three parts. First, the formation of aluminum profiles, then the processing of aluminum profiles, and then the assembly. A series of processes are completed.

Aluminum profile processing includes its own formation and deep processing. Aluminum ingots and other metal elements are first added to the smelting furnace to form aluminum bars through the casting process. Then use the extruder to extrude the finished aluminum profiles of different specifications, and then correct the straightness, followed by the surface treatment, so that the finished aluminum profiles can be produced. Let's talk about how aluminum profiles are processed, including sawing, punching, tapping, and milling. Sawing is because each customer requires a different length. Generally, profiles are 6 meters long. The subsequent steps are also based on the drawings. Further processing requires the support of instruments, which will improve the accuracy and reduce the size deviation.
