In daily life, aluminum profiles can be seen everywhere. Industrial aluminum profiles generally refer to all aluminum profiles except for building doors and windows, curtain walls, interior and exterior decoration and aluminum profiles for building structures. The aluminum profile processing process includes three whole processes: melting, extrusion and coloring (coloring keys include: oxidation, electrophoresis, fluorocarbon spray painting, electrostatic powder spraying, wood grain transfer, etc.).

Melting is the first process of aluminum profile processing and manufacturing

(1) Seasoning: According to the actual aluminum alloy model that must be produced, calculate the added amount of various aluminum alloy components, and effectively match various raw materials.

(2) Smelting: The selected raw materials are added to the smelting furnace for melting according to the requirements of the processing technology, and the slag and vapor in the melt are reasonably removed according to the methods of degassing and slag discharge refining.

(3) Forging: The smelted lithium bromide solution is refrigerated and cast into round cast bars of various specifications and models under certain forging process standards and according to the deep water well forging system software.

Extrusion is the second process of aluminum alloy processing

Extrusion is the way that aluminum profiles are processed and formed. First, according to the design plan of the cross-section of the profile product, the abrasive tool is produced, and the heated round cast bar is extruded from the abrasive tool by an extruder. The common type 6063 aluminum alloy also uses a whole process of air-cooled heat treatment and the whole process of artificial aging after extrusion to strengthen the heat treatment process. Different types of heat-treatable process-enhanced aluminum alloys have different heat-treating process rules and regulations.

Coloring is the third process of aluminum alloy processing

Anodizing: Anodizing is one of the important steps in the processing of aluminum profiles. The surface of the extruded aluminum alloy profiles is not strong in corrosion resistance. Surface solutions must be carried out according to anodizing to improve the corrosion resistance and wear resistance of aluminum profiles. and the beauty of the surface.

(1) Surface preparation treatment: The surface of the profile is cleaned by means of organic chemistry or physics, exposing the pure routine, in order to obtain a detailed and high-density human oxide film. Mirror glass or matt (matt) surfaces can also be obtained depending on the mechanical means.

(2) Anodizing: Under certain processing technology standards, the surface of the pre-treated profile is anodized on the conventional surface and transformed into an AL203 film with high density, porous structure and strong adsorption.

(3) Grouting reinforcement: The porosity of the porous structure oxide film converted into the anodized film is closed, which improves the pollution control, corrosion resistance and wear resistance of the oxide film. The oxide film is completely transparent without color. The strong adsorption force of the oxide film before grouting reinforcement is used to absorb and accumulate some metal salts in the film pores, so that the surface of the profile can show many tones other than the primary color (silver), such as: gray Black, copper, orange and stainless steel.

The precision of the processing of aluminum profiles is far more than what we have mentioned above. There are also various treatments such as finishing, sealing, anodizing, etc. to produce a complete aluminum profile. Of course, I would like to know more about the processing of aluminum profiles. Let's take a look at the processing technology of aluminum profiles with the friends of the process and method. How are aluminum profiles processed? It can be divided into the following aluminum alloy processing processes:

1. Casting. Aluminum profile is an aluminum alloy product, so first add aluminum ingots and magnesium and other metals into the smelting furnace in proportion to obtain aluminum liquid, and pass the aluminum liquid through the casting process to obtain aluminum rods of different specifications.

2. Extrusion. According to the aluminum profile molds of different sections, the aluminum rods are extruded into finished aluminum profiles of different specifications.

3. Straighten. The straightness of the aluminum profile affects whether the aluminum profile can be used on mechanical equipment, so the straightness of the aluminum profile is up to standard, which is one of the important standards for the quality of the aluminum profile. Generally, the extruded profiles need to be straightened.

4. Surface treatment. Generally, the surface of aluminum profiles is treated with anodized silver white, which is elegant, beautiful and anti-corrosion. This step is generally done, and after cooling, the finished aluminum profile comes out.

Take the aluminum profile frame as an example, the formation of a frame can be roughly divided into three parts, the first is the formation of the aluminum profile, then the processing of the aluminum profile, and then the assembly, and a series of processes are completed.

The processing of aluminum profiles includes its own formation and deep processing. For aluminum profiles, aluminum ingots and other metal elements are first added to the smelting furnace, and aluminum rods are formed through the casting process. Then use an extruder to extrude finished aluminum profiles of different specifications, and then perform straightness correction, and then surface treatment. In this way, the finished aluminum profiles come out. Let's talk about how aluminum profiles are processed, including sawing, drilling, tapping, milling, etc. The sawing is because the length required by each customer is different. Generally, the profiles are 6 meters long. The steps are also operated according to the drawings. The deep processing needs the blessing of the instrument, the accuracy will be better, and the size deviation will be small.
