Talking about aluminum profiles

Aluminum profiles are aluminum rods that are hot-melted, extruded, and thus obtain aluminum materials with different cross-sectional shapes.

First, according to purpose can be divided into the following categories:

1. Doors and windows of architectural aluminum doors and windows (divided into two kinds of doors and windows and curtain wall).

2. Special radiator aluminum profile for CPU radiator

3. The aluminum alloy shelf aluminum profiles, their difference lies in the different cross-sectional shapes, but are produced by hot melt extrusion.

4. Industrial aluminum profile: It is mainly used for the automation machinery equipment, the skeleton of the enclosure and various companies to customize the mold according to their own mechanical equipment requirements, such as assembly line conveyor, hoisting machine, dispenser, testing equipment, etc., electronic machinery Industry and clean rooms are used mostly!

Second, according to alloy classification:

Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other award winning aluminum profiles, 6 series is more common. The difference between different brands is the ratio of various metal components is not the same, in addition to the commonly used doors and windows Aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, industrial aluminum profiles without a clear model distinction, most of the production plants are processed in accordance with the customer's actual drawings.

Third, according to the surface treatment requirements classification:

Anodized aluminum

2. Electrophoretic coating of aluminum

3. Powder coating aluminum

Wood grain transfer aluminum

5. Planed aluminum (divided into two types of mechanical planing and chemical polishing, in which the chemical polishing cost is higher and the price is more expensive)

Including casting, extrusion and coloring (coloring includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder coating, wood grain printing, etc.) three processes.

1. Casting is the first process of aluminum production.

The main process is:

(1) Ingredients: According to the specific winning prizes required to be produced, the amount of each alloy component added is calculated and properly matched with various raw materials.

(2) Smelting: The prepared raw materials are added into the smelting furnace according to the process requirements to be melted, and the impurities and gases in the melt are effectively removed through degassing and deslagging refining means.

(3) Casting: The smelted aluminum liquid is cooled and cast into a variety of round cast rods under a certain casting process condition through a deep well casting system.

2. Extrusion: Extrusion is a means of forming a profile. First, molds were designed and manufactured according to the profiles of the profile products, and the heated round cast rods were extruded from the mold using an extruder. Commonly used grade 6063 alloy, when used in the extrusion also uses an air-cooled quenching process and artificial aging process to complete the heat treatment. Different brands of heat treatable alloys have different heat treatment regimes.

3, coloring (here first talk about the oxidation process)

Oxidation: Extrusion of aluminum alloy profiles, the surface corrosion resistance is not strong, must be surface treatment by anodizing to increase the aluminum corrosion resistance, wear resistance and appearance of the appearance.

Its main process is:

(1) Surface pretreatment: The surface of the profile is chemically or physically cleaned to expose a pure matrix to facilitate obtaining a complete, dense artificial oxide film. It is also possible to obtain a specular or matt (matte) surface by mechanical means.

(2) Anodizing: After surface pretreatment of the profiles, anodization occurs on the surface of the substrate under certain process conditions to form a dense, porous, strong AL203 film layer.

(3) Sealing: The pores of the pores of the porous oxide film formed after the anodization are closed, so that the oxide film is prevented from contamination, corrosion and abrasion resistance. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores, which can make the appearance of the material besides the colors (silver white), such as: black, bronze, Gold and stainless steel and so on.
