What is the Aluminum Profile?
Aluminum profiles are also called aluminum alloy profiles, but it is not aluminum alloy, you can simply understand that the biggest difference between aluminum alloy and aluminum profiles is that the form is not the same, aluminum alloy is a kind of material, but aluminum profiles are products that have been processed, and can be used directly.
First understand the formation of aluminum profile, first is aluminum ingot / aluminum bar through the melting and casting, and then through the mold extrusion of the desired shape, and finally by the surface treatment of these three processes. Thus, aluminum profiles with different cross-section shapes are obtained. Aluminum ingots, aluminum rods, is the most primitive material of all aluminum profiles, the general length of 8-12 meters, with a diameter of D90mm, D105mm, D120mm, D178mm, the four kinds, at present the most conventional is 6061/6063 alloy.

Classification of Aluminum Profiles
Finished aluminum profiles, can be divided into two categories, one is the construction of aluminum profiles, mainly used in our daily life, such as aluminum doors and windows, aluminum curtain wall in our lives can be seen everywhere.
the other is the industrial aluminum profiles, mainly used in industrial production and manufacturing, such as automated machinery and equipment, the skeleton of the protective cover, as well as the companies according to their own machinery and equipment requirements for custom molding, such as assembly lines Conveyor belts, elevators, dispensing machines, testing equipment, shelves and so on, electronic machinery industry and clean room used mostly!
Production Process of the Aluminum profile
1.Melting and casting is the first process of aluminum production, the main process for the ingredients, melting, casting.
(1) batching: according to the need to produce specific co*** number, calculate the amount of various alloy components added, reasonable with a variety of raw materials.
(2) smelting: the raw materials will be good according to the process requirements into the melting furnace melting, and through the de-gassing, de-slagging refining means of the melt within the slag, gas effectively removed.
(3) casting: melted aluminum in a certain casting process conditions, through the deep well casting system, cooling casting into various specifications of the round cast bar.
2. Extrusion is the means of profile molding, first through the sectional design to create a mold, and then use the extruder will be heated round cast bar from the mold extrusion molding. Commonly used grade 6063 alloy, in the extrusion also use an air-cooled quenching process and its subsequent artificial aging process, in order to complete the heat treatment strengthening. Different grades of heat-treatable strengthened alloy, its heat treatment system is different.
3. The surface treatment is the profile surface treatment, generally commonly used is anodic oxidation of aluminum, presenting people with a sand surface, bright white and oxidation coloring of the surface visual effects.
(1) surface pretreatment: chemical or physical methods of cleaning the surface of the profile, bare pure matrix, in order to facilitate the acquisition of complete, dense artificial oxide film. Can also be obtained by mechanical means mirror or no light (matte) surface.
(2) Anodic oxidation: After the surface pretreatment of the profile, under certain process conditions, the substrate surface anodic oxidation occurs, generating a layer of dense, porous, strong adsorption of Al2O3 film layer.
(3) sealing hole: the porous membrane pores of the porous oxide film generated after anodic oxidation are closed, so that the oxide film is anti-pollution, corrosion and wear-resistant performance is enhanced. The oxide film is colorless and transparent, using the strong adsorption of the oxide film before sealing the holes, adsorption and deposition of some metal salts in the membrane holes, which can make the appearance of the profile to show the color (silver-white) other than the color of many colors, such as: black, bronze, gold and stainless steel color and so on.
CNC deep processing of aluminum profiles
CNC refers to CNC machine tools programmed and controlled by the CNC machining language for positional coordinates, tool feed speed, spindle speed, tool changer, coolant, and so on. Unnecessary parts are removed by arbitrary programming, drilling, tapping, milling, cutting, etc. in one step.
Advantages between CNC machined aluminum profiles
1. High strength
Aluminum and aluminum alloys have high strength. After a certain degree of cold working can strengthen the matrix strength, some trademarks of aluminum alloy can also be strengthened by heat treatment.
2. Stable processing
Aluminum alloy shell CNC processing is more stable, will not be like man-made processing deviation, resulting in each aluminum alloy is not the same, and even the emergence of defective products.
3. Complex aluminum parts can be produced
CNC machining of aluminum alloy shell can produce complex aluminum parts, and even machined parts. It can also produce a variety of varieties, with high production efficiency, saving labor costs, and can simultaneously realize a variety of multi-volume production.
