Aluminum Profile Die-casting are a common building material commonly used in the production of doors, windows, partitions, furniture, and other products. There are various manufacturing methods for aluminum profiles, including extrusion, casting, drawing, and welding.

Firstly, the extrusion method is currently the most widely used method for manufacturing aluminum profiles. After heating the aluminum material to a certain temperature, it is extruded into various shapes through the extrusion effect of the mold, and then cooled and solidified to obtain the desired aluminum profile.Next is the casting method, which involves pouring aluminum liquid into a mold, Aluminum profile die-casting cooling and solidifying it to obtain the desired aluminum profile. This method is suitable for some complex shaped aluminum profiles, but the manufacturing cost is relatively high.

The drawing method is to heat the aluminum billet and pull it into a slender aluminum profile through tension. This method can produce high-precision aluminum profiles, commonly used in the production of products such as wires and cables.

Finally, Aluminum profile die-casting the welding method involves cutting the aluminum billet into a certain length and then welding it into various shapes of aluminum profiles. This method is suitable for producing some special shaped aluminum profiles, but the welding process requires high requirements.

Overall, there are various manufacturing methods for aluminum profiles. Choosing the appropriate manufacturing method based on different needs and product characteristics can improve production efficiency and product quality. I hope the above content is helpful to you.

Aluminum profile processing process: Aluminum profile processing method:

The production of Aluminum Alloy Profiles includes three processes: casting, extrusion, and oxidation.

1. Melting and casting is the first process in aluminum production.

Main process:

(1) Ingredients: Calculate the amount of various alloy components to be added according to the specific alloy grade required for production, and reasonably match various raw materials.

(2) Melting: The prepared raw materials are added to the melting furnace according to the process requirements for melting, and impurities and gases in the melt are effectively removed through degassing and slag refining methods.

(3) Casting: The melted aluminum liquid is cooled and cast into various specifications of round cast rods through a deep well casting system under certain casting process conditions.

2. Squeezing: Squeezing is a method of forming profiles. First, design and manufacture a mold based on the cross-section of the profile product, and use an extruder to extrude the heated round cast rod from the mold into shape. The commonly used grade 6063 alloy undergoes an air cooling quenching process and subsequent artificial aging process during extrusion to achieve heat treatment strengthening. Different grades of heat treatable strengthening alloys have different heat treatment systems.

3. Oxidation: The surface corrosion resistance of extruded aluminum alloy profiles is not strong, and surface treatment through anodizing is necessary to increase the corrosion resistance, wear resistance, and aesthetic appearance of the aluminum material.

The main process is:

(1) Surface pretreatment: Clean the surface of the profile using chemical or physical methods to expose the pure substrate, in order to obtain a complete and dense artificial oxide film. Mirror or matte surfaces can also be obtained through mechanical means.

(2) Anodizing: Under certain process conditions, the surface of the substrate of the pre treated profile undergoes anodizing, forming a dense, porous, and strongly adsorptive AL203 film layer.

(3) Sealing pores: The pores of the porous oxide film generated after anodizing are sealed to enhance the anti pollution, corrosion resistance, and wear resistance of the oxide film. The oxide film is colorless and transparent. By utilizing the strong adsorption property of the oxide film before sealing, some metal salts can be adsorbed and deposited inside the film pores, which can make the surface of the profile appear in many colors other than its natural color (silver white), such as black, bronze, gold, and stainless steel.
