How are various types of aluminum profiles made?
The production method of various types of aluminum profiles involves a number of key steps, mainly including melting casting, extrusion, surface treatment and other processes. The following is the detailed production process:
1. Melting casting: According to the specific grade of the required alloy, accurately calculate and match various alloy components, and then add these raw materials to the melting furnace to heat and melt. By means of refining such as degassing and slagging, the impurities and gases in the melt are effectively removed. Subsequently, the molten aluminum is cooled into various specifications of round casting rods by deep well casting system under specific casting process conditions.
2. Extrusion: According to the section design of the profile product, the corresponding mold is manufactured. The heated round cast rod is pushed through the mold under the action of the extruder to form the desired profile shape. This process requires strict control of extrusion speed and temperature to ensure profile uniformity and surface quality.
3. Surface treatment: In order to improve the corrosion resistance and beauty of aluminum profiles, surface treatment is usually required. Common surface treatment methods include anodizing, electrophoretic coating and spraying. These treatments not only enhance the durability of the aluminum profile, but also give it a rich color and texture.
Finally, the production of aluminum profiles is a complex and fine process that needs to be completed through multiple links.
