Two major processes in the processing of aluminum profiles
Jul 20, 2018

At present, in the processing of aluminum profiles, there are two key processes, namely casting and extrusion. Among them, the casting process is the first process of aluminum profile processing. In this process, the ingredients are first determined. Usually, according to the specific alloy grades that need to be produced, the amount of processing of various aluminum profiles is calculated, and various raw materials are reasonably matched.

 

The second is to carry out smelting, that is, in the processing of aluminum profiles, the raw materials that have been matched are added to the melting furnace according to the process requirements, and the impurities and gases in the melt are effectively removed by means of degassing and slag refining. The next step is to carry out the casting, that is, the molten aluminum liquid is cooled and cast into various specifications by a deep well casting system under a certain casting process condition.

 

Extrusion is an important method for forming profiles during the processing of aluminum profiles. Generally, it is necessary to design and manufacture a mold according to the cross-section of the profile product, and use the extruder to extrude the heated round cast rod from the mold. An air-cooling quenching process followed by an artificial aging process is also used during the extrusion to complete the heat treatment strengthening.
