Aluminum machining process and quality control points
Dec 08, 2017

In general, the process of aluminum machining can be divided into four main stages, namely casting, extrusion, post-processing and surface treatment. Including casting aluminum as the first process of processing, which also includes three aspects, namely ingredients, smelting and casting.

 

In the ingredients link, mainly based on the actual processing needs, in advance to calculate the aluminum processing required for the addition of a variety of alloy components, and reasonable with a variety of raw materials. The next step is smelting, in fact, the good raw materials are added to the melting furnace according to the requirements of the process, and a certain method is adopted to remove the impurities and gases in the melt effectively. Finally, the molten aluminum is melted into a casting rod of different specifications through a deep well casting system under a certain casting process condition.

 

Then is the extrusion process, the process is actually part of the processing of aluminum forming means. The specific process is: 1, first according to profile section design mold; 2, to create a suitable mold; 3, the use of the extruder will be heated round casting rod from the mold extrusion. In addition, in the extrusion process, but also will use an air-cooled quenching process and artificial aging process, so mainly to make it after heat treatment performance has been strengthened.

 

Of course, want to further complete the aluminum processing all the processes, but also the need for further processing. In fact, this aspect is to make the aluminum product initially has the finished product or semi-finished product features, so this process has a very important significance.

 

When the completion of the above three processes, the last step of aluminum processing is surface treatment. The reason for the surface treatment is that it is possible to the corrosion resistance of a strengthened aluminum material while enhancing its abrasion resistance and the aesthetic appearance.
