The specific production process starts from the extrusion die and then goes to the extruder. After heating, the aluminum rod is extruded by an extrusion die to form a section of aluminum profile.
Aluminum profiles are generally post-processed. After aging, some CNC lathe processing, drilling, slotting and tapping are needed.
There are some surface treatments in the later stage, such as anodizing, electrophoresis, baking paint and so on.
