Extrusion is the plastic deformation process that in this process aluminium billet is get under pressure to cross among the special die and give a profile that the surface is fixed among the length of the profile.
The produced billet from casting unit prepare for each extrusion machine. After profucing the hot profile they are cut and ready for the stetching process.
The profile is stretched for homogenization the surface of the profile becouase of being Mg2Si and also fixing the surfaces. After the strechting the size of the profile should be increased about 1.5 to 3 percent of the original size.
The profile is cut as the ordered size and get ready to go to aging process for hardening the profiles. The temperature and time are the important part of the aging process.
