      The reason for the damage of the aluminum plate is due to the adhesion of impurities on the surface of the ingot or the segregation of the ingot composition. There is a large amount of segregation and floating matter on the surface of the ingot, and the ingot is not homogenized or the effect of homogenization is not good, and the ingot exists. A certain amount of hard metal particles that adhere to the surface of the work belt or cause damage to the work belt when the metal flows through the work belt during the extrusion process, eventually causing scratches on the surface of the profile. There is debris in the mold cavity or working belt, and the hardness of the working belt of the mold is low, so that the surface of the working belt is injured during the extrusion and the profile is scratched;

      Some of the damage is caused by the artificially dragging the profile on the pendulum bed. When the fork bar sends the profile from the discharge rail to the swinging bed, the profile is scratched due to the excessive speed.

       There is also a bare metal or graphite strip in the discharge rail or pendulum bed with hard inclusions, which cause scratches on the surface of the profile when it comes into contact with the profile; friction or extrusion between the profiles during transportation damage.

       The solution for damage to the aluminum plate improves the quality of the mold, the mold is periodically nitrided and the nitriding process is strictly performed. Separate the profile from the accessory with a soft felt to minimize contact damage between the profile and the accessory. Strengthen the control of the quality of the ingot, and take it lightly in the production, try to avoid dragging or turning the profile at will.
