Qualified industrial aluminum profiles should have a smooth and beautiful surface. However, with the increasing demand for industrial aluminum profiles from enterprises nowadays, many aluminum profile manufacturers with uneven technical levels continue to emerge. Many industrial aluminum profile processing manufacturers have been producing aluminum profiles with sassafras, scratches, and bumps due to their strength and insufficient production and management. What are the reasons for the surface damage of industrial aluminum profiles?
       
       1. There are impurities or segregation of ingot components on the surface of the ingot. There are a certain amount of hard metal particles in the ingot. When the metal flows through the working belt during the extrusion process, these segregation floats or hard metal particles adhere to the surface of the working belt or cause damage to the working belt, and cause damage to the surface of the profile. Scratches;

  2, when the fork rod sends the profile from the discharge rail to the swing bed, the profile will collide due to the excessive speed;

  3. There is debris on the mold cavity or the 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 extrusion and scratches the profile;

  4, artificially dragging industrial aluminum profiles on the swing bed to cause scratches;

   5. There are bare metal or graphite strips on the discharge track or swing bed with hard inclusions, which will scratch the surface of the industrial aluminum profile when it comes in contact with the profile;

  6. The friction or extrusion between the profiles during transportation causes damage.
