Causes of surface bruises on industrial aluminum profiles
2023-02-06
The surface of industrial aluminum profiles: reasons for scratches, scratches, scratches: 1. Impurities attached to the surface of the ingot 2. The composition of the ingot is segregated, and there are a large number of segregated floating objects on the surface 3. First, there are a certain amount of hard metal particles in the ingot when the ingot has not been homogenized or the homogenization effect is not good. When the metal flows through the working belt during the Extrusion Process, these segregated floating objects or hard metal particles adhere to the surface of the working belt or cause damage to the working belt, and finally cause scratches on the surface of the profile.
4. There are sundries on the mold cavity or the working belt, and the hardness of the mold working belt is low, so that the surface of the working belt is injured during extrusion and scratches the profile; 5. There are exposed metal or hard inclusions in the graphite strip on the discharge track or swing bed. Scratches the surface of the profile when it comes into contact with the profile; 6. When the fork rod sends the profile from the discharge track to the swing bed, the profile is bruised due to too fast speed; 7. Artificially dragging the profile on the swing bed to cause scratches; 8. During the transportation process, the profiles are rubbed or squeezed to cause damage.
