Surface quality of aluminum coil and aluminum sheet during cutting

It mainly refers to the fact that due to the depressions and protrusions on the roller surface, foreign matter adheres to the roller surface, causing marks, abrasions, scratches and oil stains on the surface of the aluminum sheet and aluminum coil.

Due to improper material selection and production process of the tension pad, scratches, oil stains and aluminum powder accumulation occur on the surface of the aluminum.

Due to improper tension between the uncoiler and the coiler, friction and scratches occur between the aluminum coil layers.
