There are roller marks on the surface of the aluminum foil

Roll marks, roll eyes and uneven gloss on aluminum foil are mainly due to aluminum foil defects caused by rolls.

Roll printing on the surface of aluminum foil is divided into three types: point, line and surface.

The most striking feature is that it occurs periodically.

The main reasons for this defect are:

incorrect grinding,

Foreign objects damage the roll,

The incoming material is defective and the roller is damaged.

roll fatigue,

Roller impact, slippage, etc.

All factors that can cause damage to the roller surface will harm the rolling of aluminum foil, because the surface of the aluminum foil rolling roller is very smooth, and slight uneven gloss will also affect the surface condition.

Regularly cleaning the rolling mill, keeping the rolling mill clean, ensuring the normal operation of the roller cleaner, and regularly changing the rollers are all basic conditions to ensure that the surface of the aluminum foil is uniform after rolling.
