Aluminum foil thickness control

Aluminum foil thickness is difficult to control.

Because the thickness of aluminum foil is very thin, other trace conditions will have an impact, such as temperature, oil film, and oil and gas concentration.

A rolled roll of aluminum foil can reach hundreds of thousands of meters, and the rolling time is as long as about 10 hours. As time goes by, thickness measurement errors are easy to form, and the means of adjusting the thickness are only tension and speed. These factors make it difficult to control the thickness of the rolled aluminum foil.
