Deep Stramping Aluminum Foil manufacturers tell you that making aluminum foil is similar to making pasta at home. A large block of almost pure aluminum is rolled several times through giant steel rolls, reducing the thickness of the block and spreading it out to make it longer. Lubricants are added during rolling for ease of operation. With each successive pass through the roll, the thickness is continuously reduced. The Deep Stramping Aluminum Foil manufacturer tells you to repeat the process until you reach the thickness of the foil, then cut the large aluminum foil to the desired width.

This may seem simple, but the actual process may not be easy. For example, when aluminum is pushed out, it heats up. The Deep Stramping Aluminum Foil manufacturers tell you that if it gets too hot, it will stick to the roll, so the pressure on the roll must be carefully controlled.
When the thickness of the aluminum plate is 5mm, it must be rolled again in the cold rolling stage. First, the sheet is coiled on a roll and sent to a cold rolling mill for final rolling. It is at this point that the light and dark sides of aluminium are created. Since aluminum is so thin today, the tension required to convey the aluminum through the chill rolls can easily break the aluminum. Deep Stramping Aluminum Foil manufacturers tell you that because the aluminum sheet has two sides, the aluminum side in contact with the steel roll becomes smoother and glossier, and the aluminum side in contact with itself becomes matte.
