The preparation process of aluminum foil rolls generally includes the following steps:
Prepare raw materials: Use aluminum ingots with higher purity to prepare aluminum foil strips through heating, rolling, extrusion and other processes.
Rolling: The aluminum foil strip is rolled repeatedly through a multi-pass rolling mill to change its hardness and softness to obtain the required aluminum foil roll.
Cutting: Use a high-speed cutting machine to cut the aluminum foil roll to the required length and width.
Coiling: Use a coiling machine to roll the aluminum foil into a roll.
Inspection and packaging: The thickness, hardness, etc. of the aluminum foil rolls are tested, and they are packaged after passing the test.
