In the entrance section, the raw aluminum coil is sent to the production line, which is smoothed by the flattener. This step ensures that the product has a good flatness, and the aluminum coil enters the storage rack, where there are two reels to ensure that one of them is always in standby state to maintain the continuity of the production line.
Then, the storage shelf is emptied, and the production line continues to operate, driving the subsequent procedures. During pretreatment, the aluminum coil is repeatedly cleaned by water spray, which can improve the corrosion resistance of the product. The protective film comes with general additional information, such as paint and aluminum coil details. These protective films have no impact on the environment and are easy to recycle.
