In the whole process of duct production. If you don't understand this, it's hard to understand the principle. It plays an important role in the whole air duct production line. So, how does it operate? Follow the duct production line manufacturers to understand it. Actually, spinning is mainly divided into two types, namely ordinary spinning and strong spinning. The main function of ordinary spinning is to change the structure of air duct blank.

For the duct, the wall thickness change is small. Ordinary spinning affects the quality of the whole air duct to a certain extent. Therefore, the wall thickness and length of the workpiece are changed, and the effect is much more obvious than ordinary spinning. In practical operation, we should pay attention to the strength of spinning.
