Jwell casting film roller with strict European professional manufacturing standards, after multi-pass welding and heat treatment process, to ensure the overall structure of the roller solid and reliable. In order to ensure the high efficiency of heat exchange, the flow passage of the casting roller is designed in a special spiral shape, and the coolant flow through the passage is calculated accurately, thus reducing the temperature error of the roller and the surface of the roller as much as possible, the temperature uniformity of the product is improved. The precision of dynamic balance of roller for casting film is very important. The special large-scale dynamic balance checking equipment and various balance checking schemes make it run smoothly at high speed.
