PNT’s Electrode Roll Press is machinery that rolls the coated web to a certain thickness.
The most important thing in rolling is to precisely control the gap between the main rolls so that a constant lip pressure is applied to the entire electrode.
PNT uses a hydraulic servo control system to control the position of the lower roll, so this ensures reproducibility within 1μm.
When rolling the anode electrode, hot rolling can be applied to achieve a higher pressure rate, and in the case of the cathode electrode, multi-stage rolling can prevent spring-back.
In addition, PNT has various wrinkle removal technologies, such as high frequency induction heating device, 1000N high tension stretching device, and so on.
