The virtue of our Main Former is stable and the distance of each roller is our valuable experience, this is our exclusive technology. If the roller distance too close or too far, when machine commissioning it will be difficult and if too close, the incremental forming will be faster and it is not good for the end product. So the current Forming line is just good and actually even we shorten the distance of the roller, it can not save much space, at most 1-2meters. Considering the T bar quality, the current distance is just good to make gradual incremental forming.
