1, track bending position is not accurate. If there is a deviation in the position of the bent rail, there will be problems in the size and flatness of the rolled aluminum foil, so it is necessary to locate the bent rail accurately.
2. The radius of curvature of the curved track is too large or too small. If the radius of curvature of the curved rail is too large, it will cause the aluminum foil to appear wavy after rolling; If the radius of curvature is too small, aluminum foil will be deformed and wrinkled.
3. The material and hardness of the curved rail do not meet the requirements. The material and hardness of the bent rail need to match the rolled aluminum foil material, otherwise the forming effect of the aluminum foil will be affected.
