?? general, there are many factors that affect rebound. Due to the impact of rebound, the bent edge cannot be tight attached to the working part of the mold, but the corner is stretched out, resulting in a slight increase in the bending point. Therefore, the bending point of the sheet metal on the mold will not be the same as the working point of the mold, but slightly larger than the working point of the mold.
