There are several ways to correct the 90-degree bending angle of hardware mould.
There are only two situations where the angle can't be reached, one is too big, and the other is too small. Whether it is too big or too small, it is caused by the rebound when the material is still in the elastic deformation stage during the bending process. Here are two simple suggestions for you. First, the parting line of flanging and bending should be set within the R angle, and the flanging die should include R; Second, adjust the stamping process and change the stamping angle, which generally does not exceed 10 degrees. This method can compensate the springback change well, and both positive springback and negative springback are well controlled. Generally speaking, the second method is very useful.
