How does a stamping factory solve the problem of material distortion in stamping production-hardware

During production in the stamping processing plant, a large number of holes are punched in the material, resulting in poor flatness of the material. The cause may be the accumulation of stamping stress. When a hole is punched, the material around the hole is stretched downwards, which increases the tensile stress on the upper surface of the plate, and the downward punching movement also causes the compressive stress on the lower surface of the plate to increase. For punching a small number of holes, the result is not obvious, but as the number of punching holes increases, the tensile and compressive stresses also increase exponentially until the material is deformed. One of the ways to eliminate this deformation is to punch every other hole, and then return to punch the remaining holes. Although this produces the same stress on the plate, it disintegrates the accumulation of tensile stress/compressive stress due to continuous punching one after another in the same direction. In this way, the first batch of holes share the deformation effect of the second batch of holes.
