What to do if the surface is scratched in the bending of precision metal stamping production-hardware

As we mentioned earlier, the precision metal stamping die is hard cut and hard cold stamped. When the stamping parts required by the customer need to be bent, the metal material needs to be cut in the stamping cavity, and then bent to form. Also due to the friction between the insert and the punch against the raw material, the stamped parts will be scratched after bending. How can this situation be controlled? (1) The surface of the raw material is not smooth, clean, and plain material; (2) There is waste in the molded block, remove the waste between the blocks; (3) The molded block is not smooth, the molded block is electroplated and polished to improve the convex and concave mold Smoothness; (4) The convex mold bending radius R is too small, increase the convex mold bending radius; (5) The mold bending gap is too small, adjust the upper and lower mold bending coordination gap; (6) The concave mold forming block is equipped with a roller to form.
