What are the reasons for the unevenness of the surface of the product when the number of pieces of the continuous die is one or more, and what measures should be taken?

1) Punching flashes, and studying the material level knife edge;

2) There are pressure injuries on the stamped parts, chippings in the mold, cleaning the mold, and solving the problem of debris floating;

3) The pressure of the convex die (bending position) is damaged or damaged, and the new part is renewed or replaced;

4) Turn over the material during punching and cutting, study the punching edge, adjust or add the strong pressure function;

5) Wear pressure loss, inspection, maintenance or replacement at the relevant pressure area;

6) The tearing of the relevant tearing position is inconsistent in size, wear of the blade, repair or replacement to ensure consistent tearing;

7) The relevant pre-cutting depth is not consistent, and the male and female molds are worn or chipped. Inspect the condition of the pre-cut male and female molds and perform maintenance or replacement.

8) There is chipping or wear on the convex and concave dies in the relevant convex areas. Check the condition of convex and concave molds, and perform maintenance or replacement.

9) Defective mold design, modification of design, addition of height adjustment or additional shaping station.
