Class A defects: Users who have not been trained in stamping parts Ⅰ and Ⅱ can also notice this type of wave, but the user cannot accept them, and the stamping parts must be frozen immediately after discovery.

Type B defects: This type of wave is an unpleasant defect. The tangible and visible waves in the stamping parts I and II need to be repaired.
