It’s a quality issue on the part of the equipment manufacturer; installation is possible, but I won’t sign for it if it’s not fixed.
This is of the Xiuzhen type, right? It seems to be traces from flanging cutting; an ultrasound check is needed. If it’s only on the surface, it can be used after repair, but if it’s deeper, it will need to be treated.
The depression at point a is a defect resulting from external forces acting on the surface, while the fine line at point b may be a defect inherent to the flange itself. It is recommended to perform flaw detection on area B, and only restoration is needed for area A.
