Material deformation pits, damage by external forces, visible depressions after powder coating | |
Visible traces after powder coating | |
Defective notches generated by laser cutting | |
Squeeze marks generated by bending mold | |
Visible traces of rivet nuts after finish | |
Poor flatness of the board, poor straightness of the profile, and overall deformation caused by material defects or processing | |
Local deformation caused by impact during transportation | |
The marks formed by uneven polishing of the weld seams | |
not flat splicing seams with obvious gaps or cracks at the splicing welds | |
slot holes Increased according to actual needs when designing bending processes | |
Plastic powder block or impurities that protrude from the surface or clump in the coating | |
Multiple shrinkage pores with visible depth are generated in the coating | |
A big block wrinkled surface resembling orange peel on the coating | |
Much bubble protrusions appear on the surface due to poor spraying operation | |
coating peeling off due to poor spraying operation or collision | |
The partly powder layer is too thin, resulting in a uneven color block after finish and the visible surface of the substrate, usually in the corner or back side | |
The marks left by the hook shielding during powder coating | |
Due to excessive and uneven local spraying, there is a concentrated accumulation block after finish | |
Due to excessive local spraying, thick and concentrated coating blocks are produced in the corners | |
Due to incomplete cleaning of the production line, there are color spot defects that do not match the color of the product | |
Traces left on the surface of the product due to incomplete cleaning of oil stains | |
The difference color than sample or the color card | |
not smooth surface between the junction of two different colors | |
Pattern blurring, ghosting, breakage, tilting, deviation, poor adhesion, after screen printing | |
Welding slag splashed onto the surface of the plate but not removed | |
