        Introduction of stamping parts inspection method:

        1 touch inspection

        Wipe the surface of the outer panel with clean gauze. The inspector needs to wear touch gloves to touch the surface  along the longitudinal direction of the stamping part. This inspection method depends on the inspector's experience. Whetstone can be used to polish the detected suspicious area and verify it, but this method is a viable quick inspection method.

        2 Whetstone polishing

        1) First, wipe the surface of the outer panel with a clean gauze, and then polish with oilstone (20×20×100mm or larger), and polish with relatively small oilstone for arc and hard-to-reach places ( For example: 8×100mm semi-circular oilstone)

        2) The choice of oilstone particle size depends on the surface condition (such as roughness, galvanizing, etc.). It is recommended to use fine-grained oilstone. The direction of whetstone polishing is basically along the longitudinal direction, and it fits well on the surface of the stamping parts, and some special places can also be supplemented with horizontal polishing.

        3 Polishing of flexible gauze

        Wipe the surface of the outer panel with clean gauze. Wipe the surface of the outer cover with clean gauze. If the flexible gauze is used to close to the surface of the stamping part and grind along the longitudinal direction to the whole surface, any pitting and indentation will be easily found.

        4 Oil inspection

        Wipe the surface of the outer panel with clean gauze. Then use a clean brush to apply oil evenly to the entire outer surface of the stamping in the same direction. Put the oiled stamping parts under strong light for inspection. It is recommended that the stamping parts be erected on the car body. This method can easily find tiny pits, pits, and ripples on the stamping parts.

        5. Visual inspection

        Visual inspection is mainly used to find abnormal appearance and macro defects of stamping parts.
