1. Touch inspection.
Wipe the surface of the outer cover with clean gauze. Inspectors need to wear touch gloves to touch the surface of the stamping part along the longitudinal direction of the stamping part. This inspection method depends on the inspectors' experience. [url=https://www.nbstarlite.com/product/]Automobile Press Parts[/url] indicate that if necessary, the suspected areas can be polished with oilstone and verified, but this method is an effective and fast inspection method.
1. Oiling inspection.
Wipe the surface of the outer cover with clean gauze. Then use a clean brush to evenly oil the entire outer surface of the stamping part along the same direction. Put the oiled stamping parts under strong light for inspection. It is recommended to erect the stamping parts on the vehicle body. With this method, it is easy to find tiny pockmarks, dents and ripples on stamping parts.
1. Grinding of flexible gauze.
Wipe the surface of the outer cover with clean gauze. With a flexible sand net attached to the surface of the stamping part, polish it to the whole surface along the longitudinal direction. Any pitting and indentation can be easily found.
1. Oil stone polishing.
(1) firstly, wipe the surface of the outer cover with clean gauze, then polish with oilstone (20×20×100mm or more), and polish with relatively small oilstone (e.g. 8×100mm semi-circular oilstone) for places with circular arcs and places difficult to reach (2) The particle size of oilstone depends on the surface conditions (such as roughness, galvanization, etc.). Fine-grained oilstone is recommended for automobile stamping parts. The polishing direction of the oilstone is basically along the longitudinal direction, and it fits well with the surface of the stamping part, and some special places can be supplemented with horizontal polishing.
1. Visual inspection.
Visual inspection is mainly used to find the appearance abnormalities and macro defects of stamping parts.
