The quality inspection methods of electronic stamping parts are:

Quality inspectors wear gloves and touch the electronic stamping parts close to the surface vertically. If necessary, they can be used for polishing verification of detected suspicious areas, but this method is an effective and fast detection method.

Wipe the surface of the workpiece with a clean gauze, and then rub it with an oil stone. The whetstone uses fine-grained whetstone to grind the direction roughly in the length direction, and combined with a good stamping surface, some special places can also be added for lateral grinding.

The flexible gauze is polished, and the surface of the cover is wiped with a clean gauze. The surface of electronic stamping parts should be ground longitudinally with a flexible sand net, which can easily make any pits and indentations.

Oil inspection, clean the surface of the cover with a clean gauze. Then apply a clean brush evenly over the entire outside surface of the punch in one direction. After the stamping parts are tested under strong light, the stamping parts are erected on the body position. With this method, it is easy to find small pits as well as flat ripples on stamped parts.

The precision metal stamping factory has the above methods for inspecting stamping parts, and the pass rate of final product inspection is ≧99.7%.
