How do stamping manufacturers check the quality of metal stamping parts
In daily production, stamping manufacturers must check the quality of metal stamping parts to ensure that good products are delivered to customers and win trust. In metal processing, raw materials should be controlled first, cleaning, inspection before stamping and final inspection after production.
The detailed steps for stamping manufacturer to inspect metal stamping parts are as follows:
The inspection personnel wear gloves and contact the stamping parts vertically close to the surface. If necessary, it can be used for polishing verification of the detected suspicious areas. However, this method is an effective and rapid detection method.
Clean the surface of the workpiece with clean gauze, and then wipe it with oilstone. Whetstone with fine-grained whetstone grinding direction, approximate length direction, combined with good stamping surface, some can also add special place for lateral grinding.
Polish the flexible gauze and wipe the surface of the cover with clean gauze. The surface of the workpiece shall be longitudinally ground with flexible sand mesh, and any pit and indentation can be easily found.
Oil inspection, clean the surface of the cover with clean gauze. Then apply a clean brush evenly to the outer surface of the press in the same direction. After the oil stamping parts are tested in strong light, the stamping parts are erected in the body position. With this method, it is easy to find small pockmarks, flat ponds and ripples on stamping parts.
