How does the auto stamping parts factory inspect the metal stamping parts?

In the processing and production process of metal stamping parts, some product quality problems will inevitably occur. In order to ensure that customers receive products with good quality and meet their needs, the inspection of metal stamping parts is an indispensable part of the production process. So, how do auto stamping parts factories inspect metal stamping parts? 1. Touch inspection Wipe the surface of the outer cover with a clean gauze. The inspector needs 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 inspector's experience. Whetstone can be used to polish the detected suspicious area and verify it, but this method can be regarded as an effective quick inspection method. 2. Polishing of the flexible gauze Wipe the surface of the outer cover with a clean gauze. Use a flexible gauze close to the surface of the metal stamping part to be polished to the entire surface in the longitudinal direction, and any pitting or indentation will be easily found. 3. Oiling inspection Wipe clean the surface of the outer cover with a 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 metal 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. 4. Visual inspection Visual inspection is mainly used to find abnormal appearance and macro defects of stamping parts. 5. Whetstone polishing (1) First, wipe the surface of the outer cover with a clean gauze, and then polish it with a whetstone. Use a relatively small whetstone for arcs and hard-to-reach places. (2) The choice of whetstone particle size depends on the surface condition (such as roughness, galvanizing, etc.). It is recommended to use fine-grained oilstone. The direction of whetstone grinding is basically along the longitudinal direction, and it fits well on the surface of the stamping parts. Some special places can also be supplemented with horizontal grinding. 6. Inspection tool inspection Put the stamping parts into the inspection tool, and inspect the metal stamping parts according to the operating requirements of the inspection tool manual. Precision, focusing on precision metal stamping, metal insert injection molding, independent research and development of visual inspection equipment, to escort the reliability of each product.
