How to judge the quality of stamping parts?

When using a product, we tend to pay more attention to the quality of the product, so for stamping parts, how do we judge whether its quality meets the standards and requirements? First, we can check its performance and quality by touching it by hand. The specific steps are: first find a piece of clean gauze and wipe off the dirt on the outside of the stamping parts. Then wear special gloves to touch the surface of the workpiece along the longitudinal direction. This method usually requires experienced inspectors to carry out. Second, use the method of sanding with oilstone to judge. The steps to be taken are: Same as above, first wipe the surface of the product with a clean gauze. Then polish with whetstone, and choose appropriate whetstone for different parts. It is worth noting that the choice of the whetstone particle size should be carried out according to the surface conditions. However, it is better to use fine-grained oilstone. When sanding, just follow the longitudinal direction and fit the surface of the stamping part. Third, use flexible gauze polishing method to judge. The first step is to clean up the dirt on the surface of the product. Next, use a flexible sand net to stick to the surface of the stamping part and grind it to the entire surface in the longitudinal direction. At this time, you can easily find some pitting or indentation. . The fourth method is oil inspection. Same as above, the first step is to remove the dirt on the surface of the product, and then the staff will hold a clean brush and slowly apply grease in a certain direction until the entire outer surface of the stamping part. Then observe under strong light, you can find whether there are pitting and ripples. In addition, the two methods that can be used are visual judgment and gage inspection. The former is usually used to observe whether there are any abnormalities and defects in the appearance of stamping parts. The latter is to put the stamping parts into the inspection tool, and then inspect them according to the relevant steps, so as to find out whether there are quality problems.
