How To Choose Precision Stamping Parts

Precision stamping parts are widely used in people's daily life, but most people are not very clear about the purchase of precision stamping parts.
1. Touch detection: Wipe the surface of the outer precision stamping parts clean with a clean gauze. The inspector should wear rubber gloves and touch the stamping part vertically against the surface of the stamping part. This detection method depends on the experience of the inspector. If necessary, the explored anomalous area can be polished with oilstone and verified in many ways, but this method is nothing more than a practical and rapid detection method.
2. Whetstone grinding and polishing:
1. Wipe the surface of precision stamping parts clean with a clean gauze, and then use oil stone (20×20×100 mm or larger) for polishing, and use relatively small parts for curved places and inaccessible places Whetstone grinding and polishing
2. The selection of oil stone particle size distribution depends on the surface conditions (such as surface roughness, hot-dip galvanizing, etc.). It is recommended to use a coarse-grained oilstone. Most of the grinding and polishing directions of the oilstone are carried out vertically, and it fits the surface of precision stamping parts very well, and some areas can also supplement the horizontal grinding and polishing.
3. Grinding and polishing of soft diamond yarn, wipe the surface of precision stamping parts with clean gauze. Use a soft sand net close to the surface of the precision stamping part to polish and polish the entire surface vertically, and any spots and embossing will be easily found.
4. For oil inspection, wipe the surface of the precision stamping parts clean with a clean gauze. Then use a clean soft brush to evenly apply oil to the entire surface of the stamping along the same direction. Put the stamped parts coated with oil under strong light for inspection, and it is recommended to erect the stamped parts on the body part. With this method, it is very easy to find tiny black spots, puddles, and waves on the stamping parts.
5. Visual inspection: Visual inspection is mainly used to detect abnormal appearance and macroeconomic defects of precision stamping parts.
6. Tooling fixture inspection: Put the stamping parts into the tooling fixture, and inspect the stamping parts according to the operating instructions of the tooling fixture.
