(Summary description)The surface star of the stamping parts refers to the tiny convex hulls that appear on the surface of the large cover parts in the stamping production. When the appearance quality of the stamping parts is checked with oilstone, the tiny bright spots on the surface can be seen. These tiny defects will cause messy and irregular reflection of light after painting and affect the appearance quality.

The surface star of the stamping parts refers to the tiny convex hulls that appear on the surface of the large cover parts in the stamping production. When the appearance quality of the stamping parts is checked with oilstone, the tiny bright spots on the surface can be seen. These tiny defects will cause messy and irregular reflection of light after painting and affect the appearance quality. What is the main reason for the surface stars produced by stamping parts? Follow the editor of CISCO Stamping Part to have a simple understanding!
1. The surface of the raw material is dirty due to not cleaned the surface of the material or the cleaning oil is not clean;
2. The surface of the raw material is dirty due to poor preservation of the material after cleaning or long-term storage after unwinding and blanking;
3. The mold is not cleaned or the mold is not cleaned in time, which causes the mold surface to be dirty;


4. The surface of the base metal is dirty before hot-dip galvanizing;
5. After the mold is produced for a long time, the chromium plating layer on the surface is destroyed, and the surface of the material is dezincified due to the friction between the mold and the material surface after drawing;
6. The dust-proof condition of the production workshop is not good, and the production site has dust falling on the surface of the material and the surface of the mold;
7. In the process of handling and production, when workers wear ordinary protective gloves, the lint produced by the friction between ordinary protective gloves and the sheet will fall into the surface of the material and the surface of the mold;
8. The cutting powder produced in the trimming and punching process enters the mold.
The above is an introduction to the reasons why the CISCO Stamping Part editor introduces the surface stars of stamping parts.
