Precision metal stampingWidely used in our daily lives, many industries have high requirements for precision and quality of precision metal stamping. To make the application of precision metal stamping more widespread, it is necessary to improve its precision metal stamping to ensure the quality of precision metal stamping parts. So how to improve the quality of precision metal stamping parts?

1. In order to maintain the cleanliness of the concave convex mold on the surface, the deep part of the blank needs to be wiped clean before precision metal stamping to avoid impurities from entering the unclean punch surface or material surface, which may damage the surface of the precision metal stamping part and affect its quality.

2. Adjust the appropriate mold gap to avoid scratching the surface of the workpiece during the drawing process due to the mold gap being too small or uneven.

3. Polish the rounded corners of the mold to avoid rough surface, and scrape the surface of precision metal stamping parts during the drawing process.

4. Properly increase the hardness of the surfaces of the concave and convex molds, and regularly check the surfaces of the concave and convex molds in the drawings, even if the residual metal shavings are removed, because when the hardness of the concave and convex molds is low, the surface, together with the metal waste, will cause tensile marks on the drawings of precision metal stamping parts.

5. Use lubricants suitable for deep drawing processes. If necessary, filter the lubricant before use to avoid impurities. If the quality of the lubricant is poor, the surface roughness of the stretched precision metal stamping parts will increase, thereby reducing the accuracy and quality of precision metal stamping.
