      What methods can improve the quality of precision metal stamping parts?
      Release time:2022-08-05Views:1975


      Precision metal stamping parts are widely used in our daily life. Many industries use precision metal stamping parts because of its high precision and quality requirements. In order to make the application of precision metal stamping parts more extensive, we must improve the quality of precision metal stamping parts accordingly. So, what method can improve the quality of precision metal stamping parts? The details are as follows:

      1. Keep convex and concave mold surfaces clean. The blank of precision metal stamping parts shall be wiped clean before stretching, so as to prevent the stamping working surface or material surface from being mixed with sundries, thus compressing the surface of metal stamping parts and affecting the quality.

      2. 
      Properly adjust the clearance between convex and concave molds of precision metal stamping parts to avoid that the clearance is too small or uneven, which will scratch the workpiece surface during deep drawing.

      3. 
      Grind the concave mold fillet radius of precision metal stamping parts to avoid the rough concave mold fillet surface scratching the surface of precision stamping parts during deep drawing.

      4. Properly increase the hardness of the punch surface. Check the punch surface frequently during deep drawing. Even if the remaining metal scrap is removed, because when the punch hardness is low, the metal scrap adheres to its surface, which will cause the metal stamping parts to produce a pull mark.

      5. Use lubricant suitable for deep drawing process. If necessary, filter the lubricant before use to avoid impurity mixing. If the lubricant quality is poor, it will increase the surface roughness of precision metal stamping parts and reduce the stamping accuracy and quality.
