Metal stamping

Met betrekking tot het onderhoud van metalen stempels:

1. Keep the surface of the convex and concave die clean. The blank of the precision stamping part needs to be wiped clean before deep drawing to avoid that the work surface of the die or the surface of the material is not clean and mixed with debris, which damages the surface of the precision stamping part and affects the quality.

2. Adjust the appropriate clearance of the convex and concave dies to avoid the surface of the workpiece being scratched when the drawing is too small or uneven.

3. Grind the corner radius of the die to avoid rough round corner surface of the die. The surface is scratched.

4. Appropriately increase the hardness of the surface of the male and female molds and check the surface of the male and female molds regularly when drawing. Even if the metal scraps are left behind, when the metal and metal wastes are attached to the surface, the drawing will be deepened Pull marks on precision stampings.

5. Use lubricants suitable for the deep-drawing process. If necessary, filter the lubricant before use to avoid impurities from entering. If the quality of the lubricant is poor, the surface roughness of the drawn precision stamping parts will increase, reducing the precision and quality of the stamping.

Common bad phenomena in stamping:

1. Jumping waste: refers to jumping out of the cavity of the concave mold during the stamping process, causing defects such as embossing.


  • Add ejector in the punch
  • Add secondary air hole in the punch
  • Taper the end face of the punch
  • Use a die insert as an air blowing device

2. Burr: sharp ridges on the cross-section of the product after stamping, generally improve the production process, and improve the stamping conditions can reduce the burr.


  • Grind the knife-edge
  • Control the machining accuracy and change the design clearance
  • The new punch and concave insert

3. Wrinkling and cracking: It is common in sharp corners of stretched parts and molded parts.



  • Polishing
  • Increasing R angle
  • Increasing ribs
