Must-Read for Metal Stamping Manufacturers: Solutions to Stamping Issues

This article introduces measures taken by metal stamping manufacturers to address common stamping problems, aiming to achieve more stable production.

1. Product stability issues

When mold life is not the issue, check the locating structure to ensure the part does not shift inside the die or fixture, which can cause dimension instability or burrs.

2. Indentation and damage

Indentation issues include scrap indentation, feeding damage, mold marks, foreign object damage, and part-to-part damage. Operators should regularly clear chips and debris from the die, for example using a fixed air gun, and clean the blanking holes to remove waste.

3. Burrs

Burrs may result from poor die cutting edges. Improve by replacing punches or regrinding the cutting edge.

4. Scratches

(1) Grind the die surfaces to avoid collisions between parts;

(2) Evaluate packaging material to prevent scratches from handling;

(3) Handle parts carefully during transfer to avoid scratches.

5. Die marks

Die marks or impressions can be caused by poor die quality or part structure. Repair dies or modify part structure to improve.

6. Cracking

Cracking can arise from poor material stretchability or excessive mold pressure.

7. Deformation

Deformation may result from poor die forming or damage during transport. Repair dies promptly when deformation is found. For transport induced deformation, improve packing and handling procedures.
