Preventing Cracks or Fractures in Stamped Drawn Parts

When stamped drawn parts show cracks or fractures during production, manufacturers should first analyze the causes and then take preventive measures to avoid recurrence.

1. Select appropriate sheet material during the design and development stage to meet deep-drawing performance requirements.

2. Inspect the surface quality of sheets during stamping production and remove surface rust and contaminants.

3. Regularly inspect and maintain dies, and polish die surfaces to achieve an appropriate surface roughness.

4. Standardize operations during production and strictly follow lubrication and oiling procedures.

5. Regularly inspect and maintain stamping equipment to ensure stamping accuracy.
