1. Dies may be out-of-match.
2. Dies may be overloaded. Reduce the Die Squeeze.
3. Look for tipping of the blanks at the Start End. If found, adjust Starter Finger air assist, or increase Hold-Down finger pressure.
4. Check to see if additional grinding of the Starter Finger is required to fit a Shoulder on the blanks.
5. If blanks are slipping at the Start End, decrease Start End Squeeze or look for worn dies that should be replaced. Consider using dies with Start End Corrugation.
6. If the dies have a deep Corrugation, consider using dies with shallow or no corrugation.
7. Make sure the Dies are correctly seated in the Die Pockets. If not, the helix angle can be effected causing flakes.
8. Be sure the machine and die set are not too large for the blank size.
9. Check the material hardness and brittleness of the blanks.
10. Make sure there are not seams on the blanks which are creating flakes.
