  • Dimensional accuracy using servo press technology ​
  • Combined with very accurate, extremely small clearance die design

Results​

  • Extremely attractive tooling and piece part pricing​
  • Comparable to fine blanking dimensional accuracy and edge quality​
  • Complex part geometry with both conventional and fine blanked edges possible​
  • 80%+ burnished edge eliminating shaving or machining operations​
  • Very high dimensional accuracy and flatness achieved​
  • Holes smaller than the material thickness can be pierced​
  • Secondary operations like in-die tapping can be done in the press​
