Conventional stamping does not know any material clamping action.
A conventionally stamped part shows the following Attributes:
Only approx. 30% of the cut surfaces are clean and free of tear-in and tear-off. The rest is broken.
The part does not remain even because the process lacks a counter force.
The stroke rate can be as much as 1000 strokes/min. because the part can fall through the die plate.
Conventional blanks usually need secondary operations (i.e. milling, grinding) in order to become ready for assembly.
