CALCULATOR FOR TIP AND DIE
This calculator allows you first to calculate a theoretical diameter for the tip and die based on factors DDR ("Draw Down Ratio") and DRB ("Draw Ratio Balance") on the left column.
Then, from these values and your actual disposable tooling, you can deduct the DDR and the DRB you will practically use (right column).
Values DDR and DRB depend on the type of polymer. A series of values collected from the literature is available on the right of this section.
