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.
