In precision medical catheter production, selecting tooling dimensions is about controlling molecular memory. If the Draw Down Ratio (DDR) is too high, polymer chains stretch excessively, weakening the wall integrity. Conversely, if your Draw Balance Ratio (DRB) deviates from 1.0000, the inner and outer surfaces cool unevenly, introducing shear stresses that cause structural ovality, banana-ing, or kinking under torque load.
To ensure transparent process validation, our calculator computes parameters using standard volumetric mass calculations. The calculations determine required cross-sectional tool boundaries:
