Part 2 Medical Tubing: Use Simulation to Troubleshoot, Optimize Processing & Dies
Simulation can determine whether a die has regions of low shear rate and shear stress on the metal surface where the polymer would ultimately degrade, and can help processors design dies better suited for their projects.
