Extrusion ratio calculation
Web2 days ago · This is normally used when performing a tubing extrusion where the cable is traveling faster than the extrudate exits the die. Hence, the melt is drawn down. The draw down ratio is the cross sectional area … Webof the process section is 800 mm then the L/D ratio is 800/20, or 40/1 L/D. A different mindset and methodology is required when attempting to minimize the material usage while effectively evaluating the extrusion process. To a degree, this is somewhat uncharted territory.
