Plastic Extrusion

This calculator estimates the typical output for plastic screw extrusion processes. The calculation is based on standard extruder screw geometry and typical output rates.

First select the polymer. Enter or modify the other requested values and press calculate.

No compensation is given for high discharge pressures, high viscosity or screw wear.

Select Polymer
Barrel Diameter:	in	MM Diameter:
Current Screw RPMs:	RPMs	Typical Max RPMs:
Screw L:D to first vent or die:	L:D	(16-26 Typical Range)
Melt Density	Gram/cm³	(See chart, Typical=1)
Tuning Factor	Lbs/hr	(See chart, Typical=1)

Typical Output Rate:	Lbs/hr		KG/hr
Potential problems if below:	Lbs/hr		KG/hr
