Enter the total weight of material extruded (g) and the total time of extrusion (seconds) into the Melt Flow Rate Calculator. The calculator will evaluate the Melt Flow Rate. 

Melt Flow Rate Formula

The following two example problems outline the steps and information needed to calculate the Melt Flow Rate.

MFR = WE * 600/T

Variables:

  • MFR is the Melt Flow Rate (g/10-min)
  • WE is the total weight of material extruded (g) 
  • T is the total time of extrusion (seconds) 

How to Calculate Melt Flow Rate?

The following steps outline how to calculate the Melt Flow Rate.


  1. First, determine the total weight of material extruded (g). 
  2. Next, determine the total time of extrusion (seconds). 
  3. Next, gather the formula from above = MFR = WE * 600/T.
  4. Finally, calculate the Melt Flow Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total weight of material extruded (g) = 30

total time of extrusion (seconds) = 15

MFR = WE * 600/T = ?
