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)

To calculate the melt flow rate, multiply the total material extruded by 600, then divide by the total time of extrusion.

## How to Calculate Melt Flow Rate?

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

- First, determine the total weight of material extruded (g).
- Next, determine the total time of extrusion (seconds).
- Next, gather the formula from above = MFR = WE * 600/T.
- Finally, calculate the Melt Flow Rate.
- 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** **= ?
