Test Principle of Melt flow indexer test:  

The melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) are determined by extruding molten material from the cylinder of a plastometer through a die of specified length and diameter under preset conditions of temperature and load.

Feature of UnitedTest MFI404:

• Large Screen Touching screen;

• Both MFR/MVR test method;

• Motorized cutting and Manual cutting both way;

• With micro-printer;

• Show the temperature VS Time graph.

Test Procedure:

Approximately 7 grams of the material is loaded into the barrel of the melt flow apparatus, which has been heated to a temperature specified for the material. A weight specified for the material is applied to a plunger and the molten material is forced through the die. A timed extrudate is collected and weighed. Melt flow rate values are calculated in g/10 min. 

Specimen size:
At least 14 grams of material;

Data:
Flow rate = ( 600/t x weight of extrudate ) 
t = time of extrudate in seconds
melt flow rate = g/10 min.
