The model is used to determine melt flow index (grams /10 minutes), Melt Volume rate (cu.cm/10 minutes) and Melt Density (grams/cu.cm).MFI can be determined both methods A & B of ASTM D 1238 and ISO 1133 standards.Method A is a very simple and is focused on cutting the flowing extrudate with respect to time and recording the mass in order to .The MFi5 is a compact instrument that allows rapid inspection of the melt mass flow rate of plastics to Method A, Method B and Method C. It is especially designed for different needs, from simple Incoming Material Acceptance to Process Control checks. The manually operated MFi5 tests plastics quickly and reliably thanks to the pre-set methods. ASTM D1238 and ISO 1133 are the most common standards for melt flow tests and define the equipment specifications, as well as test methods. Because various temperatures and weights are allowed for melt flow tests (only suggestions for each material type), test parameters always need to be reported with MFR/MVR results.1.0 INTRODUCTION TO MELT FLOW INDEXING 1.1 MELT FLOW RATE The melt flow rate (MFR) of a thermoplastic material is the measured gravimetric flow of the sample extruded through a die following specified conditions of die length, diameter, temperature and pressure. Different standardised conditions of extrusion temperatures and pressures are used
