Melt Flow Index Tester

Presto’s Melt Flow Index is designed exclusively for the perfect measurement of melt flow rate of molten plastics or granules. The Plastic melt flow index is calculated by performing a manual/ automatic test procedure on a testing instrument in order to check the melt volume rate of the flow of plastic granules (which is measured in grams in a precise time of ten minutes). The procedure passed through a jet having a particular measurement in diameter and length. It is carried out under a specific pressure and temperature with the ideal position of a piston in a cylindrical container inside a heated metallic barrel.

Presto is a leading manufacturer and supplier of melt flow index tester, melt flow resistance (MFR) Tester, Polymer testing machine, plastic granules testing instruments etc. all over the world for the purpose of flow rate testing. The testing equipment meets ISO and ASTM standards with the main focus on meeting the principal circumstances of load and temperature.

Presto offers two models of Melt Flow Index – MFI Deluxe Model and MFI NXG Model.
