MELT FLOW INDEX TESTER 3 2 FEET AND HEELS INTRODUCTION ACCURACY 1 CONCLUSION APPLICATIONS When a melt flow index (MFI) test is conducted using a particular kind of die known as a "feet and heels" die, the shape. A tool used to gauge the flow rate of melted thermoplastic materials is called a melt flow index (MFI) tester. While conducting melt flow index (MFI) tests on thermoplastic materials, the accuracy of the MFI tester must be taken into account. In conclusion, a common tool in the plastics sector for determining the flow characteristics. Manufacturers can choose the best thermoplastic materials for certain applications with the aid of MFI testing. 5 4

A tool called a melt flow index tester is used to gauge a molten polymer's flow rate under particular circumstances. The test gauges the volume of polymer that passes through a predetermined orifice in a predetermined amount of time at a predetermined temperature and pressure. In order to measure the melt flow index, a heated barrel, a piston, and a die with a predetermined orifice size are used. After being loaded into the barrel, the polymer sample is heated to a predetermined temperature. The molten polymer is continuously loaded by the piston and pushed through the die opening.
