Melt Flow Index MFI is the best and highly effective testing machine which is used in ascertaining various properties of plastics such as viscosity, chemical behavior, molecular structure, etc. The manufacturers in blow molding industries especially rely on calculating the melt flow index of the plastic granules to determine the quality of the plastics. By determining the MFI, the defects such as short shot, silver streak can be detected easily. The MFI tester accurately tests the plastics with great accuracy. Presto Stantest, a foremost manufacturer of Melt Flow Index MFI Tester, provides best options to determine the quality and various other properties of plastics.
