Melt Flow Index calculation of plastic is one of the widely used test methods which are used in plastic manufacturing industries to control the quality of the incoming material. This calculation can be done perfectly with the help of MFI tester. Presto designs and manufactures high-quality of MFI tester which is used for Melt Flow Index calculation. It is the highly reliable and precise testing machine which is used to calculate the properties of the molten plastic granules. The result of the MFI test is expressed in grams per 10 minutes. The instrument is designed on the basis of various standards that are introduced by ASTM and ISO. Presto Stantest introduces two models of MFI tester:
The melt flow index calculation is an indirect method which is used to calculate the molecular weight of the polymer and ratio of high MFR to low molecular weight of the polymers. The MFR is the measurement of the ability of the material that flow when placed under pressure. Melt Flow Rate is opposite proportional to the thickness of the molten plastics which is judged by the test. Hence, the viscosity of the material is judged with the applied force.
Presto’s MFI tester is the best testing machine which is used to measure the flow rate of the polymers. The instrument is equipped with the digital PID temperature controller. It also offers the easy changeability of the weights and auto cutting facility of the sample. The device is considered as the best product worldwide as it accurately measures the precise melt flow rate of the plastic resins.
