Melt Flow Index – Win Series

Model No. : MFI – Win

Melt Flow index is considered as the most important property of the granulated plastic. Knowing the value of MFI helps in deciding its application or to check its suitability according to the application. Presto’s MFI – Win Series is the perfect machine to achieve highly accurate and reliable test results. In this test, the granulated plastic is charged in the hot barrel. A pressure is applied via piston using variable dead weights. The rate at which molten plastic flows in 10 minutes is defined as the Melt flow index. The machine has a standardised orifice, also called die, with predefined dimension. The dimensions of the orifice are very important as it is standardised by the relative testing authorities.

The machine is accompanied by many accessories and every accessory is very important. It comes with a plumb line, which determines the levelling of the machine. In the case of inaccurate levelling, the test results may vary or the flow of molten plastic is not appropriate. Similarly, the orifice cleaner is very important as it helps in wiping out remains of previous test samples. Otherwise, this would interfere with the fresh granules. This mixing of granules leads to inappropriate test results. The devices are designed for high precision and repeatability.

The device is manufactured under test standards ASTM D 1238-1992, IS 2267-1972, IS 2530-1963, IS 10810-1984.
