Due to its easy functionality, an operator with basic working knowledge can operate it.


MFI - Win








Presto’s Melt Flow Index – Win Series is designed perfectly to measure the flow of granulated plastic. To test the flow rate of the plastic, the granules are charged in the heated metallic barrel. A specified load is applied on the granules using a piston and dead weight while pushing the molten granules to come out of the orifice. The melt flow is defined as weight of molten granules in 10 minutes. The dimensions of the orifice are predefined in the testing standards for relative industries. It is equipped with an in-built preset timer that assures high repeatability and accuracy of test results. Provided with a mirror, the operator can trace the sample coming out of the orifice for high precision. The device is manufactured under test standards ASTM D 1238-1992, IS 2267-1972, IS 2530-1963, IS 10810-1984.

To attain the precision in the measurement, the device comes with a plumb line, that assures that there is perfect levelling of the device.
