Product Overview: Melt Flow Index Tester for Polymer Flow Rate & Viscosity Testing

The Melt Flow Index Tester is a precision instrument engineered for measuring the melt flow rate (MFR) and melt volume flow rate (MVR) of thermoplastic polymers. It delivers reliable, repeatable data on material viscosity and processability, making it an essential tool for plastic production, quality control, and polymer research.
The instrument operates by melting plastic specimens inside a heated barrel. The molten material is loaded via a quantitative molding approach, and a built-in piston applies pressure to force the melt through a standard orifice die. Operators record either the mass of the extruded melt or the extrusion time, depending on the selected die and defined test parameters. The recorded data enables precise calculation of melt flow rate and flow index, which are used to assess the flow performance of polymer materials.

Applications Across Industries

This melt flow rate meter is widely deployed across plastic manufacturing, plastic finished goods production, and the petrochemical sector. It is also extensively used in universities, research institutes, and third-party inspection authorities. By measuring the flow rate of molten polymer passing through an orifice under specified conditions, the tester evaluates material viscosity traits and processability, delivering critical reference data for plastic material R&D and quality control procedures.

Measuring Principle: MFR and MVR Determination

Melt mass-flow rate (MFR) and melt volume-flow rate (MVR) are obtained by extruding molten specimens from the plastometer barrel under predefined temperature and loading conditions.

Melt Mass-Flow Rate (MFR)

Extrudate segments collected within set time intervals are weighed, and the extrusion rate is computed and documented in g/10 min.

Melt Volume-Flow Rate (MVR)

The system captures data either by detecting the piston travel distance over a fixed duration or by recording the time consumed for the piston to travel a designated distance, with the final result expressed in cm³/10 min. Mutual conversion between melt volume-flow rate and melt mass-flow rate is feasible when the material density under the given test environment is available.
