Method A, MFR
The Cflow extrusion plastometer consists of an extrusion barrel which is heated exactly to a preset temperature, a die of standardized diameter, and a piston with a weight applied to its upper end.
- The extrusion barrel is filled with the material to be tested.
- After a defined preheat time, the material is extruded through the die by the force of the applied weight.
- The extrudate is cut off at constant time intervals and weighed. The result is the melt mass flow rate (MFR), which is calculated from the extruded mass per 10 minutes.
- This method is suitable for individual tests with lower specimen quantities.

- The modularly designed Mflow extrusion plastometer for determination of melt mass flow rate (MFR) and melt volume flow rate (MVR) .
- The Mflow can be operated as a stand-alone instrument via a modern touch display, or with ZwickRoell’s testXpert III testing software.
- Tests can be performed to the following standards:
- Methods A and B to ISO 1133
- Methods A, B and C to ASTM D1238
- ASTM D 3364
- JIS K 7210
- Optionally, you can expand the Mflow with, for example, the pneumatic weight lifting unit, with or without cleaning function, or the weight pegging unit.
