What It Measures
Melt flow rate (MFR / MFI) of PE, PP, PS, PET, PC and other polymers — tracked continuously, so process drift, grade changes and off-spec material are visible the moment they happen, not after the lab reports back.
How It Works
The instrument rapidly melts pellets or powder and holds them at constant test temperature. A gear pump, driven by a servo motor, pushes a defined volume of melt through a die with the same L/D as a laboratory melt-indexer. Melt pressure and flow are measured, and the MFR is calculated directly — cycle after cycle, with minimal material. Automatic validation keeps results equivalent to lab testing.
Highlights
- Inline and offline test modes in one unit
- Multi-point and single-point calibration
- Automatic validation for lab-equivalent results
- Degassing removes residual air from the melt
- Gentle handling: no shear damage, crosslinking or thermal degradation
- 21.5″ touchscreen interface
- Data via Gigabit Ethernet, RS485, analog/digital I/O (Modbus TCP/IP)
