MI-3

The GÖTTFERT MI-3 is a semi-automatic machine with fix installed measuring weights matching the highest standards.

  • ISO 1133
  • ASTM D1238
  • ASTM D3364

The MI-3 melt index tester (plastometer) has an integrated, fully loaded weight magazine with electrical weight lifting and manual weight selection.

Due to the high-precision displacement sensor, even very low or very high MFR/MVR-values can be recorded with high precision. The external piston guidance on the guide rod of the test weight makes it possible to measure even very sticky materials with high repeatability. The test chamber with exchangeable test barrels can be swivelled out for easy filling and cleaning.

The device offers users in quality control and incoming goods inspection the possibility to automatically perform MFR or MVR measurements according to ISO 1133 Procedure B as well as ASTM D1238 Procedure B. With an optional cutting device, the measurements can also be evaluated according to ISO 1133 Procedure A and ASTM D1238 Procedure A. With special capillaries, measurements can also be performed according to ASTM D1238 Procedure C ("half-die") or ASTM D3364.

In addition to the standardized MFR and MVR measurements according to ASTM and ISO, GÖTTFERT Plastometers have various add-ons which offer additional functionality.

Highlights
  • Swing-out test chamber design for convenient filling and cleaning
  • High-resolution displacement measurement (0.006 mm/imp.) with automatic resolution determination
  • Pre-compressing with additional weight
  • External piston guidence 
  • Integrated magazine with up to nine test weights from 0.325 kg to 21.6 kg with manual selection
  • Other test weights available on request
  • Electrical weight lifting
Optional Units
  • Manual capillary plug (special heated version for high temperatures available)
  • Automatic capillary plug
  • Automatic or manual melt-cutting unit (even for very sticky materials)
  • Nitrogen purge for hydroscopic materials
  • Alternative steel grades for barrel and piston with higher corrosion or abrasion resistance
  • Data protection of parameters and results via uninterruptible power supply
  • Pneumatic ejection device for viscous materials with 50 kg or 100 kg force
Add-on

GÖTTFERT melt indexers come with different options. Furthermore, we also provides add-ons, which are extending the functionality of the device. The following add-ons are available:

  • Die Swell measurement 
  • Directly connected laboratory scale for determination of the melt density
