The MI-ROBO from GÖTTFERT offers the possibility to
perform fully automated melt index measurements for
granules and powder materials.
This includes fully automated filling of the test barrel,
automatic execution of the measurement, automatic cleaning
of the test barrel and die, as well as die change. With
automated filling, an unlimited number of consecutive
tests can be carried out without operator intervention.
The MI-ROBO can be individually configured for the
respective polymer through various optional features.
Determination of melt density (Method A)
The MI-ROBO optionally enables the automatic determination
of melt density according to Method A in accordance with
ISO 1133. The melt volume is recorded in relation to the
melt index, and the density of the material is calculated
automatically.
This procedure increases reproducibility and minimizes
operator errors – ideal for precise material analysis and
quality assurance.

More than just MFR and MVR
Add-On
Additional extension of our standardized Melt Flow Indexers
mi2, mi3 and mi40
With our modular Add-Ons, GÖTTFERT Melt Flow Indexers can
be flexibly expanded. This way, a classical plastometer becomes
a versatile system for comprehensive material characterization.
Depending on the application, additional functions can be
integrated. This makes our instruments suitable not only for
standard testing, but also for demanding tasks in quality
assurance, development and process optimization.
MELT DENSITY VISCOSITY
DIE SWELL
MEASUREMENT
ELONGATION
When determining the Melt
Volume Rate (MVR) according
to Method B, the extruded
volume per unit of time is
measured via the piston
speed in cm³/10 min.
The melt density can be
measured directly and used
for converting between MVR
and MFR.
This Add-On requires a
laboratory balance as well as
the optional melt cutting unit.
With the “Viscosity Measu-
rement” Add-On, the mi40
becomes the mi40 visco.
This enables the plastometer
to perform viscosity measu-
rements in accordance with
the Capillary Rheometer
standard ISO 11443.
The intuitive handling of the
plastometer is combined with
the extended material
characterization capabilities
of a Capillary Rheometer. This
option allows viscosity to be
measured quickly and easily,
making it suitable as a QC
criterion, for example in
incoming goods inspection.
The Die Swell Measurement is
an Add-On from the series of
GÖTTFERT Capillary
Rheometers.
With the help of a laser
measuring head, which can
be adjusted in height, it is
possible to measure the
material-dependent swelling
of the extruded polymer
strand.
This Add-On is particularly
important for process optimi-
zation and quality control in
companies processing
elastomers (HDPE, PVC).
The D-MELT consists of a
GÖTTFERT Melt Flow Indexer
(Plastometer) mi40 and an
integrated HAUL-OFF
system.
The specially developed
D-MELT measuring method
makes it possible to
determine both the melt flow
rate (MFR) and the melt elast-
icity (ME) with only one filling
of the test barrel.
The HAUL-OFF system, which
measures the melt elasticity,
is fed directly by the Melt
Flow Indexer, also called
plastometer.
