Peripheral devices such as feeding systems, application-specific screws, mixer rotors or
extruder downstream equipment combine different modules to a complete downsized
production line for the testing or small-scale production of new materials:
RheoMix Mixers
Are used for mixing, kneading, compounding and plasticizing studies. A typical mixer test
is run at a defined speed (shear rate) versus time, and the material's response is
recorded as torque. The mixing chamber is temperature-controlled precisely by
independent heating and cooling zones, but due to the frictional heat in the mixing bowl,
a change in the material's melt temperature is observed and recorded as measuring
signal. This "Rheogram" (torque, melt temperature vs. time at constant speed) is
characteristic for different materials or blends and often used as a "fingerprint" in Quality
Control for incoming or outgoing product inspection. Different additives in type and
concentration can be measured and quantified objectively through the melting behavior,
consumed energy or melt viscosity (recorded torque).
RheoMex Single Screw Extruders
Proven single-screw laboratory extruders deliver reliable data captured during the
extrusion process to verify process parameters (speed, energy, temperature) for
unknown materials or to manufacture smaller quantities of a new polymer (as strands,
sheets, pellets, blown films) during research and development. The extruders are
equipped with measuring ports for melt pressure and melt temperature to study the
process parameters along the extruder barrels. These barrels are available in different
lengths (length/diameter ratio). A die can be connected to the end of the extruder barrel
to form the polymer melt as strand or film. Special rheological dies (slit, rod, x-die) allow
the determination of shear- and elongational viscosity at defined shear rates. A variety of
screw geometries to customize the extrusion process with different compression ratios,
venting and mixing sections is offered. Standard feeders for pellets and special feeding
systems for powders, pastes, liquids or highly viscous rubber complete the set up.
