Modular and flexible

Expand your extruder

We offer a flexible platform for the characterization of polymers with our extruders. The extruder serves as a base unit to which various additional add-ons can be modularly added.

This allows the extruder to be optimally adapted to the individual requirements of each application. In its full configuration, the processing behavior can be comprehensively characterized.

Success Story: Our testing instruments in use

Roundtable: Know-how directly from our lab

Flat Film Unit

Flat die 70 / 120 / 150 / 220 / 320 / 420 mm
Film width up to 400 mm (greater widths on request)
Take-off speed 0–50 m/min
Take-off roll diameter max. 600 mm
Infinitely adjustable height setting
Controllable shaft for coreless winding

Filter Measuring Head

Reduced downtime through preheating of the subsequent filters
Measurement in accordance with DIN EN 13900-5
Fast filter change without stopping the extruder and melt pump
Analysis of purity and homogeneity
Quantitative determination of the concentration of contaminants and viscosity inhomogeneities affecting quality
Multi-layer, replaceable filter discs
Operation at constant rotational speed (shear rate)
Compact design

Continuous Output Measurement

The melt strand is guided to the outside through a deflection head or an MBR rheometer measuring head
Below the capillary, the strand enters a collecting container positioned on a balance
The balance continuously determines the weight and transmits it at precise time intervals to the evaluation software
Extension of the operating program for connection of a laboratory balance
Supplied with collecting container and connection cable from the balance to the EXTRUSIOMETER

RHEOTENS

Infinitely variable speed
Free selection between linear and exponential acceleration
Setting, steering of measuring process and test analysis with Windows Program RHEOTENS 97
Different pull-off wheels – to be specified depending on usage
Tandem pull-off wheels
Already existing RHEOTENS machines can be upgraded with new electronic box as well as “RHEOTENS 97”
