DSM micro-extruder (DSM Research B.V., The Nederland) has 15ml volume capacity, co-rotating twin screw and the temperatures in the six heating zones range from room temperature to 400oC. The extruder can be fit with fibre and tape dies for the direct extrusion of fibres and tapes. The machine has computer telemetry giving data indicative of the viscosity, speed (rpm) and force (N).
The Extruder E 20 T of the TEACH-LINE® series are particularly aimed at the field of training and education. In combination with a wide range of modular downstream equipment, plastics processing techniques can be studied on a small scale.
Heating is provided by three barrel heating zones, two of which have air cooling and the inlet zone is water cooled. An easily removable hopper simplifies material changeovers and cleaning. Dies are connected using a quick release C-flange which simplifies mounting and de-mounting.
The Collin twin-screw kneader is used in development and production of all types of polymer materials, such as thermoplastics, thermosets, elastomers, paints, foodstuffs, doughs and pastes. The control is arranged ergonomically in an operator panel positioned above the extruder. The controller serves for 15 temperature regulation zones, screw speed control, ampere meter or torque measurement, melt temperature and pressure measurement.
A number of processing tasks can be carried out, such as:
