Parallel Counter-Rotating Twin-Screw Extruders
The supplier:
Hapro
The parallel counter-rotating twin-screw extruder is used for more accurate simulation of industrial extrusion under laboratory conditions.
The version is equipped with additional pressure sensors, making it possible to better monitor changes in material pressure along the barrel, adapter and die.
HAPRO Parallel Counter-Rotating Twin-Screw Extruder Video Overview
Main Tasks:
- laboratory simulation of industrial extrusion;
- production of sheet, tube and strand samples;
- evaluation of plastication and pressure stability;
- testing of PVC compounds;
- material preparation for pelletising.
Applications
For PVC processors, this is one of the most useful laboratory extruders. It makes it possible to test a formulation, assess melt quality and identify potential processing issues in advance.
