Microcompaunder extruder HAAKE Minilab II complete with molding machines and a set of molds allows to produce composite materials based on polymer matrices and shape of these samples of different shapes (bar, dumbbell, cone) for further tests. Maximum temperature of the extruder to 350oC, working pressure up to 1200 bar injection.
A continuous supply used to force the material into the extruder. The system has a vertically rotating auger, which compresses and conveys the material from the hopper through the feed zone of the extruder to the screw extruder.
Extruder:
HAAKE Minilab is mikrokompaunder extrusion compounding and extrusion for very small samples of materials (about 5 g).
Due to the presence of return channel sample can circulate in the extruder. Return channel is designed as a flat capillary rheology with two pressure sensors. Because of this can be obtained primary rheological data on current properties of the sample.
With the bypass valve with pneumatic sample may be the extruded through a die.
Injection molding machine HAAKE MiniJet II is designed for melting and molding samples for further testing of samples of small volume.
