Reimelt Henschel MischSysteme GmbH has developed its first compounding line specifically to run highly filled wood-plastic composites and sold it to eco-Profil NV.
Eco-Profil is using the compounder to extrude, with in-line compounding, wood-plastic terrace decking at its plant in Upper Franconia, Germany. The production line includes an RHC 95 compounder with co-rotating twin screws and an ESE 180 single-screw melt extruder.
The closely intermeshing screws have a diameter of 95 millimeters, or about 3.8 inches. The outer-to-inner diameter ratio is 1.66, giving the twin-screw extruder a large free volume. That features allows high output even at low screw speeds and an optimum residence time for a gentle compounding of the material.
Pre-dried wood flour is fed into the compounding extruder's melting zone through a twin-screw side feeder.
Reimelt Henschel is based in Kassel, Germany.
