Plastic Extruders Visit us at NPE10!   Plastic Extrusion Equipment Plastic Extruder Types Single Screw Twin Screw Gear Box Extrusion Lines Plastic extruders take raw plastic material in bead shape through a gravity feed hopper in the barrel. A screw in the barrel rotates and forces the beads through into the heated barrel. In turn, the plastic extruder melts the plastic. Usually the plastic is melted gradually as it goes down the pipe.
