Barrier screws are a way to increase throughput of single-screw extruders and to improve melt quality. They keep unmelted solids in the primary screw channel by increasing the flight clearance on the downstream side, while letting the fluid melt escape over the barrier flight into the secondary channel. That way, the solids do not randomly disperse into the metering section. This allows for extrusion at higher pressures and higher rates without sacrificing melt quality.
