Screw barrel for extruder machines

The Barrier Screw design is different from the single flighted Conventional or General Purpose Screw design in that it introduces a secondary flight, typically at the beginning of the melting or compression zone. The purpose of this flight is to act as a “barrier” between the melted and unmelted plastic. In a Conventional/General Purpose Screw the melt pool can form an insulating layer around the unmelted plastic, keeping it from melting efficiently. A Barrier Screw doesn’t allow this to happen, because the melt pool and the unmelted pellets are separated into two different channels. Therefore, the melting process is more controlled and efficient.
