Extruder Open Screw Barrel

The extruder open screw barrel is used in the feeding section, the natural
exhausting section and the vacuum exhausting sections. Depending on the
materials produced, the placement of the open barrel is different. The
opening shapes can be square, rectangular, and round above the natural
exhausting port and the vacuum exhausting port, and there must be a suitable
"material stopper" arranged in the opening to reduce the return of material.
