Extruder Vacuum Vent at Shirley Roache blog

Extruder Vacuum Vent. Part of the way along the extrusion barrel, the diameter of screw root is reduced to. Sometimes a vacuum port may be used on the extruder. Using a wood or plastic tool to clear out a vent is highly recommended. Zoning elements isolate two operations within the extruder, such as to facilitate a melt seal prior to a vacuum venting zone. Blockage of the vacuum vent. Understanding when a vent is vulnerable to vent flow and what causes vent flow is key to managing, minimizing or mitigating it. When the material starts blowing up from the direction of the die you are dealing with a blockage in the degassing zone. A clear or better understanding of what causes vent flow and when the extrusion system is vulnerable to vent flow could prevent or provide a rapid response to a vent flow. Vent flow occurs when polymer or compound flows out of a vacuum or atmospheric vent opening, preventing air and gases from escaping the extruder. Not only can vent flow cause product defects, it can create an undesirable mess. The few extruders that turn clockwise.
