Vented single screw extruder

SEVENTSTARS MACHINERY single screw extruder is a magic machine that takes the plastic pellets and creates long, skinny shapes known as extrusions. There is a large screw inside the machine that pushes the pellets through a tube. The pellets heat and turn gooey as they pass through the tube, resembling the gooey cheese on a pizza. The plastic is forced out through a small hole at the bottom of the machine, where the extrusions we just spoke of are made


Now that we understand something of how the machine functions, let’s consider the significance of these targets. One big reason is efficiency. We can vent the machine to remove excess air or moisture from the plastic pellets. This lets the machine operate more smoothly and quickly, creating more extrusions more quickly.

Improving efficiency and quality with a vented single screw extruder

Another reason is quality. When we vent, air will escape and the plastic pellets will heat more evenly. This is going to get you consistent sized and shaped extrusions every time and that’s useful for pipes and tubes and things


Having seen how venting operates, we can depend on some advantages. One major advantage is that venting runs something called “flash” off. Flash occurs when additional plastic comes out the sides of the extrusion and appears messy. We can solve that by venting the machine so it won’t happen, and get cleaner, nicer extrusions.
