Grooved Barrel Extruder Screw

Grooved barrel extruders are popular in the market because of their high output, low temperature extrusion, and low energy consumption. Users in China call it a high efficiency high speed extruder. Grooved barrel extruders have a grooved feeding barrel, which is the most distinctive feature compared to single screw barrels. A grooved feed extruder screw is used in combination with this.

It’s a new barrier screw with a forced feed screw structure. Based on experience, it combines the barrier screw, straight Maddock or spiral Maddock, and Pineapple to meet the high speed requirements of the grooved barrel extruder. This combination of forced feed screw can generate high pressures in the feed section and continue to influence the structure in the following sections. Die pressure does not affect output much anymore. Additionally, the screw’s feed section develops a lot of pressure, which reduces fluctuations during extrusion. The screw increases output linearly with screw speed. The grooved barrel extruder screw is combined with a grooved feeding barrel to get higher output.

Advantages and application of grooved barrel extruder screw

It features a high plasticisation speed, a large feed volume, and a stable current.

We offer our customers a better balanced screw structure. The screw has a reasonable structure, is easy to assemble, has a long service life, is highly productive, and consumes little energy.

In addition to solid wall HDPE pipe extrusion, it can also extrude PPR pipe, MPP pipe, coil pipe, corrugated wall HDPE pipe, and insulation pipe. Furthermore, it is a standard configuration for the production of high-quality plastic blow film extruder and blow moulding machine.
