Advantages of Grooved-feed screw and barrel:

1.The slotted feed section can be used as a forced transport to significantly increase solids transport stability (ie extrusion stability). Even if there is a great change in the back pressure caused by adjusting the gap of the die mouth, the yield fluctuation is very small.

2.In addition to increasing the solids transfer rate, because the polymer axial pressure gradient in the slotted feed extruder is less than zero, the melt pressure flow in the screw channel is in the same direction as the drag flow (non-notched extruder reverse), so Improves melt transfer capacity. Therefore, the output of slotted feed extruders is higher.

3.As the screw speed or back pressure increases, the melt temperature rises only slightly.

4.can be processed non slotted feed extruder difficult to process polymer, such as high molecular weight high Density polyethylene (UHMWHDPE), powder, etc.
