Twin Screw Extruder(STBN)

High Performance & High Torque Gearbox

We use a gearbox supporting high efficiency and high torque for the extruder.

The thrust bearing is multi-stage tandem type and corresponds to high-speed turn.

Besides, an optimized the gear placement results high output, low vibration and low noise.

Segment-type Screw

The screw has many element types, which are respectively, put into a key shaft (normal torque specifications), a corner spline shaft (high torque specifications), or an involution spline shaft (super high torque specifications).

Since we prepare the various specifications of the elements, a various screw design is possible.

Segment-type Barrel

We respond to various needs by putting special barrels, i.e., side feet barrel, a liquid note barrel, a vent barrel, a dehydration barrel, as well as a normal barrel.

In addition, by improving the processing precision, we realize L/D=60 and show high ability in re-active processing particularly.

High Performance

Although the screw turning speed is high (high output), we have made the clearance between the barrel and the screw narrow to the limit, by improving the processing precision.

Consequently, we have developed a high performance extruder for the wiping characteristics (self-cleaning characteristics).
