Co-rotating Twin Screw Extruder
The SAT series is our most popular twin screw extruder. With a powerful gearbox and precise screw elements it has a flexible processing range and a wide operation window, and it is configured with modular screw elements, barrels, melt filtration and pelletizing systems.
- Screw diameter, SAT40 to SAT135
- 41–130mm
- Specific torque
- 9–10.9Nm/cm³
- Maximum screw speed, by size
- 400–800rpm
- Output, by size and material
- 150–3,500kg/h
Where the SAT series sits
A parallel co-rotating twin screw extruder: the two screws are parallel and rotate in the same direction.
- Co-rotating
- Counter-rotating
This series
SAT for most compounding tasks
A multifunctional extruder. We also provide individual solutions according to customized requirements.
More torque
U+ Series
Up to 18 Nm/cm³, for super engineering plastics and high fibre loadings.
U+ SeriesLower investment
EC Series
Standard torque with a permanent magnet motor, up to 800 kg/h.

Drive
High torque gearbox
The split-transmitting principle is applied in the USEON-patented gearbox with a digital online monitoring system. Each gearbox is assembled with precise positioning for torque balance.
Specific torque of the SAT75
Motor 280 kW at 600 rpm
Total torque T = 9550 × 280 / 600 = 4,456 Nm
Centre distance of the two output shafts D = 6 cm
Specific torque = T / (2 × D³) = 4,456 / (2 × 216) = 10.3 Nm/cm³
Heating system
Instead of traditional casting heaters outside the barrel, we use cartridge heaters made in Germany inside the barrel. This saves energy.
Cooling system
Two inputs and outputs on each barrel give faster and more uniform cooling.
Supporting frame
A traditional barrel is supported underneath and expands upward by 0.2–0.5 mm when heated, leaving uneven gaps between screw and barrel. The SAT barrel is supported in the middle and expands up and down uniformly, so the gaps stay even.
Strand die plate
The die plate is matched to the pelletizing system of the line.
