Leistritz Extrusion will be presenting new and wide-ranging twin screw extruder related technologies at the NPE 2018 (booth # W5545).
Somerville/NJ (February 2018) – From May 7 – 11, 2018 the plastics world will meet up at the NPE 2018 at the Orange County Convention Center, Orlando, FL. Leistritz Extrusion will also be a part of it, showing not only the latest equipment novelties, but also introducing complete twin screw extrusion lines.
ZSE 18 3D filament system
The ZSE 18 system will consist of: loss-in-weight feeders, the ZSE 18 co-rotating twin screw extruder, gear pump, die to produce 1 to 5 mm 3D filaments, a custom air-rack for air quench cooling and sizing of the filament, belt puller, laser gauge and winder. The control system will integrate closed-loop pressure control to ensure a tight tolerance product.
The ZSE 18 system is ideal for in-line compounding of polymers with additives and active-fillers to quickly develop new filaments and formulations. Formulations can be modified “on the fly” for rapid sampling of modified filaments with different formulation percentages. A sample can be produced every 10 minutes.
The ZSE 18 system is rated for 425 C° operation, for high-temperature engineering polymers, and designed to process 1 to 20 kgs/hr. Larger production ZSE systems are available for filament, profile and shape extrusion. The system as described will be available for testing in the Leistritz Somerville, NJ process laboratory after NPE 2018.

ZSE 50 MAXX twin screw extruder system
Leistritz will also display a ZSE 50 MAXX that includes a modular design for barrels and screws and an insulated barrels cover. What’s unique about this system is that the extended length facilitates multiple downstream operations including multi-stage venting, liquid injection and up to two LSB 50 XX side stuffers for filler/fiber introduction into the melt stream. The ZSE 50 MAXX is ideal for wide ranging compounding and can be equipped with a 600 HP AC motor and produce 1,000 kgs+/hr at 1,200 screws rpms.

The LSB XX series is supplied with a high OD/ID ratio of the screws (2.0) and can also convey materials with very low bulk densities. The screws can be segmented. This way they can be configured according to the needs of the raw material in use. The LSB XX can be adapted to the processing unit via tie rods. Another advantage of this side stuffer is that barrels can be jacketed for cooling or heating. Internal cooling of the screws is an optional feature.
Other equipment in the booth
- ZSE 27 MAXX co-rotating twin screw extruder with air quench pelletizer attachment
- Comparison of PLC/HMIs: Various control architectures will be displayed, including Allen-Bradley and Siemens model PLCs and HMIs. Both types are equipped with remote VPN accessibility for process analysis and troubleshooting
- Leistritz Elongational Rheometer: This device mates to an extruder and a small amount of the melt flow is diverted, measured and returned to the extruder to facilitate on-line analysis and adjustment of shear and elongational viscosities
