Equipment for Compounding, Reactive Extrusion, Devolatilization, Foaming and Direct Extrusion
NPE2024: Leistritz to focus on advances made via twin-screw extrusion.
At NPE2024, the theme of the Leistritz Extrusion exhibit is The Race to Success, which is representative of the continued advancements made possible via twin-screw extrusion to make better products at a lower cost. The following equipment is on display:
ZSE-60 MAXX co-rotating twin-screw extruder: The 60-mm MAXX features a modular design for barrels and screws that are rated for 425°C operation. Auxiliary equipment integrated with the MAXX includes an LSB-side stuffer for downstream introduction of fillers into the process section and an LSA swing gate strand die with provision for filtration.
ZSE-40 MAXX co-rotating twin-screw extruder: Well suited for color concentrates and small lot production, the ZSE-40 MAXX also features a modular design and an LSA swing-gate strand die. An AC water-cooled motor is integrated into the machine design, which operates more quietly than air-cooled motors, and eliminates unwanted air flows in the plant.
ZSE-27 MAXX co-rotating twin-screw extruder: The ZSE-27 MAXX is suited for research and full-scale production and features a quick-change flangeless barrels design for accelerated barrel reconfiguration, as well as a gearbox is attached to a dovetail mounting plate that enables the gearbox to be quickly repositioned to facilitate different L/D ratios testing. All electricals are integrated into a roll-around stainless-steel base, and an Allen-Bradley PLC/HMI controls architecture will be displayed.
ZSE-18 twin-screw extruder: Well suited for R& D, the ZSE-18 offers a fully segmented design and can operate from ½ to 10+ kg/hr. A base-mounted LSB side stuffer enables downstream introduction of fillers, fibers and shear-sensitive materials into a process melt stream. A highly customized front end consisting of a gear pump positive displacement device and candle filtration assembly will be mated to a film die. All electricals are integrated into a roll-around stainless-steel base, and a Siemens PLC/HMI controls architecture is a brand new feature.
ZSE-12 twin-screw extruder: Exhibited for the first time at NPE, this machine is suited for continuous operation and is designed for low rate and small batch processing. Modular stainless-steel barrels and screws are assembled on splined shafts. The process section can be configured for liquid injection and multistage devolatilization. The feed section is equipped with a patented microplunger feeder, which facilitates processing as little as 50-100g batches.
