|ZSE-100 twin screw extrusion pelletizing system|
Leistritz offers wide ranging twin screw extrusion technologies and services
Leistritz manufactures modular, high-speed twin screw extruders primarily for compounding, devolatilization, reactive processing, and direct extrusion for rates from 1 to 10,000 lbs/hr. Systems for pelletizing, film, sheet, fibers and profiles are supplied. Areas of specialization include equipment for heavy-duty compounding of filled engineered materials, as well as medical device and pharmaceutical installations. In addition to extrusion systems, a wide range of technical services are available, including custom engineering, a New Jersey process laboratory, and an ongoing Twin Screw Workshop training series.
Company adopts 'cradle to cradle' approach.
Firm launches 'cradle-to-cradle' operation.
There won't be many blown-film lines running, but there is still much in the way of innovation going on in extrusion and compounding.
The process offers great opportunities to extrude a better product at less cost, but it’s not for everyone. The formulation, product mix, and anticipated volumes must be carefully assessed to determine whether DE is the preferred manufacturing methodology.
New twin from Coperion also pumps up output by 30%
In blown film, equipment and material suppliers have come together to push five-layer technology into non-barrier applications previously held by three-layer films.
There are many techniques known to operators and plant engineers for increasing the performance of a twin-screw compounding extruder.
NPE is typically a competitive display of the biggest, most dramatic equipment machine builders can muster.
Smaller parts, a wider range of resins and reinforcements,and retrofittable molding equipment were among the news indirect-compounded long-fiber thermoplastics presented at a recent Plastics Technology conference. Extrusion and thermoforming are also new extensions of this process.
Leistritz has installed ZSE-27 and ZSE-50 Maxx twin-screw extrusion systems in its Somerville, N.J., process laboratory to demonstrate the energy savings possible by reprocessing undried PET in-line with direct sheet extrusion.
They’re hardly a startup, having opened their doors 27 years ago this month.
Compounding news at the show includes several new ways to feed low-bulk-density materials faster for higher outputs with corotating twin screws.
Two machine builders have developed super-small, high-tech twin-screw extruders with segmented screws that are said to be truly scaleable machines.
Compounding machinery news at the K Show next month focuses on more torque, more output, and sometimes both, for kneaders, mixers, and twin-screw extruders.
Throughput capacities are going up for compounding equipment of all types.
Injection MoldingSimplified Hot Runners Save Time & CostA new lower-cost hot-runner alternative to valve gating is suited to less critical cosmetic applications where users need predictable and reliable gate opening but not sequential gate operation.
Leistritz in Somerville, N.J., believes it is the first OEM to offer an oil-sealed vacuum pump as a standard option for venting a twin-screw extruder.
New compounding technologies displayed at K 2004 included some unusual ways to broaden the range of products a twin-screw compounder can make.
Compounding news at the K Show includes the use of alternative motors to save space and raise output on twin-screw machines.
The latest sign of an upsurge of interest in direct long-fiber compounding by molders of reinforced thermoplastics is a technology that allows molders to produce their own glass-mat thermoplastic (GMT) composite sheet.
