Multifaceted expertise

Gneuss offers a wide range of services to ensure permanent production consistency and product quality in the manufacture and processing of plastics.

Recycling Technology

OMNI Recycling Systems
The plastic recycling systems are suitable for a wide range of different polymers in various forms, including bottles, trays, injection molded products, blow molded parts, films and fibers. The OMNI, OMNImax and OMNIboost systems can process materials such as PET, PA, PP, PS, LDPE, HDPE, LLDPE and many more.

Filtration Technology

Rotary Filtration Systems
The patented Gneuss Rotary Filtration Systems enable fully automatic, process and pressure constant filtration. The main characteristic of these filtration systems is the rotary disk with its ring of screen cavities, located between two solid steel blocks.

Extrusion Technology

Extrusion Technology
A key aspect of Gneuss extrusion systems is the proven MRS (Multi Rotation System) technology, which opens up new possibilities in degassing. Later, the MRSpure technology was introduced for individually optimized melting and decontamination, as well as the MDS extruder (Multi Dimension System) for single screw degassing.

Process and Control Technology
The use of patented measurement and control technology allows Gneuss to simplify extrusion processes while at the same time increasing their reliability.

Viscosity Measurement
Gneuss’ Online Viscometer VIS allows the permanent proven real time monitoring of polymer viscosity. Its rugged design and measurement accuracy are well proven. The viscosity measurement takes place without material losses. The design permits easy cleaning, without influencing the process.

Vacuum Technology
The standard vacuum systems operate with a simple and robust water ring pump with a standard vacuum level of down to 25 mbar. Systems for vacuum levels down to 1 mbar can be supplied. The gas and particle separation is simple and environmentally friendly.

Measurement Technology

Sensors and Accessories
Gneuss Melt Pressure and Temperature Sensors are characterized by their extremely high precision, combined with a high degree of robustness. Consistent application of latest technology ensures permanent quality control during the production process.
