Extrusion technology

Gneuss – hall A6 booth 6501

Innovative MRSjump extruder with high decontamination performance and a viscosity boost in one single extrusion step. Gneuss is presenting its new MRSjump extruder. As with the proven MRS extruder, the extrusion process does not require any pre-treatment of the input material, such as crystallisation or pre-drying of the material. Short residence times, low thermal and mechanical stress on the melt and efficient degassing have characterised MRS technology, says Gneuss. With the new MRSjump extruder, the MRS screw section has been modified and extended so that, in combination with a 1 mbar vacuum unit developed for this purpose, the viscosity of the polyester can be raised or stabilised to the desired level directly in the extrusion step. A downstream IV build-up in a solid state polycondensation (SSP) is not necessary. For the first time, the processing of materials with low or highly fluctuating input viscosities is possible in a single extrusion step. The compact design of the MRSjump extrusion line requires little space, energy and maintenance compared to other solutions on the market.

Filtration technology

Gneuss filtration technology is introducing an additional size across its line of rotary filtration systems. The models RSFgenius, SFXmagnus, SFneos and CSFprimus are now available in a size 110, which offers almost 20% more active screen area than the size 90 for each model, depending on the specific model. In the past the next size up was the size 150, with a jump of more than 50% in active filtration aera. The new intermediate size will ensure an optimised and cost-efficient filtration solution for every application. Rotary filtration systems operate continuous, automatic, process and pressure constant. They are characterised by a filter disk on which the screen cavities are located in a ring pattern. Screens can be changed on the part of the filter disk that is not active in the melt channel, while the production process continues to run without any interruptions or disturbances. Gneuss melt filtration systems can be integrated into an existing process and are perfectly suited as a retrofit solution e.g. for demanding recycling applications. The various models differ for example in terms of drive design, encapsulation and whether they offer integrated back-flushing.

Measurement technology

As a machinery manufacturer, Gneuss has the manufacturing capabilities to manufacture even unusual sensor requirements. The lean manufacturing structure at Gneuss allows the company to offer very short  delivery times. Gneuss sensors are available to match regional or application-specific requirements such as Atex, Hart Communication or EAC and are also available with digital IO-Link communication. For special process conditions or difficult places of installation, Gneuss offers individual sensor solutions; new are the rotatable sensor shaft and a flange mounting solution.
