Extrusion, leak and measurement give the hand in the stand of Gneuss in Equiplast 2011

This extruder, already established in the market, will show the processing of flakes of Bottles of PET to no knitted without presecado.

And is that, from his presentation in the fair K 2007 the system multi rotante of the extruder of Gneuss has established quickly like a technology of avant-garde for the processing of flakes of bottles of PET. More than 15 of these extruders especialesse have sold by all the world for applications of plates, in Germany, Russia, Brazil, Argentina and North America.

The main advantage of this extruder is that it allows the processing of the PET without presecado with a simple system of empty of rings of water to process the PET and obtain products of high quality. This can obtain thanks to the scoop and patented section of processing. Based in a conventional extruder of simple screw, the System of Screw Multi Rotante (MRS) is a drum that contains eight cute screws satelitales comandados by a system of transmission of piñón and gear of rings. The barrels cut in the drum are opened roughly 30% and this provides an optimum exhibition of the mass melted.

Thanks to this design, the desvolatilización is 50 greater times that in a cute conventional screw, and this with an empty of 25 to 40 mbar. Avoiding the need of a system of empty height and of a presecado, the MRS is an extremely economic alternative and efficient in front of the conventional technologies. Other considerations in his favour/favor are the simple and robust design together with an attractive price.

Incidentally, the MRS also offers optimum results of decontamination. Inclusos And can transform scrap of postconsumo highly contaminated obtaining products without residual smell.

The results of the RSFgenius, considering the typical ranks of processings, measure in significant growths of the operation of the lines of production, besides the system of autolimpieza situates it in a position of technological leadership in the market.

The Unit of Products of Technology of Leak of Gneuss will present his rotary systems for mass melted in the fair Equiplast with advanced technology. With the last generation of systems of leak of mass melted, RSFgenius, Gneuss allows important savings regarding the levels of material used for the cleaning of the filter and the consumption of energy fixing new standards no equalised/equalized in the market, as it ensures the signature.

Thanks to the optimisation/optimization of the geometry of the channel of mass melted has been possible to increase the area of active leak between a 30 to 40% in the models RSFgenius 75, 90, 150, 175 and 200. The increase of the area of leak offers an important advantage since for equal levels of production and of leak allows the utilisation/utilization of an immediately inferior model in size.

This has two advantages: by a part, the cost of specific investment for the system of leak can reduce and on the other hand, the necessary space, even in the most compact lines of extrusion, for the installation of the filter can achieve more easily by the size of filter more compact and small. There is not need of resignar the advantages of a high quality of leak by the spaces reduced in the lines of extrusion. Also it will be able to opt the processor for choosing the biggest model and obtain a finer leak or a reduction of the differential pressure.

For this reason the system of cleaning of the last generation of RSFgenius instruments with a totally electronic control. This ensures that it minimises/minimizes to the maximum the loss of material during the cleaning and the elements filtrantes change   only when it is absolutely necessary.

Technology of measurement Gneuss

From the last edition of the fair Equiplast to date, the complete line of the transductores of pressure of mass melted of the area of businesses Measurement Technology of Gneuss has been modified, like standard, to the technology NTXTM-that does not use mercury like half of transmission, and that allows measured still more reliable and exact that with mercury. With this step, Gneuss has fixed new standards regarding confidence and environmental security. The second novelty is the system of surveillance of the pressure of the extruder (EPM). Gneuss Is the first manufacturer of transductores of pressure of mass melted in offering a system that fulfils/fulfills with the increasing European requirements for the salvaguarda of the excessive pressure in the extruders.
