Gneuss Kunststofftechnik GmbH celebrated its 25th anniversary on October 29th and 30th with around 150 international guests in the form of an anniversary symposium. The family owned company has plenty of reasons to celebrate. What started in 1983 with the idea of a new type of screen changer has long become established as the Rotary Melt Filtration technology in the industry and has provided the company with continuous growth. Today, the company is run by the company founders, Christel and Detlef Gneuss, together with their sons Daniel and Dr. Stephan Gneuss.

Over the past 25 years, Gneuss has worked constantly on developing and enhancing its range of process and pressure constant Melt Filtration Systems, so that today the perfect solutions are available for the cost effective and efficient filtration of practically every polymer melt. Throughout the world, more than 4.000 Melt Filtration Systems from Bad Oeynhausen are operating in the production of raw materials, film, sheet, in compounding together with other polymer processing applications and in the recycling of contaminated polymers.
In a presentation during the symposium, Daniel and Dr Stephan Gneuss not only discussed the positive development of the company over the last 25 years, they also showed how well equipped the company is positioned for the coming years. Thanks to the latest development from the inventor, Detlef Gneuss (a special multiple screw extruder) complete system solutions with trail blazing technology are available. Especially for the growing area of PET processing Gneuss has in addition to the well established Melt Filtration Systems which were developed specifically for this application, a matching extruder available, which offers gentle processing of this material. The MRS immediately convinced the market: 6 units have already been sold since its introduction at the “K last year.
Top Class Lectures
It was particularly important to Gneuss to use the opportunity of their first quarter of a century not simply to present the company and its products but to create and offer a pleasant and familiar atmosphere for communication and discussion. For this reason, the entire event took place at the Gneuss company premises which were transformed by tents for the occasion. This was where the participants met for a Gala reception on the evening of the 29th and for a convivial get together on the 30th following the lectures and product demonstrations.
Presentation by Prof. Dr. Menges during the anniversary symposiom

Innovation to see and touch
After the presentations, all the guests had the opportunity to see demonstrations of new developments together with enhancements of existing products from the company’s business units Filtration Technology, Processing Technology and Measurement Technology.
Demonstrations in Gneuss‘ technical center
In the Gneuss processing technical centre, the guests had the opportunity to witness the innovative new MRS extrusion technology in operation at first hand, together with the Rotary Melt Filtration System RSFgenius 60 and the Gneuss Online Viscometer, operating at 120 kg/h., processing PET bottle flake to (strand) pellets. The advantages of the MRS are of particular importance when processing PET without pre-drying. Thanks to the large, rotating single screw drum with 8 to 10 integrated satellite screws, the extruder has an enormous devolatilising capacity. Thanks to the large melt surface area in the degassing zone, a vacuum of only 20 mbar – which can be achieved with a conventional water ring pump - is sufficient. Without the cost and time penalty of drying the material, a high quality final product is achieved.
On a second pilot line in the form of an MRS35 extruder, Gneuss showed that this new extruder technology offers new opportunities in the manufacture of chalk filled LDPE micropellets thanks to its extremely good mixing effect.
The guests were of course impressed by the technical advances and were very complimentary with regard to the organisation and atmosphere of this successful event, by and together with the Gneuss family.
