Gneuss will show solutions for stable recycling and efficient extrusion at CHINAPLAS 2026, which will take place at Shanghai, China on April 21-24.

Gneuss’ booth at CHINAPLAS 2025 in Shenzhen, China.

Key exhibits include OMNI recycling systems, MRS extrusion technology and Gneuss rotary filtration systems, including the RSFgenius series.

These technologies support processors in running stable operations even with challenging material qualities, reducing both energy and material consumption and upgrading existing lines efficiently, in recycling as well as in conventional extrusion and compounding.

OMNI recycling systems

OMNI recycling systems are designed to reliably handle incoming material streams with fluctuate properties and to produce high-quality recyclates in an economical way. Depending on the application, a wide range of polymer streams can be processed, including PET, polyolefins and styrenics.

Featuring efficient devolatilization and continuous melt filtration during operation, the recycling systems enable process stability, reproducible product quality and low operating costs.

A major focus is the production of high-quality recyclates for applications with high purity requirements, including solutions for food contact applications, based on corresponding regulatory assessments in the United States and Europe.

MRS extrusion technology

MRS extrusion technology combines proven single-screw technology with a dedicated multi-screw section that significantly increases the melt surface area under vacuum. As a result, volatiles, moisture and odor-forming components can be removed very efficiently.

Even with difficult materials, the extrusion technology enables improved and more consistent product quality, reduced odor, fewer gels or optical defects, and a more robust process.

At the same time, energy and equipment requirements can be reduced because in many applications no complex pre-drying is required. This lowers energy costs, simplifies line design and reduces potential sources of operational errors.

Rotary filtration systems

Gneuss rotary filtration systems enable continuous melt filtration without production interruptions, even with strongly varying contamination levels.

The RSFgenius series in particular combines constant-pressure filtration with efficient backflushing for automatic self-cleaning. This helps minimize downtime, reduce operator effort and screen change requirements, and limit material losses.

These result in a more stable production process, lower scrap rates and higher overall line efficiency, both in recycling and in demanding extrusion applications.
