Extrusion International 6-2025 India & Asia

31 Extrusion International 4/2025 A major focus is the production of high-quality recy- clates for applications with high purity requirements, including solutions for food contact applications, based on corresponding regulatory assessments in the United States and Europe. Process stability, reproducible prod- uct quality and low operating costs are key targets, sup- ported in particular by ef cient devolatilization and continuous melt ltration during operation. MRS extrusion – ef cient devolatilization as the key to quality, throughput and energy savings A central element of Gneuss technology is MRS extru- sion. It combines proven single-screw technology with a dedicated multi-screw section that signi cantly in - creases the melt surface area under vacuum. As a result, volatiles, moisture and odor-forming components can be removed very ef ciently. For processors, this means improved and more consis- tent product quality, reduced odor, fewer gels or optical defects, and a more robust process even with dif cult materials. At the same time, energy and equipment requirements can be reduced because in many applica- tions no complex pre-drying is required. This lowers en- ergy costs, simpli es line design and reduces potential sources of operational errors. Rotary ltration systems – continuous ltration for stable processes Stable melt pressure and consistent ltration are es - sential for uniform product quality and economical operation. Gneuss rotary ltration systems enable con - tinuous melt ltration without production interrup - tions – even with strongly varying contamination levels. The RSF genius series in particular combines constant- pressure ltration with ef cient back ushing for auto - matic self-cleaning. This helps minimize downtime, re- duce operator effort and screen change requirements, and limit material losses. Users bene t from a more stable production process, lower scrap rates and higher overall line ef ciency – both in recycling and in demand - ing extrusion applications. Retro t and process optimization – ef ciency improvements without full reinvestment Another focus is on retro t and optimization projects. In many cases, signi cant improvements can already be achieved by upgrading existing lines with modern melt ltration and extrusion technology – for example through increased process stability, reduced downtime, improved output and lower operating costs. This en- ables ef ciency gains without the need for a complete new line investment.
