45 Extrusion International 6/2018 sion. These impurities are eliminated by the PURITY SCANNER ADVANCED. The inspection and sorting system combines X-ray and optical technolo- gies and detects contamination inside the granulate as well as on its surface. Thus, transparent, diffuse and colored materials are reliably inspected for pu- rity to100%. Contaminatedgranulates are detected and automatically sorted out. The result of the purity testing is significant because, in the extreme case, unusable material can be made usable again. “The material does not contain foreign particles and the qual- ity is improved up to 100 %”, explains Ofner and adds “the PURITY SCANNER ADVANCED is currently the most ac- curate sorting equipment available on the market. With the optical sort- ing systems used so far, generally only up to 96 % purity can be guaranteed. Then, however, impurities remain un- detected in the pellet. The SIKORA device is combined with an intelligent processor system, which analyzes and visualizes the sorting. For Minger, especially the statistical evaluations of the detected contami- nation sorted by number, size and frequency as well as an image gallery of contaminated granulates, which were detected by the optical cameras and X-ray camera, are of importance. All information is automatically saved and available in Excel format as well as image file. Also recorded is data such as the possible duration of the order, material type, throughput and rejec- tion rate. This way, a full traceability is possible after a project has been com- pleted. “We use the production data as reference for future orders. Fur- thermore, we forward the informa- tion as a final report to our customer, who receives absolute technical trans- parency about his product and the production process”, explains Ofner. Customers appreciate Minger‘s qual- ity standard and know that sorting technology is a core element in the production process in order to ensure premium plastics. This strategy has a positive impactonall stagesof thepro- cess chain. “By supplying clean, evenly reprocessed regranulates, we are sup- porting an automatic and smooth production process of plastic prod- ucts”, explains Ofner. Furthermore, Minger enables a sustainable material cycle by using innovative sorting tech- nology from SIKORA. “Impurities are eliminated, the processed material can be reused and waste reduced”, says Ofner. Hence, regranulates from Minger are nowadays a competitive alternative to newmaterial, providing economic benefits whilst also protect- ing the environment.
