INLINE MEASUREMENT | PROCESSING Pellet purity
Inline inspection can not only be applied in the melt. The latest technically demand- ing plastics, such as those used in the medical sector or in the latest generation of high voltage power cables, require the highest levels of product purity. “We see a strong demand for highest material purity among all plastic manufac- turers and processors worldwide, as well as in compounding,” says Ralf Kulenkampff, Head of Sales, Plastics at German inspection technology firm Sikora. “For inline inspection and sorting of plastic
pellets, Sikora offers the Purity Scanner Advanced. Originally aimed at requirements in the cable industry, the system quickly became a standard for quality control of XLPE pellets,” Kulenkampf says. “Today, the Purity Scanner Advanced is also prevalent in raw material manufacturing and processing. Our customers appreciate the highest detection rate, process stability, reliability, and simple handling of our system. This applies for all customers: cable manufacturers, raw material producers, contract sorters and compounders.” Kulenkampff says the use and capabilities of the
Purity Scanner Advanced depends on the applica- tion and what the customer wants to detect, which accounts for its modular design. When inspecting XLPE pellets during high voltage cable production, for example, a two camera system would include optical camera and X-ray technology. In this combination, the X-ray camera ensures the detec- tion of metallic impurities inside the pellet as well as on its surface down to a size of 50 microns. Burns or other contaminants on the pellet surface are
detected by the optical cameras and automatically sorted out. Sikora says the optical
cameras in the Purity Scanner Advanced system allow for discoloration of transparent materials to be reliably detected. The integration of its blue LED technology improves performance by avoiding shadow detection. Sikora supplies complete
systems. “Our portfolio includes the inline Purity Scanner Advanced to inspect plastic pellets of any kind and to sort out impurities. Further-
more, we offer two laboratory systems, the Purity Concept X with an X-ray camera, and the Purity Concept V with an optical camera.” German contract sorting specialist Sortco has been using two Purity Scanner Advanced Systems at its plant at Niederzissen since March of this year, primarily to sort transparent, mostly unreinforced natural and, to a lesser extent, coloured plastic pellets. “Black specks are the focus of our sorting work. In addition, we remove all discolorations that have a different colour than the polymer to be sorted,” says Hilger Groß, Head of Sales & Quality Mangement at Sortco.
