The highest purity of plastic granulate ensured

Material purity for demanding areas, such as medicine, semiconductor manufacture, molding of plastic parts with precision tools, film extrusion, aviation and automotive industry or during the production of medium, high and extra-high voltage cables, is essential to the quality of end products. Therefore, from the production to usage, the purity of plastic granulate for the petrochemical industry, for polymer manufacturers and processors, such as producers of compounds and master batches, has the highest priority.

PURITY SCANNER ADVANCED for optimal purity of plastic granulate

SIKORA sets new standards with its PURITY SCANNER ADVANCED/PURITY SCANNER for the area of online inspection and sorting of plastic granulate. The systems combine an X-ray camera and up to four optical cameras and therefore, ensure a 100 % purity test. The X-ray camera detects, amongst others, metallic impurities within granulate, the optical cameras detect discolorations, scorches as well as “Black Specks” in transparent and on the surface of translucent pellets. Discolorations are detected by color cameras. Contaminated pellets are automatically sorted out. Efficient display systems provide a gapless recording, comprehensive statistics and a clear visualization.

PURITY CONCEPT V and PURITY CONCEPT X for offline inspection, analysis and sorting

SIKORA‘s portfolio also includes the PURITY CONCEPT Systems for automated offline inspection and analysis of plastic granulate, used for sample testing or incoming goods inspection. The material sample is placed on a tray and moved through the inspection area. Within seconds, the sample is automatically inspected and contaminated material is highlighted by the projector directly on the tray. Images of contaminated pellets are shown at a monitor, automatically evaluated and reproducibly cataloged.

The systems are based either on X-ray technology (PURTIY CONCEPT X), detecting contamination inside of colored pellets, or an optical camera (PURITY CONCEPT V), detecting contamination on the surface of transparent, translucent and colored material. Contamination are evaluated regarding their size and clearly allocated so that a follow-up inspection is possible anytime.

Since these systems automatically inspect, detect and analyze, they are more precise, more reproducible and more reliable than human, eye and manual light table. They significantly contribute to an automated quality control and process optimization.
