At Plastimagen in Mexico City, Mexico (November 7-10, 2017), SIKORA will introduce the PURITY SCANNER, a system for online inspection and sorting of plastic pellets. The system combines X-ray technology with an optical measuring system, which is the only technology at present that reliably detects contamination inside of plastic pellets and on its surface. Another member of the PURITY SCANNER family is the ADVANCED system that also combines X-ray and optical technologies. Of particular interest is the flexible adaptive camera concept. Depending on the type of contamination and application, optical high-speed cameras as well as X-ray and color cameras are positioned for optimal contamination detection. Contaminated pellets are automatically sorted out and only pure pellets enter the extrusion process. “In conversations with customers we observe that not only inspection, but also data collecting and recording are becoming increasingly important,” says John Dognazzi, President of SIKORA International. “After all, it is this information that is finally leading to optimized processes and end products of the highest quality,” concludes John Dognazzi.

Visitors will also get to know the SIKORA PURITY CONCEPT Systems that are used for smaller volume throughputs and for applications where sampling analysis or incoming goods inspection are sufficient. Alternatively, these analysis devices can be equipped with X-ray technology and optical cameras and detect contamination in pellets, flakes, films/tapes and crosshead parts. The PURITY CONCEPT Systems can be used for analyzing pellets, which were detected and sorted out by the PURITY SCANNER. “The interaction of online and offline inspection and analysis allows a complete control of the cleanliness of the material and the setup of a database in order to further improve processes and to avoid future contamination”, states John Dognazzi.
