The new OCS X-Ray Pellet Scanner XP7 is able to detect metal defects in highly transparent and opaque pellets by having the innovative X-ray technology in the measuring system which analyses images of the pellet stream in real time. Due to the different absorption of the X-rays in the metal and in the polymer, the embedded metal particles can be detected from a size of 50 µm, which improves the quality control of polymer and product. Contaminated pellets detected will be sorted out by a multi-track air nozzle system.

Possible testable raw materials are such as highly transparent pellets and opaque pellets.
