X-Ray Pellet Scanner (XP7)

X-Ray Pellet Scanner (XP7)

The new OCS XP7 X-Ray Pellet Scanner detects metal defects in highly transparent, opaque, and colored pellets, which improves the polymer and product quality. The innovative X-ray technology in the measuring system of the XP7 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. Contaminated pellets are sorted out by a multi-track air nozzle system.

Testable Raw Materials

  • Highly transparent pellets (e.g., PET, PMMA, polycarbonate)
  • Opaque pellets (e.g., polypropylene, polyethylene, ABS)
  • Colored pellets (e.g., dyed or pigmented pellets in various shades)
  • Recycled pellets (e.g., rPET, recycled HDPE, recycled PP)
  • Specialty pellets (e.g., biodegradable or high-performance polymers)
