Designed as an inline solution with a minimal footprint, the PreWatcher III is the most compact preform inspection system that has ever existed. It also includes the most elaborate cavity number reading. In only 8m², the PreWatcher III aligns the preforms gently by centrifugal force. Eight cameras ensure accurate inspection.

The PreWatcher III inspects preforms for:

  • Geometrical characteristics such as length and shape deviations
  • Material defects
  • Color
  • Notches and holes in the gate
  • Sealing surface
  • Cavity number reading
