Inline detection of preform and bottle defects

Kirin Techno-System Co.'s (Japan) inline preform inspector can detect cracks, chips, scratches, burnt spots, flashing, bubbles, and other defects at a speed of 330 units per minute. A special image- processing algorithm enables separation by defect type. Images of defective bottles are also stored.

The supplier also offers an empty PET bottle hybrid inspection machine for defects and leakage (0.2-mm diameter pinhole) that can inspect up to 700 round PET bottles or 630 square PET bottles per minute. This unit can also detect off-centered gate marks in addition to a variety of cosmetic defects. —[email protected]
