Preform Inspection

We offer several vision inspection systems for the quality assurance of preforms - no matter whether the inspection should take place inline, offline or in a lab.

Quality control of preforms

INTRAVIS offers premium quality control systems for plastic bottle manufacturers, fillers, injection molders and preform producers. A comprehensive inspection of each preform for a huge range of defects takes place. Moreover, measurements are carried out in the areas of the thread, body and gate. Even the cavity number of each preform can be read providing detailed cavity related statistics.

No matter whether you would like prefer a small, budget-friendly monitoring system or a high-precision laboratory assistant: our preform portfolio offers multiple solutions which can be integrated into the production line or used as an offline system.
