Tiama’s ‘HOT eye’ sensor is dedicated to defects detection and dimensional measurements at the hot end.

The system is composed of two high-definition cameras and a light source flashing in infrared.

The Tiama HOT eye works with the same principle as the cold end machines by measuring the light transmission.

Synchronised with the IS machine, the sensor records container images and provides statistics, enabling to know on which cavity defects have been produced.

The use of visible cameras instead of infrared cameras allows a complete inspection of the containers, there is no limitation due to the radiation of the articles.

With infrared technology, areas like the bottom and finish may appear very bright or dark (see above), making it difficult to see defects in these critical zones.

Detecting critical defects at the hot end is a first step in the process monitoring approach. The system's high-quality images facilitate quick and accurate analysis by operators.

Real-time defects detection at the hot end allows for immediate adjustments to the process parameters, preventing the creation of faulty containers that might only be identified later at the cold end.

The Tiama HOT eye has proven its effectiveness. Data measured by plants equipped with the Tiama HOT eye has shown that seven times more critical defects have been seen at the hot end since the system was installed.

On average, blocked pallets were reduced by 20%, and customer complaints were halved, leading to considerable cost savings.
