Air, ceramic, stone or metal inclusions which can occur during the manufacture of glass containers are considered minute foreign objects in the glass.  These inclusions hold potential dangers to product safety – stress, cracks, chipping, and glass breakages.

Glass containers with inclusions are less stable when placed under mechanical or thermal stress throughout the process chain. Furthermore, there are various sources of danger on the line: bumpy transport to the filling line, impact pressure and collisions, high temperatures during hot filling, pasteurisation and sterilisation.

Metal inclusions, which have extremely high expansion coefficients when things get hot, can lead to glass breakage. It not only impairs product safety due to the intrusion of dangerous foreign objects, but also the efficiency and productivity of the complete line.

The line stops each time until fragments and splinters have been removed from the machine and the conveyors, which affects the production times and the output.

Full container inspectors in the HEUFT eXaminer series can reliably detect foreign objects in filled lines using pulsed X-ray technology and accurately reject filled glass containers – even inclusions in the packaging material, the glass wall itself.

However, when inclusions are only first identified during the full container inspection, the finished product ends up in the bin, no matter its final quality. The packaging, to which the closure and labels have already been applied, is wasted as well.

To counteract the above, an empty glass container inspector which detect inclusions before the filling process and removes the containers in question from the production flow is, therefore, a great investment.

The HEUFT InLine II IXS provides more detection accuracy in the Heuft Inline series. The optical examination covers the full volume of each empty container. Foreign objects in the glass and the inner area of the packaging are detected thanks to a new generation of X-ray flashes.

The system can detect minute glass splinters on the base of the container and the finest hairline cracks in the glass before the filling process. It prevents product and material waste, costly product recalls and product liability cases.

The empty glass container inspection results in fewer standstills and product faults, while increasing product output and line efficiency in the filling process for beverages, food and pharmaceuticals.
