IS Machine

At Unipack glass, quality is of paramount importance.

First happens at the IS machine, immediately after the bottle is formed. Here, the line operator, with the quality control checker, does hot end sampling for dimensional checks.

Hot-end ware rejection is an automatic process to ensure quality of the bottles after bottle swabbing. Next, the bottles are put into an annealing chamber, where they are gradually heated and cooled to de-stress.

The bottles then pass through a series of automatic and camera inspection checks by equipment like M, M-Cal, Veritas and VISIGLAS. These machines check for body defects, neck finish, bubbles, foreign matter etc.

The bottles are finally automatically shrink-wrapped, and a sample of the packed bottles is put through a QA process to check for defects.

The container used for transport is fumigated and also checked for cleanliness and hygiene prior to stuffing.
