Many things can go wrong in your attempts to create a glass container; drag marks are one of them. If you don’t know what these are, they are fine vertical laps that exist close to the neck or shoulder of your product. Chances are that if you have experienced this complication yourself, your machinery is faulty in some way. Do not worry though, as we are here to inform you all about these issues and how to overcome them.

If your gob happens to be too extensive and not large enough in diameter, then you may end up with drag markings. To counter this, lower your gob’s length and expand its diameter until the desired levels are reached. Glass that’s too cold can also result in a few drag marks, so increase your feeder’s temperature in order to avoid any problems.

When there’s an inadequate degree of swabbing being performed, then the chances of you ending up with drag markings heightens. Simply swab properly if you wish to prevent this. Drag marks can also come about as the result of dirty blank moulds, so change your own if they have seen better days.
