The next time you are in flight, pay close attention to the polystyrene (PS) cups used by many airlines. It could be there soon will be an in-mold label on the cup. That, anyway, is now a possibility, as proved by a trio of companies at last month's Fakuma exhibition. The three---injection molding machine manufacturer Engel, moldmaker Glaroform and Beck Automation- teamed for a molding cell processing PS cups which were in-mold labeled with PS labels.

The cell included an Engel speed 180/55â¨running Glaroform's 4-cavity mold at 3.3-sec cycles. Shot weight was 41 g, with each cup weighing 10.25 grams and having walls 0.5mm thick. Using a side handling system, Beck Automation (Oberengstringen, Switzerland) placed the labels and simultaneously removed the completed cups.
